Baq-to-Bleach conversion w/cart filter

[waterbear]

Your cart will need to be replaced once the conversion is finished. The cellulose fiber could possibly make the cleaning easier until you destroy all the biguinide since it will coat the cart and catch teh baquagoo on it and it might hose off easier. If the cart is too gunked up you will need to soak it in a cartridge cleaner designed for biguinide to get the baquagoo off of it. Once your conversion is complete put in a new cart and you will probably only have to hose it off monthly and soak it yearly (the best soak for a cart in a chlorine pool is one cup of electric dishwasher detergent powder such as Cascade or Electrosol to each 5 gallons of water. Soak 24 hours and hose off. Don't use this until the conversion is complete and you have installed a new cart.)

The cartridge that I am using is a heavy plastic mesh type that I just purchased last year (cost $140). Since they are not that cheap and, since my conversion is almost complete, I was hoping to give it a thorough cleaning (maybe even an acid bath) and continue to use it. Has the media been damaged somehow? The filter is running fine.

Thanks again.

Checking online the cartridge is a Sta-rite PLM 100 modular cartidge.

It will probably be impossible to clean all the baquagoo out of the filter and I would really recommend replacing it. Acid washing will make it worse. You might be able to use an enzyme based cleaner on it but standard filter cleaners and acid are NOT compatible with biguinide.
Good news is the cartridge will last MUCH longer once you are using chlorine. With biguinide they really need to be replaced yearly. With chlorine, they can last up to 5 years with proper care.
