Welcome to our forum.
I was looking up the muriatic acid and TSP solution for quantities and came across another method: dishwasher detergent, such as Cascade. Use 1 cup to 5 gallons and soak overnight like the acid bath.Anyone try that?I also read that weekly spraying off of the filter before a thorough cleaning helps prolong the period before the acid bath is required, which makes sense.
Acid washing is only needed if there's mineral deposits on the cartridge. If there's no mineral deposits, all the acid washing will do is shorten the life of the filter.Cascade works, or at least use to, due to the phosphates in it (which have mostly been removed)....same reason TSP works, but cheaper, purer and less "soapy".
