I have a red sea and have run Triton for about a year and a half
I use the standard sump that came with my tank , I just added a sump divider to separate my skimmer from my algae
Tank runs great
I got my sump divider from reef dreams which is a European company ( I'm UK ) but a member from the us order from them aswell and had no problems
I have a sump coming from Crystal Reef Aquatics. They are a great company to work with. Very responsive and beautiful/functional sumps. Check them out.
I have a Eshopps r-300 sump and was having trouble getting the fuge size need for Triton. So I bought a 24x24 cure that was on sale for $75 and cut 2 holes in it and put in 2 bulk heads that would dump right into my Eshopps sump. It works perfectly and I have ran my system and his way for over a year and love it!
