    Filter Flush - Contains Sodium Bisulfate

    Bought a product to clean my DE Filter Fingers, it's sold at the pool store as Filter Flush. It has "unique tracer dye", "simplifies use". I suppose this helps when you rinse it to ensure you've rinsed thoroughly. Instructions are to mix 2.5 lbs with 5 gal of water and soak for 12-24 hours. Anyone have experience using this this? The caution label says that it contains Sodium Bisulfate, but that's really the only indicator as to whats in it. Thanks!

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.

    Could be, the physical description in the MSDS you posted says red to purple granular. This is red granular. Other than that the bottle doesn't give me any other hints.

    It's just acids. You can do the same with a clean plastic trash can and some diluted Muriatic Acid.

    I've never done anything to my DE grids but hose 'em off, so I'm no help here.
