Ok, then...so how do you use API Algaefix?
The reason I ask is this: About 8 months ago I had a turf algae problem that I was dealing with. I chose to try vibrant at the time, and it seemed to be working rather well for me. I decided to buy a second bottle having almost finished the first. Right around that time, I saw the thread on here about Vibrant. I'm not even sure why, but I don't think I would have tried the product if I had thought it was an algaecide.
So now, 8 months later, I'm developing an algae problem again. And I've got a full bottle of Vibrant just sitting there. To dose or not to dose? That is what I am wondering.
Long term I think I can adjust my feeding regimen a bit to reduce algae (I actually like a little of it, and my cleanup crew does as well), but I'm getting tempted to pull out the Vibrant I purchased.
