c'mon man! You were on Al B. FAQt. Just add it to the res every 4-5 days at 1/4 cup for 12 gallons (just did my calcs today)

Seems a bit much. I'm gonna start at about 1/2 that (I'm cheap)

Instead of h2o2, you can use something like this:

You could even make something like them yourself. The idea is that if you cover the algae, it can't get any light and will therefore die.

buy some cheap styrofoam plates and cut them to size to cover each piece of rockwool
