My gha was 80% gone after first treatment but came back fast in a week so started a second dose. Not sure how to get all those nutrient out fast enough to prevent outbreak. I did a 30% WC but not enough apparently. Wondering if WC during treatment would be better. A few reefers were doing a water change with fluc in replacement water
I forgot to mention in my update that I did a 10 gallon WC on my 54 gallon tank at Day 7 and Day 14 since I have a canister filter and I wanted to clean out all the dead GHA and keep my nutrients down. I treated my WC water with the 20mg per gallon mix on each WC. I'm doing a 50% WC tomorrow (Day 21), letting my tank settle for a week, then re-dosing for a second treatment. I say I have 85-90% GHA die-off.
