For some odd reason I felt I should put an undergravel filter in my tank before I started it up for a fresh cycle and batch of fish. It's a 10 gallon tank and I already have a decent filter setup for it but I thought I could use some cleaner water. Well after doing some more reading and talking to people about UG filters I have concluded that it wasn't the best idea. I've only been cycling for about 3 days and haven't been able to measure any nitrite or nitrate buildup yet. Can I just yank the towers out of the filter and smooth the gravel over it? Would the void under the gravel cause any problems? Or should I just remove some water from the tank and try to pull the UG filter out without making too much of a mess?
