I may switch to a tub. I dont think my ambients are high enough Im also having trouble with humidity. Would I be better of switching to a sterilite. Also I like the height on my 20g, it allow for my girl to climb on her wood. Is there any steriltes that have close to the dimensions of a 20g long. Also Im using a dimmer to control my cool side. I usually have to fiddle with it a couple times a day to keep the temp in the good zone. Would another thermastat be worth it.
