Tide pools are ok, I've seen them in action. But if it was up to me(MHO) I'd use a Aquafuge. Either be a hang on or a under tank. Better filtration, and smoother operation. I've got a CPR under tank Aquafuge pro. Its a great set up with the skimmer already in the fuge, No more skimmer on the main tank. others will have there opinions.
