They seem to work but they did cause an algae bl
They seem to be working my plants look a lot better definitely use them very sparingly because I used as directed and I had the worst black algae bloom and yeah it was kind of reacting the same way it would if you used regular plant fertilizer for your potted plants instead of aquatic. Next time I'm going to buy aquatic specific fertilizer but it definitely is working I'm going to put the rest of them into my dirt regular potted plants I think they'll really enjoy it. But no more in my aquarium.
