I have a biocube 29 with 30 punds live rock, 20 pounds live sand. I have 8 snails, 5 hermits and 2 clowns. Last time I got my water tested everything was 0 except nitrates were around 40. Ph was 8.2 and salinity was 1.026. My temp stays right around 80. This was before fish were added. They were added 4 days ago and I haven't had the water tested since. This is my first reef tank. I was thinking about maybe an xenia, frogspawn, or what looked like a brain. Thanks.
