I have my 10 gallon tank outside and every day it looses about 1-2" of water due to its so hot in florida... and i just add water normmaly... so my question is, i'm getting a bigger tank out there around 55 gallons do i still have to do water changes with all the evaporation? I could just fill it then 1 week later it will have liek 7" of water gone then fill it again?
