Ionic UV Balance 1 Litre Growth Technology
Ultra Violet (UV) sterilisation is one of the most successful means to control root diseases, such as Pythium in hydroponic systems. However the continuous use of UV will cause certain mineral elements to drop out of the solution very quickly. For the hobby grower with a small tank, this can cause major problems within days. IONIC UV Balance is formulated to make-up the missing elements in the same ratio as is removed by UV. Just add UV Balance to the tank twice a week and a full mineral profile will be maintained.
