pH levels

[level]

Hey Ron. Can one use an algae destroyer, like the kind you use in a fishtank? It seems to be nontoxic to fish & marine plants. Also I've never noticed an increase in PH levels. Do you know if this would effect veggie/herbal type plants in your system? Active ingredients SIMAZINE 2-chloro-4, 6-bis-(ethylamino)-s-triazine 0.60% inert ingredients 99.40% . Calls for 1 teaspoon per 10 gal. of h2o.KEEP UP THE EXCELLENT WORK....
