How do you Clean cartrige pool filters with hydrochloric acid?

Answer 1

Cartridge filters can over time become les effective because the material they are made of becomes clogged with calcium. A method that worked well for me in the past before I changed to a sand filter was to soak the whole cartridge in a fairly strong solution of acid. This eats out the calcium and gets the cartridge working properly again. I may be wise however to check that the material of the filter can withstand the corrosive effect of the acid. Cleaners that do this are also available ready made at pool shops.

Answer 2

It is not recommended to clean cartridge pool filters with hydrochloric acid as it can damage the filter material and compromise its effectiveness. It is safer and more effective to clean cartridge pool filters with a filter cleaning solution specifically designed for that purpose. Follow the manufacturer's instructions for the best results.
