I bought a bottle of Seachem Flourish EXCEL recently to try to eliminate (or at least control) some black beard algae. I used dosing recomendations from threads here on TPTank forum.
As a test, I took 2 buce plants that were covered in bba and submerged them in a bucket with 1 gal. of water. I then dosed at the 5ml per 10 gal ratio (.5ml/gal) on the first day and then reduced to double the recommended dose on subsequent days (5ml/25 gal). After a week of this there was no change in the bba.
I then increased the dose by more than 2x daily for a week and still no change.
DAY 1: .5ml/gal (as per bottle directions)
DAY 2-7: .2ml/gal (equal to 2x daily does from bottle)
Day 8-14: .5mml/gal (equal to 5x daily dose from bottle)
I don't mind increasing the dosage until it works in this bucket test, but there's no way I'd do that in my tank.
I've read several accounts here of people having success with Flourish EXCEL to treat bba, so my first guess is that I'm doing something wrong.
I have not read accounts of people saying it did absolutely nothing, so I'm hopeful it still may work.
Thanks for any comments.
