Coroline

[Paulie 069]

Not this one Paulie, this is just ground up coroline in solution and is proven to work as long as you alk and calcium is good it will get coroline to populate faster.

I’d be impressed if it worked

I 've used helix before and works absolutely well. again requires a tank that can grow the coralline algae but will seed it enough that you'll see growth within the first week or 2. much more noticeable when you start with bone white dry rock
