When I first got my GBTA I feed often 2 or 3 times a week because I was worried about it loosing its bacteria and bleaching out. Now I only spot feed my nem once a week or so. I have rics and candycane corals that I spot feed with mysis and brine and it is really cool watching them eat. I also feed DT's Phytoplankton every other day or every 2 days. Just started with the DT's about 2 weeks ago but everything looks good. Just watch out I was over feeding and my water quality went down hill very quickly. Oh yeah I feed mysis and brine every other day and NLS pellets daily for the fish.
