I personally recommend doing a water change of around 25% weekly. The more you change, the more traces you are replenishing. IMO, 10% just isnt enough. I personally change 50% of my total volume when I do water changes... usually 15 gallons of my total 30 gallons or so.rescuediver19 said:Much appreciated, I am doing weekly 10% changes.
