APT FIX or APT FIXLITE?Updated a month ago
We recommend APT FIXLITE if you have algae on Mosses, Liverworts (Riccardia, Riccia etc.) Vallisneria (Tape Grass) and more delicate plants (usually hybrids or rare species).
It is normal for algae to develop resistance over time. Nature is amazingly resilient, and algae adapts. If APT FIXLITE does not work, try APT FIX. And vice versa.
