Frequently Asked Questions About OnGuard Pool Start-Up Kits
Can these kits be used in saltwater pools?
Yes. OnGuard start-up kits are safe for saltwater pools. Turn off the salt system during treatment and restart once water chemistry is balanced.

Most pools are swim-ready within 24 to 48 hours once chlorine levels return to the recommended range and the water is clear.
Do I need additional chemicals?
Our kits cover the basics, but you may need to adjust pH or alkalinity after testing your water.
