Yea I plan on getting a 100+ gallon sometime soon. And down south here seems like my lil 8 gal biocube is always around 79-82 and sometimes 84. I wonder if the larger a tank is will it be cooler since there is more water? House is pretty cool normally 76-77 but I have the setup near the kitchen in living room so of course its bit warmer there. Just pondering and picking brains here from the more experienced folks. As always thanks for the help to all.Are you planning on getting a bigger tank and planning ahead or is this for your small tank?
