are you sending a private message to chemgeek yet? The bat phone will be ringing shortly.

I will let Richard explain you this phenomenon if he will feel right to do so.

your so butt-hurt it's funny

I am the best little pool man under sun!
I know everything there is to know about CYA.
I will be 18 in the fall an I have been doing this for as long as I can remember.

I'm a bitter old retired man who takes care of his own "once algae filled" pool and have now learned how to take care of it with out getting algae. So if you need any help at all please feel free to message me with anything related to a pool in the future.

If I was dealing with an Algae filled Pool I could care less about CYA as long as there wasn't much in the pool. In fact less is better until the algae is gone and you can start to try and balance the water properly.

CYA is to protect the chlorine from the sun. O ya, Salt guys like to add it even to indoor pools to help stop the salt system from eating the pool because these set and forget systems like to build chloramines and then of course have to overproduce chlorine to compensate which of course is pumping way more electricity into the water and way more acid. Of course you don't actually read a lot more free chlorine in the pool because it gets wasted trying unsuccessfully to eliminate the combineds. The CYA in the water will help to tame the often very high levels of chlorine in the water.

My theory tho, and I'm sticking to it LOL

Ok you 2, carry on!

To back up Czechmate, I had a serious Algae issue in my pool, got it tested and results showed my CYA at 100 and my FC at 0. So CYA does nothing but keep Chlorine in the pool longer. also, I am having the same issue with my filter getting high pressure after a short run period. I guess I will just have to keep taking the grid out and spraying that sh!t out. or run it with it out to test that.

Pool chemistry is not a rocket science, but it is still part of a chemistry science. So until you fully understand it, oversimplifying the individual roles of a pool chemical will cost you money. Sometimes it can be a great deal of money. That is why understanding what major chemicals keep your CSI in acceptable levels is so important. PH,CH, FC,CYA play ALL very important role.
( Do not underestimate the role of water temperature either. What is OK in the winter, may become dangerous in the summer).
Look it up in POOL CALCULATOR website and learn it. As it will slowly become a routine, it will become much easier to maintain not only your water, but give you a piece of mind in preserving your investment.

What if you remove the filter and use skimmer socks to catch and filter at the skimmer. It seems as this may be a faster solution to the issue (rather than back washing so frequently and loosing water and filling).
Any comments would be welcomed. Thanks.

I continue to have the same high pressure issue. I have followed all the above steps including taking out the filter elements and cleaning them. This is the first time this year with this particular issue.
