FreshaTank Microbial Disc for Water Butts & Tanks

FreshaTank Microbial Disc keeps water fresh and safe by eliminating fungal, viral, and bacterial microorganisms in water butts and fish tanks. Made from natural materials, this long-lasting tablet provides reliable purification without replacement and reduces reliance on harmful chemicals. Simply place the disc in your water butt or tank. Within four weeks, single-cell organisms that contact the disc's surface are eliminated, leaving you with cleaner, safer water. Packaged sustainably to minimise environmental impact. Please note: the disc treats water only, not tank sides or bottoms. Full treatment typically takes up to four weeks depending on tank size.
