Yes, I have a cheapo ProClear or something or other I found on Craigslist that came with a CPR90 overflow box. I like a lot of things about running a sump, but not how much CO2 I go through. The overflow box also makes me nervous, but then again so does the thought of drilling my ADA tank.That was my plan until I got a few quotes back. The prices after shipping were just too much to justify. If I can find a pre-built one that satisfies my needs then that will be great I just haven't decided on what brand or model yet and was hoping to hear from some others that have pre-built ones. I was almost shocked when I got the quotes back. I knew that shipping would probably be the deal breaker but for $600 I would just go with the one I linked that has a built in ATO chamber. I don't need anything that fancy but I do like the dimensions of that one. I have plenty of time to figure it out but thought I would hear what others opinions were before I went forward.
Aaron, do you use a sump on any of your tanks?
