#Free chlorine is too high free
Very low salinity levels may bring down your available free chlorine to 0 ppm, which will almost certainly encourage algae to thrive.Īpart from low salinity levels, low free chlorine can be caused by: If your free chlorine falls below the recommended levels, you need to measure salinity and increase it if it is below the recommended levels before even thinking of adding chlorine shock in the pool. Low salinity levels reduce free chlorine. The recommended free chlorine levels should always be between 2-5 ppm, depending on the level of cyanuric acid in the pool as indicated in this chlorine/CYA chart. Monitor free chlorine levels by testing and adjusting on a regular basis. Ensure that you add these substances slowly in increments and allow the water to circulate for 4-6 hours before swimming. To increase pH: Use alkali such as soda ash.To reduce pH levels: Use muriatic acid (liquid hydrochloric acid) or a dry acid such as sodium bisulphate.High pH levels in a saltwater pool lead to the formation of calcium buildups and you need to measure your pH regularly to avoid white flakes or calcium scaling. Ideally, the recommended levels for pH should be between 7.2 and 7.6, with the most ideal or optimal level of 7.4. Here is a salinity calculator that will guide you on the correct amount of salt to add to your pool to avoid excess salinity.Īn ideal pH level is necessary to enable chlorine to function effectively and kill harmful bacteria.Keep in mind that salt levels will be recycled during the process of chlorine production, and you may not need to add more unless the level falls way below the recommended range. The only way to reduce salinity is by draining the water and refilling with fresh water. Make sure that you don’t add too much salt into the pool.Cooler geographic regions will experience reduced water conductivity, and if you are taking the reading of salinity from the generator, you may get a much lower and inaccurate reading, so you need to be extra careful not to add too much salt.
#Free chlorine is too high generator
You must either test the salinity level before adjusting it or use a chlorine generator that monitors and displays the salinity reading. Chlorine generators operate well with salinity levels between 25 ppm.This is the first thing you need to take into consideration before adding or reducing salt in your pool. Different chlorine generators require different salinity levels.Saltwater pool systems operate efficiently only when salt is in the right concentration.Test and Adjust Salt Concentration (Salinity) I would add 1 case of liquid chlorine from a pool supply store – I’d be afraid anything from a big box store wouldn’t be strong enough.Īlso have your TDS checked – if they are too high you will need to drain and refill some water – it doesn’t happen a lot but if your main sanitizer is stabilized chlorine tablets and your water can’t absorb any more chemicals it will cause the bind as well.1. You need to super chlorinate to break the bonds – though if you have a high TDS Total Dissolved Solids reading that could contribute as well. The used chlorine has locked all available chlorine and is stuck together with contaminants. If you have chlorine locked – it would cause the readings you are getting and for the smell to be present.
