55semireef- id say i have a medium bio load, mainly SPS/LPS with some zoas and softies. my cleanup crew is about 35 nassarius obsoleta snails, 2 cleaner shrimp, mixture between astrea (about 8), nerite (about 6), and cerith snails that reproduce non-stop so i dont know how many. i also have a conch that is always sifting in the sand. i feed the tank a mixture of foods about every day or every other day.
