Okay so Angel's seahorses have been relocated to the new 44g pentagon tank... they love their new home... alas it's in our bedroom, guess it makes the room off balance or something so we bought another to match it to put in the opposite corner, this one to replace my 10g nano which primarily houses my stoney corals. Since the stands have a small footprint (20"x20" with a corner chopped off) anything larger than a 10g sump/refuge is impossible. No problem, drill through the floor into the basement for a great big macro fuge and sump looking at somewhere around an extra 100g to the total water volume, providing a place to house a very agressive skimmer without the fear of dumping microbubbles or creating very high flow areas from the skimmer to the pony tank, and many other benefits from a maintenance standpoint.
What about tying both the pony coral and the stoney tank together on the same sump and refugium? Other than the need for a big honkin' pump to beat the 12'+ head pressure to get back up to the tanks and possibly raising the nutrient levels in the stoney tank a bit, think this would cause any issues with either tank?
I'm more concerned for the seahorses point of view than the coral's.
