Blue Crystal is an advanced method of biocidal control made up of two parts; Alpha & Omega. Together they provide protection against both algae and bacteria all year round. This unique method requires minimum maintenance, offering greater flexibility than other systems. Pool water treated with Blue Crystal is hygienic, clear, odourless and tasteless. Used with a 'shock dose' treatment of your choice, Blue Crystal provides an excellent alternative to chlorine.
Test Tablet Kit contains - 20 Alpha, 20 Dechlor, 50 Phenol Red and 20 Omega Test Tablets.
