I actually had a few of my plants pearl after adding Glute. I did a huge water change, added Glute, and Peroxide(fighting Staghorn algae) and a few of the plants started pearling. This is the first time I have ever seen it in my tank, as I don't use CO2. If anyone knows how to get rid(or at least control) Staghorn algae, I am VERY open to suggestions. What I have tried so far is not working. Water changes every other day, triple dosing Glute, double dosing Hydrogen Peroxide, Spot treating with peroxide, cutting out all ferts, reducing photoperiod to 5 hrs per day. No change. The little bit of BBA in the tank is long gone, but the staghorn hangs on
