So I have a 90 gallon tank & I’m going to be adding bio spira bacteria to it to get it cycled & then I’ll be adding two clownfish. I will have this relatively low bio load for a while. Might add a few corals but not too many as of now especially cause I’m just starting out. I bought the autoaqua auto water change + top off & I was wondering how many gallons I should setup for daily water changes? In regards to my filtration I have a 20gal sump with chaeto & a skimmer, 80lbs of dry rock that will eventually turn to live rock & 60lbs of sand (40lbs dry & 20lbs live). I read online a good recommendation would be 5% daily water change which would be 35% per week (31.5 gallons). Is that a good recommendation for me or would I be fine doing less & if so how much?
