Vibrant works despite the mislabeling of it. But it appears you could probably use algaefix for cheaper since it may be the same thing.
That said, do you have a plan for the nutrients that are going to build up without the algae growing? I personally embrace the algae a good bit. It's actually a filter for your aquarium, it's just ugly. But you need to have something in place to take care of those nutrients if you are going to kill it, and if you had those things in place to start with, then you likely wouldn't have algae issues.
When I use chemicals to deal with algae it's because I want to accomplish 1 or 2 goals.
1. It's an algae I do not want to have, like bryopsis, bubble algae or what not. In those cases I'm just wanting a better algae, aka GHA.
2. It's growing in a place I don't want and/or is messing up coral and getting out of control. So I have a refugium on my 180g, but I'm getting lots of algae in my DT. So I might remove the macro algae in my fuge, kill the algae, and then put the macro back in to use up the nutrients and hopefully only algae will grow there in the future(working so far for the past 9 months).
On the other hand, I have no filters on my 29g anemone tank outside a HOB skimmer. GHA grows all over the tank and I would never kill it. It is my filter, and the algae doesn't bother my anemone or my xenias. Once every month or so, I'll do a clean up and remove a good bit of that algae by hand. That is my nutrient export method of that tank.
2 tanks, 2 different means of nutrient export.
So are you killing the algae as part of a plan, or just killing it because you want it gone?
