Ok, so I just found a wonderful 90 gallon tank for a ridiculously cheap price and I'm going to buy it this weekend and get it set up. This is a big jump from my 25-gallon! But I figure that my little guys will be comfortable in one this big for a long time.
My question: How do you all (who have really big tanks) manage to keep it clean? It was really easy with a 25 gallon to empty it out and everything now and then. But with something so much bigger, I don't know how to handle it! Any tips? How often do you change the water? Is there a specific filter that will really do the trick? Any suggestions would be great!
