I have a fully planted freshwater tank with about a dozen different plant varieties. I have absolutely no fertilizer and this is the only thing I add to feed the plants. My plants are thriving tremendously and rarely ever do I have a yellowing leaf. This stuff is amazing and I have been using it daily for years!!!

Using to control bluegreen algae


I've used this stuff, not only for co2 but it helps to kill cyano bacteria in my 10 that got contaminated from new fish. It helped stop the growth so that I could remove it completely.
