Ok so on labor day I dosed my system with reef flux rx to try and kill off my gha. So far it was worked extremely well. Buy, it’s not 100% gone yet. I removed my chaeto and restarted my skimmer after 3 days. The package said do a water change after 14 days, but on line research has said sometimes gha takes 3-4 weeks to die off completely. Should I wait another 2 weeks, or do I need to redose the tank? Also when is it safe to put the chaeto back in?
