I had a major battle with cyano. But with all ur guys help I'm beating it faster than I ever thought. My tank looks great and it's almost all gone. Thank you all for taking the time to help. Soooo now that my tank looks great. I bought a couple beginner corals ie Xenia and star polyps. I also made an impulse buy 4 days ago an orange frogspawn. I loved it soo much and I wanna do everything I can to keep it alive. I positioned it in medium flow and about 2/3 from the top of tank. I have a 90gal with 4 t5s. I have a 10gal refugium with chaeto a etss protein skimmer I run carbon in a filter sock and a phosban reactor running nitric oxide. I also have a mag with a detritus remover running 24/7. I do weekly water changes 15 gal ro/di water only and use the turkey Baster method to blow off live rock during the water changes. I'm still new to the reef keeping and was wondering if anybody has any tips or suggestions that might make my tank happier? Oh yeah I also dose b-ionic every day.
