Ok sorry about the delayed response work beckoned.. So tank specs, 125 Gallon Reef build, about 120 Lbs live rock, 4 fingers deep of sand. Clean up crew is 6 shrimp, about 15 - 20 Snails, 20 - 30 Hermit crabs red and blue legged, two Horse Shoes, a sand sifter star and two brittle stars. For Fish I have two Cardinals, two clowns and I HAD 5 fire gobys, however one decided to jump the tank a few days ago apparently so now I have 4 lol. I have dual powerheads on a wave maker, skimmer and bioball sump but im removing the bioballs this weekend due to the nitrate issues I had and it seems that's the best solution for a reef tank, long term.
