Hy-Clor Liquid Pool Blanket

Bought at Bunnings for $40 Used this chemical as per instruction . The first thing I noticed was the oil slick on the surface of the pool . After a couple days there was a greasy scum line around my pool the pool toys were covered in greasy scum .My pool pump seals started leaking My cartridge filter pressure went up at least 25% and as I could not remove the product i have to clean my filter every day soaking it in detergent . My pool level has gone down approx. 100mm. Hopefully the product will eventually disappear from my pool I returned the product to Bunnings and got a refund. I informed Hy Chlor and they said to return it.
