Ultima Nano-Phos Tablets, 8.8 oz Tube, 20/Case | 27832A

Ultima Nano-Phos 27832A is a tablet phosphate remover for pool owners managing elevated phosphate levels.

Each tablet lowers phosphates by up to 440 ppb in 10,000 gallons of pool water. For an initial treatment of high phosphates, backwash or clean the filter first, then place the tablet directly in the skimmer basket with the filter running. Tablets dissolve within 60 minutes. Afterward, re-check filter pressure and backwash or clean the filter again if it is needed. Phosphate levels should be re-tested after 48 to 72 hours at a local Ultima® pool dealer.

For ongoing maintenance, add one Nano-Phos tablet each week and run the filter a minimum of 8 hours per day. More tablets may be required to hold phosphates at an acceptable level, depending on how severe the problem is.

Each package contains 5 tablets.
