Sorry for the resurrection, but I have read all I can find on the specific use of Algaefix to treat spriogyra on this an every other forum that comes up on Google. However I have read conflicting info a couple of times. Everyone clearly states to follow the recommended dose and directions of 1ml per 10 gallons, but I have read that people are using it for 3 days... Although the bottle says to use every 3 days... Is it "use for 3 days consecutively" or "every 3days for three treatments"? With the suggested 50% WC before and after treatment, it would seem that what is being suggested is the 3 consecutive days and not the every 3 days per the label.
So if a participating member of this thread could confirm, I would be very appreciative.
And yes I know my cause, its fixed, never had spiro before and hope to never again.
