ActingRemoves phosphates on contact. No waiting for it to start working.


Works on Contact. Concentrated Max+ is built on lanthanum chloride, the active pros reach for when phosphate levels need to come down fast. It binds phosphates as soon as it hits the water, and your filter captures what it removes. Formulated for professional use, sold in a 32 fl oz concentrate.
- Instant acting formula removes phosphates on contact
- Helps prevent algae growth by removing its food source
- Lets your sanitizer do more with less

600 ppb. Test phosphates as part of your routine, not just when algae shows up. Keeping levels below 600 ppb keeps the algae food supply low and takes load off your chlorine. If a test reads higher, dose by the chart, filter, and retest.
- Test phosphates regularly, even when the water looks clear
- Dose by the chart, starting at 2 oz
- Run the filter 24 to 48 hours after treating
- Clean or backwash the filter, retest, reapply if needed
Phosphates do not change how the water looks. They build up from rain, runoff, leaves, and swimmers, feed algae, and make chlorine work harder. Testing and keeping levels below 600 ppb helps stop algae before it starts.
Test first, then dose by the chart: 0 to 600 ppb add 2 oz, 600 to 1,200 ppb add 4 oz, 1,200 to 2,000 ppb add 7 oz. Over 2,000 ppb, add 8 oz, then retest and repeat. Apply evenly over as much of the pool surface as possible.
Water may turn cloudy or milky when phosphate levels are high. That is the phosphate being removed. Keep the filter running 24 to 48 hours, and do not swim while the water is cloudy. If filter pressure rises, clean or backwash the filter.
Do not swim while the water is cloudy. Once the water has cleared after filtering, and your water levels are in the proper range, the pool is ready.
No. Phosphate remover is not a sanitizer. It removes the phosphates that make chlorine work harder, so your sanitizer can do more with less. Keep your chlorine in its normal range.
