Lowering Cyanuric Acid In Swimming Pools In Oregon
The Puripool Process can and will remove excess CYA (Cyanuric Acid) while the rest of the pool is processing and lowering calcium, TDS, salt, bacteria, viruses, phosphates, etc. In the Grant’s Pass area, we get called out to primarily lower CYA in areas where the concern over calcium removal is not the driving force. We know of nothing that is capable of removing excess CYA as quickly or efficiently as a Reverse Osmosis pool filtration because the only other option is a drain and refill which takes several days!
What is Cyanuric Acid?
The purpose of CYA is important for your swimming pool especially in regards to its relation to chlorine. In an outdoor pool with no CYA, chlorine is consumed within the first 2 hours of sunlight hitting the pool. CYA serves to protect the chlorine and allow it to stick around longer. However, too much CYA will bind over the chlorine and will not allow it out to work and this is where the problem exists. We often hear that “I can’t keep chlorine in my pool” when it really is present but unable to break through the barrier of too much CYA. In the end, there is a direct relationship to the amount of CYA in a pool and the proper chlorine level. The multiplier to figure out how much chlorine (in ppm) you need is .075. In the case of a pool with 50 ppm CYA (what is recommended), we would take 50 times .075 to get minimum chlorine residual of 3.5 ppm (we always talk about free chlorine here). Whereas, a pool with 100 ppm then would require a minimum of 7.5 ppm free chlorine as 100 X .075 = 7.5. Oftentimes in our industry, we hear that 2 – 4 ppm free chlorine is good, with no regard to the relationship it has with CYA. With this simple example, you can see that a pool with 100 ppm CYA and only a 4 ppm free chlorine residual is asking for trouble (algae)! You must either lower your CYA level or increase your free chlorine to keep a safe and sanitary pool in this case. One other example which should drive this point home is what happens when your CYA is 200 ppm and higher? Trust us this happens! You would need a residual chlorine level of 15 ppm which is hard to maintain. So what do you need to do?
How To Remove CYA From Your Swimming Pool
The simplest way to lower CYA in your swimming pool is using Reverse Osmosis (RO) filtration or what we like to call The Puripool Process. Oregon Pure Water utilizes RO filtration on residential and commercial swimming pools. With our service, there is no need to drain the swimming pool and we are able to give you the best water quality to swim in. We have had a lot of success processing pool water and would love to give you the opportunity to experience this service. Please contact us today to learn more!
