Can someone help me I don't know why my RBTAs are looking bad but my sunburst nem is looking normal. I do have some bristle worms like majority of reefers on here parameters are good to go. I also feed them once a week some brine shrimp marinated with phyto but still they dont puff up and its been a while since. My tank is almost 1 year old and all my corals are growing (Acros, Acans, Leathers, GSP, Zoas, Goni, Monti and torches) Still they look rough. I aso do 10 -20% water changes every week just so the parameters stay consistent with nutrients. I also have 3 AI Primes running with whites and blues.
