I just do massive water changes every other day. I have no problems keeping them warm,I use a space heater. I live in Texas so I have a bigger problem with keeping them cool for the most part of the yearmrplaty said:Do you have filters in all them tanks or do you just spend alot of time doing water changes??
Also how do you kepp all of them tanks warm???
Winter is like a vacation from the extreme heat.

I know, I think it's too many changes!
