POOL BLOCKS All Seasons Algicide are a unique highly effective long term treatment of five 300g slow-release tablets per 1.5 Kg container. In an average 50,000 litre pool, add two (2) blocks to the skimmer basket followed by just one (1) per calendar month to provide long term protection against all forms of algae.
This unique 'once a month' application provides a constant low level of protection and is an excellent 'first step' in your pool care with substantial savings on your chemical costs and minimal pump and filter running times. In larger pools of 75,000 litres, simply add three (3) blocks initially followed by one (1) block every three weeks thereafter, or in smaller pools the individual tablets may be halved.

Pool BlocksBy: John on 16 April 2022I have used this product some years ago. It was very effective in eliminating black algae. I stop using it because it become too costly. Recently I found your prices to be very competitive and hence I purchased from you. Delivery was very quick and it only took a few days to get rid of most of the black algae and all of the green algae. I am confident that with continuous use , all the black algae will be eliminated.
