Water Changes
Water Changes
I just received my 300 and am wanting to do a automatic water changer also. I was thinking of drilling a hole in the back of the tank about 9 inches down and having a valve to be able to empty 20% of the tank. I don't see how you are removing water as it looks like you are just pumping water out from your sump, which wont be anywhere near 10%. Can you tell me how you are doing your water changes? Also, do you know what kind of glass the back is?
