Hello AA...
Wanted to toss out a "what if" experiment I have going. I have a 55 gallon tank with 12 small Common Goldfish in it and have been removing and replacing roughly half the tank water in it weekly. I have one dual sponge filter in the tank and some basic aquatic plants. I plan to remove a little more water every week until I reach 75 percent. At this point, I'll remove the sponge, replace that with a large air stone and see how the fish do. I'm pretty sure there won't be any difference in the water chemistry, because I'll be removing the water before there's a build up of nitrogen in the water from the dissolving fish waste. With the added aeration from the air stone, the water should be well oxygenated. My thought is, if I remove and replace 75 percent of the water weekly and feed a little every couple of days, there won't be a need for filtration.
Any thoughts good or bad?
