Why is there no chlorine in my POOL LAB Water Filtration Systems pool?
- ZZachary OrtizAug 17, 2025
If there's no residual free chlorine in your pool water when using POOL LAB Water Filtration Systems, ensure the chlorine output is set to 100% until the chlorine level is restored. Also, increase the system's running time, aiming for at least 8 hours daily during summer. Sunlight can also affect chlorine levels, so maintain a stabilizer level (cyanuric acid) between 40 – 80ppm and use a pool cover when the pool isn't in use. For heavy pool usage, manually add liquid chlorine during peak demand. A high total chlorine reading (different from free chlorine) may also be the reason, in this case shock dose the pool with liquid chlorine.
