Hello, just wanted to run this idea by everyone! During my research I have read to top the aquarium off with fresh water once a week to compensate for evaporation, with a PWC of 15 - 20% every month or so. I was wondering if a 5G change every week would be ok and eliminate the need for the 20% change every month. 5G change a week for a total of 20G a month would be about 20% for me. Any input is appreciated! Thanks!
