I find it very therapeutic to open the pool and to do a better job each year… A little bit smarter… this form has helped me a lot. I often think about ways to contribute back to the forum as I’m cleaning, scrubbing, skimming…learning.

Just did the full chem test.... TA=30 (surprised....last winter it didn't drop so much) CH=150 (I don't have any calcium chloride in stock right now) CYA= 20 (Actually, the dot couldn't be seen 2/3 way from 30 to 20, so CYA more like 23) FC 0 PH 7.2 Tested PH again PH=7.2 (changed test kits...

Opening green pool for season....just used all my acid an the pH did not make it to 7.2 (3 gallons of the Green Eco Crud). It is now 7.4 Can I start my SLAMING at this level. I want to avoid running to the store for Covid 19 reasons. My slam typical takes a week, so I can re-stock...

Added .75 gal of Muric Acid on a PH reading of 8.2 in my 20,000 gallon green swamp/pool as first step to open.. Waited 1 hr. Remeasured, same result (8.2 or higher), so added another .75 gal WRONG! That shot it to below 6.x (whatever the low end of the scale is....which is not accurate as...

So I lost my pump motor and have a new motor on order. Won't be able to fix is for a week or two. Pool chemistry is perfect right now, and pool clean....but what should I do knowing there will be no cleaning or filtering for a few weeks? I live in the northeast, so water temps are cold...

Thank you. I have consistency from test to test. I get the same number. But the accuracy as described in the pool school notes applies to test equipment accuracy, NOT user error. What the note from Pool School says is: The precision of the test, when done correctly, is around plus or...

Thank you. Maybe I am being stupid, but if my CYA test reads 30, and it is + or - 15 PPM per the pool school notes on CYA testing, then my actual CYA is 15-45 PPM. Now FC targets are are a function of the CYA, so the FC targets are all over the map.

I am converting to TFP. Got my test kit. My water is fine, I completed my SLAM and now looking to just maintain. So I had the store test my water just to very the TF-100 test kit results and the CYA is significantly different.:( Here are the results: Store TF-100 FC 6.18 6.5 CC 0...

So I am new the forum, but I now have the religion (and a good Kit). I am only at my pool on weekends (pm Friday-monday a.m.). I am slaming now, but not finished. How should I leave the pool for the week? Water is clear, but still consuming chlorine. I do have a tricolor feeder, but...

Enclosed is a photo of the test result referenced above. This is a stair/shelf in the deep end about 15" deep. The 3" puck was placed at the 2:00 position on the left most square. It is now white. The Vit C test was done at the 3:00 position of middle square. No change. The OCLT did not...

I just got my test kit yesterday, I am no longer blind! I am at the near end point of SLAMing my pool and staining still exists over 1/2 the pool surface. The water is now crystal clear and I can see the plaster perfectly clear, including the 12' deep end. The staining is a brownish/tan stain...
