I am wondering how much and how often are your water changes and on what size of tank? 10% weekly, 20%, 5% or monthly, bi monthly
Are you saltwater or fresh?drgnfrc13;3814843; said:I do about 30% bi-weekly and siphon the gravel in my 220g. I would do more, but the most I can change at once during the winter is a little over 60 gallons, because the way I refill the tank is by filling two 34g trash cans w/ water, then using a pump to get the water into the tank. During the summer, I can just use the water hose and change as much as I want to (usually about 40-50%).
