I am just looking for everybodys opinoin of how much and how often you do water a change.

I do 15g weekly on a 90g plus sump so I would guess about I have about 80-85g of total water volume.

I do 20-25 gallon per week on my 180 gallon. Total volume probably around 200 gallons. 55 gallon qt tank I do 15 gallon per week, only because I run no filtration besides a sponge filter.

I try for five gallons a week on my 75 gallon (plus sump).

But things come up...
