Trough rocks are pure Australian paramagnetic rocks. When placed into the water trough the rocks inhibit the growth of bacteria and algae - which keeps your animals trough clean and fresh for longer!
- Animals urine will no longer burn the grass and it will keep their water clean!
- Trough rocks are straight from the earth - completely safe, natural minerals and no chemicals
- Trough rocks keep water clean - they do not clean dirty water
- Need to be replaced every 4 months for the best results
