Hi folks! We bought a house with a pool in December and I have spent the last several months trying to understand how everything works. I think I finally have a handle on it...or at the very least an understanding of what things are supposed to be like. For a while I couldn't understand why I was burning through chemicals so fast...then I discovered that we were overfilling the pool so all of the chemicals were getting flushed down the drain. Once we got that situation resolved we still struggled to get the pH and TA under control. We finally tested our tap water and found that the TA was 310! Needless to say we go thru a lot of Muriatic Acid around here.
Now on to my real frustration. I finally felt like I had a handle on chemicals and this morning I took my water in to Leslie Pools to just to confirm my test. I use the TF-100 test kit (purchased this spring...kept in a utility closet off my kitchen so away from light and heat) and the Taylor Basic pH and chlorine test. My results were as follows:
Salt: 3000 (per Aqua-pod Reading) Test strip: 3550
I took a water sample in to Leslie's within 30 minutes of my testing and the results that the clerk got seemed to be very different. (I should say I hate this particular location as every time I go in they seem to want to sell me EVERY chemical they have. When I told the guy I already have everything I just wanted to confirm test result he could barely contain his irritation long enough to check out the $4 purchase I was making.) His results were:
He of course wanted to sell me Muriatic acid and informed me I needed to add 3 pints as well as 25 oz of hardness plus and 8 lbs of CYA.
The last couple times I had this location run samples they wanted me to add lots of stuff as well and MY pool service guy told me to hold off on everything but the hardness and do one thing at a time.
I decided to take another sample to a different Leslie's. This sample was taken about 2.5 hour later than the first but no chems have been added since yesterday. these were their results:
I should say both Leslie locations showed phosphates at 300...although only the first one tried to sell me product. The other location was just concerned at this point with the CH and CYA levels.
So here I sit a bit baffled as to which results I should use. My results have my pH and TA pretty much where I want them and I was hoping to start adding borates to help maintain them since I need something to buffer it when having to add fill water. But 80 seems a little low for TA and 7.8 is higher than I would like it. Especially because I seem to be having a scaling problem as well.
I added 2 lbs of CYA yesterday and intended to add an additional 2 lbs today but was told to add the CH first...but that I could add the CYA 4 hours later.
All this said...I am extremely confused on whose testing results I should be relying on to get and keep my pool in the best possible condition.
Any suggestions or advice would be much appreciated!
