How to stop algae on my rockwool and whatever else is growing on it??

Anyone got any tips on stopping the junk ontop of my rockwool

(1) use some hydrogen peroxide to kill it and (2) buy some panda film covers for your RW; that will keep it from coming back. Algae is not a pathogen to MJ; it just competes for the nutrients and O2, making them grow slower and yield less.

Well, you could grow in an OmegaGarden!

How many times are you gonna do this, Bigcool? This is your 3rd new handle this week.

I bought some "Algaefix" at the pet store.
I haven't used it yet. will it be safe for my plants?

Lol, I'm gonna sound like a pimp now cos I used a similar answer in another thread.

Peroxide them then use Hygrozyme in the water, it turns decaying and dead plant matter into food for the plant which prevents root rot, algae and other moulds and stuff and stops its grow back by taking the food source away.

im curious about the algaefix as well.. anyone have any luck?

make sure ur rez temp is below 70 . Stopped the problem for me.
