I have a roughly 35G tank that is cycled with a couple fish in it, I fit a 10G tank in the stand (it was so close, but I had to take off the cheap plastic trim to make my clearance.) I know 10G isn't a lot, but I figure it is better than not having one? I've never done a sump before, and I tried to use the search to find some good links on how-to best set it up, and to make sure I don't drain the tank during a power outage, that sort of thing. Any tips would be great, and advise it its even worth doing a 10G sump. Let me know, thanks!
