heaters

Question
Hi Lynda,
Can you tell me which brand and wattage heaters you use for your unfiltered 5 gallon tanks?  I keep buying the wrong ones.  First I bought a hydor mini, which uses no settings, just heats it up to 4 degrees above the ambient temp!  That one was a mistake...Then, I JUST bought a Hydor Theo, which is supposed to keep it at the exact setting you set it to...well, my temp dropped 2 degrees in 2 days!  So, the directions say to put it in a well circulated area, so it can heat evenly, but since I am unfiltered...it sucks.  I need one that will work in my circumstance.  Thanks!  And then hopefully I can find it at the pet store, I only have a Petco or a Petsmart or walmart to go buy them at around here.  Thanks!

Answer
Hi Liane,
I use Aqua Clear submersible heaters in all my tanks, and have had no problem with them.  You can set them which I like very much.  They may be a little more expensive, but they are worth it.  I'm not sure if they have 25 watts, but they do have 50 watts which is good for 5-10 gallon tanks.  If your pet store does not have them, they might be able to order one for you.
I hope this will help.
