    Great stuff, helps keep my tank parameters balanced. Normally buy it in the pack with calcium, however due to different amounts needed the alkalinity gets used much faster than the calcium. With all the fluval additives being used I have happy health fish, and vibrant, colourful and fast growing corals.
