I'm using the 10 ml sample as per the instructions. That's a slightly different way of achieving the same thing. When it turns crystal clear I stop. Yes I can add one more drop to confirm crystal clear is crystal clear and subtract one but I only did that a few times because after it's...

I was talking about the FAS/DPD chlorine test. Best I can tell that is supposed to be accurate to .5 ppm The end point of the FC test is when the solution turns completely clear. Is that what you're asking?

Obviously I was repeating the test over and over because I was unable to get consistent results. If you just run the test once and accept the results how do you know its repeatable with trying it again? If I had just blindly waited till the morning and run the test once more I would have...

I know what you mean but if the results are not repeatable then the data you're getting is not all that accurate. It puts you in the ball park which is good enough, but then again all these other kits I have also put me in the ball park and are also just ok. I specifically purchased the TF-100...

Not to encouraging. I just bought one of those.

Yes I found upside down was the most consistent way I could get it and very minimal pressure. If it is indeed doing different size drops each time how do I fix that? or how do you get around that?

So my pool had turned green while I was out of town and it was recommended that I perform a SLAM and then use the TF-100 kit for accurate results to complete it. Well I followed the basic recipe and bumped my FC levels up according to the FC / CYA chart and within 6 days it was crystal clear...

Thanks for the tip. I just looked those up, seem pretty decent.

Yes I pulled the basket out for the picture. I saw those winterization plugs when googling but it looks like it would stick up some and prevent the basket from going back in place. It seems like they were be an actual plug for unused holes. I'm not the original owner so I don't know if the...

I had found these type ball valves that look like once you PVC weld the ends you can swap out the valve with orings and threads. So if they go bad over time it should be an easy swap but if that's the nature of ball valves and they'll always do that then I'd rather find something else...

Thanks found something similar here: https://www.pentair.com/en/knowledge-base/pool-spa-equipment/pentair-pool-calculators/pool-volume-calculator.html I've also been reading links on chemical tests to figure it out. Here's one example...

I do have multiple test kits although could use some higher reading chlorine tests. The winter was fine, crystal clear water, not much to do except about a cup of muriatic acid a week. The summer hit and the pool started to get a bit cloudy and I noticed I have to add a cup of muriatic acid...
