    this tank heater works. it Keeps the temperature in my tank between 76 and 78 when I have no heating lamps on and the tank isn’t under an open window… my little snappers like to get up on it and crawl on top when its time for me to feed them and take them out of the tank they sit there and wait for me to pick them up .. they can’t eat if they are too cold .. if the feeding water tank is too cold or hot or the inside tank is too cold or hot they wont feed properly . so temperature is very important .. this is an excellent product for your turtles.

    Se lo compré a mi tortuga ya que hace no mucho le había pedido un calentador convencional de pecera pero lo rompió, no sé si porque el cristal era frágil y ella se subió encima de él pero esta es una excelente opción porque a las tortugas les encanta subirse en todo, así que no creo que lo rompa. Lo único es que siento que no calienta tanto como los calentadores para peces pero aún así he notado que mi tortuga está cómoda con la temperatura.

    Great little heater, I should of gotten a smaller one due to the size of the tank. But baby 🐢 loves it! Update: just stopped working for no reason, at least I got a couple months out of it

    I’ve had it in my 65 gallon for a while now and have had no issues! Kind of annoying to clean because you have to take it apart but if you don’t have a messy turtle it shouldn’t be that big of a deal for you

    My turtle likes to sleep beside this heater. I’ve had it for a few months now since I bought it and it has been working well, keeps water temperature warm. Easy to clean if there’s debris sticking to it.

    This product does not work. I installed it according to instructions and waited the correct amount of time before turning it on and it just doesn’t work at all. I have this for a hatchling YBS 10 gallon tank. Cannot figure out how to contact the seller either.

    UPDATE: Turns out I was looking for a contact for Tetra when Amazon was the seller. My bad! Any way I initiated a return and they sent me a replacement that works perfectly. It arrived in 2 days and I can drop off the defective one within about 3 weeks at a UPS without even printing a label so I don’t even have to deal with refunds for postage or anything. It took about 5 seconds to handle once I realized I was being an idiot.

    Works great, automatically set to 78 F which is perfect for my baby slider and I have a temp gun to check. So far as soon as the red indicator light comes on I check it and it is right on 77F, and then the indicator light turns off when the temp hits 79 so that is a nice tight little range. I love it. So does my baby. He’s so small that he wedges himself between the cord and the side of the tank and passes out like a toddler.
    In case anyone was concerned, the red indicator light can be easily seen in daytime light but is not a nuisance in the dark. The cord is a nice length and very sturdy and the suction cups are large and powerful. The nice plastic casing around the heater will keep my hatchling from chomping on it when he gets bigger. You literally just tick it in the tank, fill her up, wait 15 min, plug in and you are done. 10/10 recommend, I just happened to get a lemon the first time.

    I had to order this item twice when our turtle got sick. When the first one arrived, there was broken glass and sand/carbon all over the inside of the simple bag (no cushion packing) it arrived in and the box was smashed up. The heater was broken inside and was unusable.

    I contacted Amazon support and they were very nice and agreed to ship out another one without cost or return. The second one arrived in one piece and was put into the aquarium immediately.

    It did do what it was supposed to do which is keep the water at 78 degrees, but I did not realize when I bought it that the temperature was preset and was not adjustable. There is a tiny red light inside that you can barely see that tells you when the heater is on, and it goes off as soon as the water is at 78 degrees. The suction cups did not work well. I found one was okay and the other one had to be pressed down constantly but would still pop up. If you buy this item, just be sure you have enough water to fully cover the heating portion.

    Way cheaper than PetSmart or other places. It works and it lasts. I use it in my turtle tank. Doesn’t take up much space, it puts of no noise at all it comes apart for cleaning and it is easy to use and install. There is nothing adjustable or speeds it has its own temp and will got off and on when the temperature gets below what it is set to be. Always go buy Watts when buying also depends on the size of your tank but well worth it for the money

    El cordón llegó algo lastimado por el amarre pero sin daño al aislamiento del cable, el calentador lleva encendido unas 3 horas no calienta mucho pero se siente que el agua no está tan fría sino más bien fresca. Otro comentario es que la cubierta se abre fácilmente aunque tenga clips.

    I learned this the hard way. My 54 year old slider became ill and all the vet websites said how crucial it is to maintain a steady warm water temp while trying to help him recover. Naturally, my latest glass heater had recently broken, and since I’d gone through more glass tube heaters than I could count throughout the years, I thought I’d go a different route this time and ordered this encased type. I was also tempted to buy this one because after all, it had the Tetra Repto name, a company division supposedly geared to the reptile world. I did not realize it was preset to a certain temp and could not be adjusted by any means. What a mistake! Its only pros are that its suction cups tended to stay in place better than many of its predecessors, and its case is easy to remove to clean. Now, if only it would have actually heated the water! No matter where I placed it within the tank, I could not get it to go above 76 degrees, a temp which is too low as a good maintenance temp that vets recommend for turtles even when they are in good health. For heaven’s sake, it only had to heat 4 gallons of water and it couldn’t do it!! This is particularly confusing to me, since the target demographic for this product is aquatic turtles. So there I was, with a sick turtle and no way to get the water temp up high enough to help him. I had to dry dock him under towels for three days till a new, adjustable heater arrived. I’m so grateful he was able to hold on. He looked so bad, reddish mucus everywhere and he really seemed to be failing. I was bracing myself, almost positive I would lose him. Thankfully, the new adjustable heater came, I got the water up to the recommended therapeutic temperature and he eventually pulled through. I was REALLY lucky. I’m very bummed, though, because I had much going on around here and managed to miss the return deadline, so I’m stuck with this thing. Another point to keep in mind if you are considering this type of heater: A turtle’s health can change on a dime, as I learned late on that Saturday night. What will you do if your little guy takes sick and you can’t immediately provide him with the extra bump in temp you need to give him the warmth his body needs to at least try to help him recover? Those first hours can be critical. All I can say is, keep looking. Preset types in general are just a bad idea. Decent adjustable ones ARE out there and I did find a really good yet affordable one, in the same price range as this Repto model. I’m grateful that I now have a fully submersible, accurate, easily adjustable heater, without glass tubes and encased in plastic that cleans easily. It’s just a shame that my turtle almost lost his life in the process. I’d love to tell you the name of this better heater, but don’t think Amazon’s review rules would allow it. Bottom line:. As I said, If you care about your turtle, KEEP LOOKING! This is NOT the product to buy!
