Hi everyone. So I'm new to the hobby of saltwater but have kept freshwater for years. I have a 30gal saltwater tank that has been up and running for about 5mos. Live rock, sand, a few fish, cleaning crew, no coral yet (too soon but someday). Here are my problems: 1. I have a calcium precip and have done a couple water changes in the last couple weeks but every morning I wake to those darn white dots all over my rock and glass. So I scrap them off and it happens all over again. How do I get rid of this stuff?
2. Even with the precip which has been going on for a few weeks my levels are good and all inhabitants are fine but I recently bought an emerald crab...I swear the thing has killed and eaten two of my turbo snails and just tonight I caught him EATING MY BLENNY! I loved that little guy/girl! Do these crabs really eat this stuff? is he not getting enough food? Any help on either problem would be appreciated.
