Great for purifying water for house plants.
"Sheffield Made Plants" on Youtube demonstrated how it works on house plants that suffer from the chemicals in tap water , (lack of vigour and brown edges on leaves). The results were astonishing.

Tip-top conditioner
A must if you want to keep your tropical fish in tip-top condition. Use every water change as per instructions and your fish will love you for it.

Cheaper on eBay
Have been using it for years. Can’t seem to find it in local fish stores, also cheaper to shop on eBay.
