this is my first time setting up a saltwater tank. its been up and running for about 4 weeks now. i started because while on vacation we were given a wild marine hermit crab so i thought i would give a try. so right now i'm dealing brown diatoms in the tank so it doesn't look the greatest. i have a the hermit, a peppermint shrimp, yellow tail damsle, and i just got a sea hare last night to help with the diatoms. i have built a sump with a refug and a protein skimmer witch is not running right now cuz my pump died. i also built the cabinet below just need to get the drawers built for it.
