Today I went out and bought an Aqueon Submersible Heater for my 5 gallon tank. I bought it so I would have the ability to adjust the temp. Well, I set it all up and I noticed that the thermometer wasn't rising even though, according to the heater it was the right temp. Then it hit me. I don't have a filter so the heat wasn't spreading evenly through the tank. The heater has an automatic shut-off so once the water around the heater was the right temp. it would turn off. Leaving the rest of the tank about 4 degrees cooler then I want. I know that I should just get a filter and that it would solve the problem. But, I do not want a cycled tank under any circumstances. Please don't ask why. I just don't.
So, I was thinking that if I got a filter but still treated the tank as if it was
un-cycled. I would have a Filtered Un-Cycled tank.
My questions are... Is this even possible? If so, how many water changes would i have to do to ensure the tank remained Un-cycled? What filter do you recommend?
Thank you for your help!
