Review: Good - Better water quality, fast result. Cheap price good size for one fish tank. Helps water clarity.safe on fish and plants.
Review: Good to have on hand! - I needed to use this since my tank hadn't fully cycled yet, but I do have plants so I wasn't relying on this entirely. It seems to help perk up the system and assist the tail end of the cycle so you don't have to wait for ammonia to build up before you start getting the beneficial bacteria. I'd buy again!
