Yes, pond fish can survive freezing, but they must be properly acclimated to the cold temperatures. The process of acclimation can take several weeks and the fish must be slowly introduced to the colder water. If the fish are not properly acclimated, they can suffer from cold shock, which can be fatal.
Yes, pond fish can survive under ice, but they may not be as active as they are during the warmer months. The ice provides a layer of insulation for the pond, keeping the water at a relatively constant temperature. The fish may huddle together near the bottom of the pond to stay warm.
If you live in a climate where temperatures regularly drop below freezing, then a pond deicer is a must-have item. Not only will it keep your fish safe and healthy, but it will also help to prevent your pond from freezing over and becoming inaccessible.
If you have a pond that is less than 50 gallons, you will need a pond heater that is at least 3 watts. If your pond is between 50 and 200 gallons, you will need a pond heater that is at least 7.5 watts. If your pond is larger than 200 gallons, you will need a pond heater that is at least 10 watts.

This was purchased for my little koi pond. Unfortunately, I didn't know that you have to stop the pond from entirely ice over because this is my first year using a fish pond (it came with the house). I wasn't sure that this deicer would be sufficient because the pond was entirely frozen over and we experienced approximately two weeks of single digit temperatures in New York. In addition, the instructions advised using an ice auger if the ice was thicker than two inches. I connected it, then I put it on top of the ice. The deicer did need some assistance from me. The water would collect after melting a lot of ice, making the deicer float (its supposed to float). In order to keep the deicer in contact with the ice, I would try to remove the water as much as I could. It continued doing this for almost 2.5 days before melting through the ice and getting to the pond water. I was shocked to see that my pond had 8–10 inches of ice on it. I was astounded by how much the pond froze as well as how this deicer managed to cut through more than 10 inches of ice. I'm impressed thus far, but I'll wait to see how it holds up over time after reading several reviews that questioned the product's durability.

I used to get so annoyed with our Christmas lights in previous years. I would venture outside in the cold to place lights over the lawn, web lights over the shrubs, etc. It would all look beautiful if I connected them to a timer. When it started to rain hard, the GFI would trip and the lights would go out. I found myself outside in the cold after it rained attempting to determine which cord connection had gotten too wet and tripped the GFI.Then I started covering every junction where two plugs met with regular plastic wrap. Though not perfectly, that functioned well. We would invariably get quite soaked, and I would be skulking around in the cold and rain trying to figure out what the heck went wrong THIS time. This would invariably occur the night we had family over, making us appear like Scrooges who were either too frugal to turn on the lights or too bah-humbug to have turned them off. Really irritated me.We changed anything that was older than a season because we suspected some of the outdated light sets would be the cause of the issue. Nope, rain still caused problems. Given all the moaning and groaning that came out of me every time the damn lights went out, I think my wife was quite sure I was turning into the father from A Christmas Story. I was about to give up on the holiday lights.We have minimized this year. We have two lit trees on the front porch, a wreath with lights on it, and a spotlight shining on the front door. The one exposed connection between the timer and the spotlight is concealed by this tiny device. So far, despite some heavy rain, the combo has worked every night.These tiny devils aren't cheap, but they appear to work. Consider purchasing a few Christmas displays if you're tired of having them up all the time.

Works perfectly, but if you're lucky, prepare to wait 2-3 years.Except perhaps for the 1100 watt ones, I haven't yet discovered one that lasts longer.I often use them for two years. I keep at least 1 in reserve so I can replace it if it fails.I operate two deicers in my larger pond and one in my smaller pond.Aerators are also continuously running in both ponds. Additionally, I have the bigger pond deicers on two different GFIs. Therefore, if one blows the GFI, the other will continue to run.I've tried the more expensive deicers, and if I'm lucky, they do last a year.If I shop, I can virtually get two or more Tetras for the price of the more expensive ones.The bottom heater component must be as thoroughly cleaned up at the end of the year if you want them to last. It would also be beneficial if you could wipe it off in the winter. The heater will malfunction due to buildup.For me, it's a fact of life that deicers only last two years. That is a portion of what ponding costs.If someone has used a different product and experienced more reliable results, please let me know.The Tetra is currently the only option that I have discovered to be worthwhile. I'm done experimenting with those $100 deicers.Give me a deicer that consistently lasts more than three years, and I'll give it five stars.

I've purchased two of these devices totaling this one. The first one continued for a while before eventually tripping my GFI.I purchased the second one since I liked the first one and was pleased with its performance. Where the cable enters the device looks to be the issue (through the brass plate shown in the photo). I had totally submerged the unit in my initial arrangement. In order to prevent the brass plate from being submerged, I positioned the device vertically in this second arrangement and secured it with a fairly wide hose clamp. This arrangement appears to function properly so far.This appliance appears to be made entirely of aluminum, features a thermostatic switch, and uses 120VAC. Since the power cord is only around 6 or 8 feet long, I have it connected to an extension cord. Throughout the freezing season, I have the device keeping my stainless steel, fence-mounted, automatic dog watering dish (Nelson # 1200B) warm (about 2 months here in northern California). This deicer unit is overkill as there is only approximately a gallon of water in it, but I wanted something that truly works.I was worried since I don't know where the thermostat is in the deicer; if it's in the black handle, as in the picture, then putting it out in the open would be a problem. However, I had no problems holding the brass plate and the black handle in the air. The handle wasn't overly hot when I examined it a few times during the first couple of days, so I figured the thermostat was cycling as it should.I have a well as well (i.e. no municipal water source). In order to prevent the valve on the automatic dog watering dish from freezing up from calcium deposits, I feed my dog's water dish with softened water. The outcome is that the aluminum body of this deicer unit has nodules on it after two months (which I assume are some derivative of potassium chloride since that is what I use in my water softener, and the aluminum body of the deicer). I simply wire-brush the nodules off at the end of the freeze season once this deicer has dried. Since the nodules in my stainless steel water dish are absent, the deicer's aluminum must be reacting in some way. I wish this deicer was available in stainless steel.With the condition that they not bury the power line entry point under water, I would suggest this device to others. Likewise, if you have a water softener and feed it potassium salt, the aluminum body will begin to accumulate (something). Since I tried other units and they horribly failed, I rated it four stars.

About two months ago, we bought this de-icer for our koi pond. It hasn't had any issues with the cold, but there was a moment when wet snow did gather on the body (which the manufacture addresses in the instructions). It's nothing to worry about; simply brush it off. My only criticism, other from that, is that the unit's all-black body can sometimes make it difficult to tell it apart from the water around it; I wish there was an indication light I could see from a distance to let me know it is operating.

I've had three of them over the course of the past three plus years, and that's approximately how long they last before they start tripping the GFI sockets—just a little bit past the guarantee term before ultimate breakdown. bought in November 2012, November 2013, and January 2014, and that one just collapsed (about a week past warranty). I kept replacing it since I liked that it was produced in America, but I believe this is the last one. I have a number of heated bird baths that have held up better than when I first started purchasing this item. I would anticipate a basic heater to last more than one season for the price. I apologize, but these could not possibly be any worse.UPDATE: If I had read the instructions, I would have known that these have a three-year warranty, and a new distributor/manufacturer is reportedly in charge of the business at the moment. After making a call to the customer service line, the representative was quite friendly and asked for a fax of the Amazon invoice so they could replace the item. did not need to mail the old unit, and a new unit arrived three weeks later (or possibly a little sooner). I'm unable to comment on how nicely this was handled. Website of the business: www.miller-mfg.com/product/BDT250.html. The new company's customer service, in my opinion, cannot be equaled, but I am still concerned about the lifespan of the device and will monitor how it performs.

Winters may get quite cold where I reside in South Dakota. I chose to try one of these in an effort to use less electricity after using 1500 watt stock tank heaters for a number of years. One is in a 100-gallon stock tank that I have. It prevents the top from becoming covered with ice below 10 degrees. I put one that is floating in the tank when it starts to get cold. After I got it, I was able to save $200 on my first month's electric bill. We have four stock tanks, and I apologize for not discovering them earlier. My power bill was over $500 the previous winter; thus far this winter, the biggest amount has been just around $300.I bought two of these because I liked them so much to use as chicken nipple waterers in my five gallon buckets. One went into each bucket, and they each did a fantastic job. Fresh water is always available to the chickens throughout the winter. The main benefit of them is that, unlike the traditional stock tank warmers, they don't require an additional cage to protect them. Giving my horses and hens water through the coldest winter days is safe and effective.

My 55-gallon stock tank was prevented from freezing by this product. Last night, it was 20 degrees outside, yet thanks to my owlfeed slotted nipple, neither my tank nor the nipple had frozen or developed any ice. I took off the floatation ring and let the heater rest at the nipple's location at the bottom of the tank. Unless you want to deal with watering your animals twice a day in subfreezing temperatures, it is strongly advised. I do use this in conjunction with a 100' extension cord and a GFI receptacle. The vendor's instructions state that using an extension cord is not advised, yet who has a nearby outlet for their animal pens?UPDATE: I bought a second one of these for a different stock tank. The heating element's tang had "304W" stamped on it, which caught my attention. Because several posters had mentioned that in the USA, the huge "W" stands for watts, I got in touch with the business. The "304W" stands for "304 stainless steel," and it refers to the strip of metal that connects the heating element to the plastic body. The "W" is only the manufacturer's ID stamping, not watts, which is a simple error to make. Overall, I'm satisfied with these little things because they work well for the price. I did purchase a "thermocube" to ensure that they are truly running between 35 and 45 degrees Fahrenheit.UPDATE #2: They are still working as of 3/18. I now have three, and they are all still useful. I even had one within the tank that was on for days above the water line (the tank was low and there wasn't enough cord to reach the bottom). It continued to function after being unplugged, cooling off for 20 minutes, and being placed back in the water.
There are a few ways to heat your pond without a heater. One way is to use a pond de-icer. This will keep a hole open in the ice so that oxygen can get to the fish and so that gases can escape. Another way is to use a floating solar pond heater. This will use the sun's energy to heat the water.
If you have a small pond that has frozen over, you can use a few different methods to safely defrost it. One way is to use a garden hose to slowly and evenly thaw the pond. You can also use buckets of hot water, placed around the edge of the pond. Another method is to use a heat lamp, placed a few feet above the pond. Whichever method you choose, be sure to monitor the pond closely to avoid over-thawing and damaging the pond liner.
If you have a pond on your property, you may need to deice it in the winter to prevent the water from freezing over. Deicing a pond is similar to deicing a pool. You will need to remove the ice and then add a deicer to the water. To remove the ice, you can use a shovel or an ice pick. Be careful not to damage the liner of the pond. Once the ice is removed, you can add a deicer to the water. You can purchase a pond deicer at a local hardware store. Pond de
Pond de-icers are devices that are placed in the pond to help keep the water from freezing during the winter months. They work by circulating the water and by producing heat. Some pond de-icers are solar powered, while others use electricity.
A stock tank heater typically has a wattage of between 250 and 300 watts.
A pond deicer is a great way to keep your pond from freezing over in the winter. But how much does it cost to run one? The cost of running a pond deicer will vary depending on the size of your pond and the climate you live in. In general, you can expect to spend about $100 per month to keep your pond deiced. If you live in a climate with very cold winters, you may need to purchase a larger pond deicer or run it for longer periods of time. This will increase your monthly costs, but it will still
