Is high TDS in pools a problem? It could be, but in most cases it is not. It depends on what constituent particles are making up the high TDS level. Chlorides and sulfates can cause the most problems, reducing chlorine efficacy, giving water a dull appearance and allowing algae to bloom more easily.

What is a good TDS level for pool?

Ideally, your TDS level should be under 2000 ppm. When it gets higher than this it can decrease the effectiveness of chlorine while also causing skin and eye irritation to swimmers and metal corrosion of your pool equipment. Cloudy water and scaly deposits occur more easily.

How do I lower the TDS in my pool?

Probably the easiest and best way to reduce a pool’s TDS level is to drain it and fill it up with fresh, unsaturated water. But hold on, before draining, make sure there are no other secondary issues responsible for your pool problems. Pool circulation and filtration changes as time goes by.
