Ok. I have a another Tetra HOB rated for 75+, Ill use that instead. Aragonite was my first choice, but I had read another guys posts swearing by crushed coral. Does it make that much of a difference? And this skimmer I was talkin about was a Rio nano-skimmer. What do ya think? (http://www.bigalsonline.com/Fish_Pr...mmers_Nano-Skimmer_9474817_82.html?tc=default)
