What nutrients are in the average basic set up for these shrimps, both shrimp and MTS would have very small bio loads . no real plants in there. Just microbe lift nite out starter bacteria. RO water mixed with microbe lift premium reef salt. Lava rocks, fine black substrate. And about 50 or so MTS. No shrimps yet as its cycling. I thought the moss might have helped with cycle but it went white which I've read means its dying.
