Review on Seachem 116014304 Clarity 500Ml by Amber Robinson

I am changing the tanks from 20 gallons to 37 gallons. I used up all 20 gallons of water but also added new water and new gravel. The filters were from an old aquarium, so I thought the biosystem was already installed. Spring. I added a few small fish and within a week I had organic blooms. I read a lot and they said it would eventually go away on its own because it's not that bad. but for me it was bad enough. I decided to try this product and it worked like magic. Great. Like everyone is talking about him. Highly recommend, also I've added some other Seachum products.
