## Questions & Answers

**Q: With a cartridge/de hybrid filter, do i have to backwash or clean the filter 48 hours after application of product? thank you.**
A: 1-Clean or backwash filter.Make sure DE filters are properly cleaned and charged with DE before adding product.2-For phosphate levels over 1000ppb, add 32oz (1L) per 10,000 gallons. DO NOT add more than 48oz. (1.5L) at a time.3-Shake bottle well prior to application. With circulation pump running, add the recommended dose to skimmer.4-Some clouding may occur. Run the pump and filter for 48 hours continuously without backwashing or cleaning the filter.5-After 48 hours, vacuum to filter.6-Backwash or clean filter.7-Retest the phosphate level. Repeat steps 1-6 if necessary.For DE & Cartridge Filters: Do not add more than 48oz (1.5L) at a time. If more than 48oz (1.5L) is needed to treat phosphate level, be sure to clean or backwash the filter between treatments.Important: Retest water after each completed treatment. Repeat until phosphate level is below 100ppb.NOTE: Algae must be treated prior to testing and treating phosphates. Chlorine must be under 5ppm before testing for phosphates.

**Q: Is the Extra Strength double the active ingredient as the regular or less?**
A: I have no Idea.  I use the highest strength.

**Q: can i use it in saltwater pool?**
A: Absolutely.. my pool is saltwater

**Q: what id the mixing ratio for this product, how much to treat 30,000 gal? testing a7 2,000 ppb**
A: Because of the nature of this product, it is a solid in suspension, and it WILL deposit on your filter and clog it, I have found that using greater than 16 oz per 100 sq ft of filter is not effective.  Above that level, whether used as directed (poured in the skimmer with pump on) or dispersed in the pool, your filter flow will decrease too much too quickly for the product to work.  So, try that dose, according to your filter area, and run your pump for at least eight hours a day for a week or 48 hours contiuously and then retest.  You may need to clean your filter and then re-treat.  Don't clean your filter before using, it just makes it that much harder to get off the filter (if cartridge) when you're done.  Remember to shake the product up well before measuring.  Also the cup on the lid is exactly 4 oz when measuring.  Hope this helps.  It's a great product with weak instructions.
