Just set up a free 100 gallon tank that came with a tidepool 2 sump system. I have never used one before, and set it up how I think it should go. It has been running now for 24 hrs without any problems, but I did have to adjust the discharge and intake rates to keep the tank from overflowing or the sump from overflowing. Any suggestions? I this a good system? What do I place in the 3 trays? I currently placed some extra filters from a "behind the tank " in 2 of the drawers. Where can I order the proper items? Thanks!
