Seachem Reef Calcium Liquid Organic Source, 250 Ml

I use it in my snail tank to keep their shells thick

Great product. I use for my mystery snails

I bought this for my aquarium snails shells and this works pretty good. Doesn't make the water cloudy and the smell isn't too strong. Very happy

Because of how concentrated this is (which is typically a great thing, especially for bigger reefs) it’s harder to dose for smaller tanks.Other than that, the calcium seems to have trouble sticking around in the water column. Will do more adjustments and come back to amend my review if the (very mild) issue is on my end

I knew this product would cloud my water, and it did for a couple days. It wasn't too bad though. Based on the directions, which said to continue weekly and increase dosage etc., I thought it would take some time before I'd see results. The shells on my mystery snails improved after the first dosage.
