Review: Great Product at a Great Price - Great product at a great price will be back for more when run out as long as price hasn’t tripled. Always use after cleaning fish tanks and water change and never had a problem, straight forward easy follow instructions, I prefer to get the larger bottles so happy with size. Fish must be happy and content as always breeding 😂. No spikes in levels so very effective.
Review: 5 stars - I had an issue where unfortunately one of my fish had sadly managed to work its way into the filter. When i awoke the next morning the water needed a quick fix. This i now use often to keep the water at balance. The water comes out crystal clear with just a small amount of the fluid. 5 star product.

### ⭐⭐⭐⭐⭐ Amazing water additive for fussy houseplants.
*by M***N on 25 August 2025*

We don't own fish, however this was recommended for our praýer plant that detests chlorine and all the other detritus put in our water. It has recovered and is thriving on a few drops diluted in a watering can. In fact all of our houseplants seem very grateful! Who knew!!!
