Review on Optimal Pond Water Conditioner - Seachem Pond Prime by Jessica Hill

God I'm glad I found this. I love my small ornamental pond and waterfall, but between evaporation, splashes from the waterfall, and possibly (probably) a leak somewhere behind the waterfall, I filled the pond with a large amount of water twice a day. That meant using a lot of dechlorinator and the first one I bought was really expensive. It's a lot cheaper and does a great job. It also purifies the water!
