    High Quality

    Posted by Robert Davies on 23rd Jan 2020

    I purchased this along side with some Phosphates from GLA for my reef tank. The reef community is loving the results using GLA fertilizer. Increasing the nitrate in my tank has never been easier. I struggled to keep my nitrate existing not to mention my phosphates. Thanks GLA for providing us reef folks with a great set of products at a fantastic bargain.
