all my numbers are inline with TFP. starting to get the hang of things. I am still struggling with the CYA test. My test using the TF100 is consistently coming in at or near 30 maybe slightly under. hard to say. I took the water to the LPS (just to see how my numbers match up) and to return chemicals. Their CYA test showed 45. 8 days earlier their test showed 23 and I was still at 30. However, since their test and prior to starting TFP I did use about 8 -10 pucks before i could find the liquid chlorine. The pucks would add stabilizer but would not think to go from 23-45. is there that much subjectivity? Pool Math says to add about a pound of stabilizer that would bring it up to under 40ish. is it better to run towards the low range or a little higher.
Also, i was able to return all pool chemicals (almost $350 worth) except for Bioguard Optimizer. I have read that this product is ok to use and the pool store would not take it back. They gave me a lot of grief and claimed that there is no way to maintain the pool just using chlorine and maintaining TFP.
In any event, would appreciate some feedback on the CYA and optimizer. My Borates per the LPS are 9.
Pool is clear as it has ever been. Thanks
