I could use your advice on another dose.It is coming up on 2 weeks on Monday that i dosed Reef HD Algae buster using their dosage on the bottle of 1 capsule for every 20 gallons,which you thought was only a half dose.I still have some hair algae and bryopis left in the tank it is better the last couple of days i have been using a toothbrush on the rocks and letting the filter sock get the loose pieces floating around.My question to you is should i wait to dose again and also the dosage i would need for around 170 gallons.I think i would need 20 capsules from pay=less.Someone said their capsules were 200mg caps so at that rate it would be half of the dosage that we've used. I'm not sure why they chose that dosage. I was under the impression that it was pure Fluconazole and nothing else added so again I question why they chose to go with half. Maybe @ReefHD can chime in and answer that one.
