@Carlos Danger As I'm on day 12 as of an hour ago, I'll see if I can go the 14. Have a bit of cyano also on a coral. Was going to do a wc, dose for cyano, wc, then retreat if not all gone. Skimmer back on line, very dry skimming with cup in place. Phos bottomed out so been dosing. Sheesh, ya need it down and it comes down and then you gotta add... No3 ranging from 5-20. It's come down so tank going through some changes as the bryopsis goes bye-bye. I sure don't want to trade one bad case for another! I'm also stopping weaning off dosing of vibrant and nopox
