I change my water out every 2 weeks and i change 5 gallons out of my 40 gallons.(20%) i think thats 20%)
I am not sure what that equates to over a month. It is 12.5% every two weeks but since the water is mixed with the existing water before the next 12.5% change I would not know how to guestimate the actual monthly percentage. It would be less than the sum of 25% but how you would go about determining a fudge factor I am not sure. Using the 20% rule for heavy bio loads and 10% for a reef without fish is just a rule of thumb. Testing your water and adjusting over time is a better long term maintenance consideration.I change my water out every 2 weeks and i change 5 gallons out of my 40 gallons
