    Cannot get accurate results out of TF-100 chlorine test for the life of me! What am I doing wrong?

    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...

    Cannot get accurate results out of TF-100 chlorine test for the life of me! What am I doing wrong?

    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?

    Cannot get accurate results out of TF-100 chlorine test for the life of me! What am I doing wrong?

    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...

    Cannot get accurate results out of TF-100 chlorine test for the life of me! What am I doing wrong?

    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...

    Cannot get accurate results out of TF-100 chlorine test for the life of me! What am I doing wrong?

    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?

    Cannot get accurate results out of TF-100 chlorine test for the life of me! What am I doing wrong?

    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...

    Dead end pocket on Skimmer - how to plug it?

    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...

    Need better flow valves

    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...

    Dead end pocket on Skimmer - how to plug it?

    The bottom of my skimmer appears to have two ports where plumbing could be connected. The right side is plumbed to the pump / filter. The left side is just a dead ended hole that fills up with debris, dead bugs and junk that sits there and rots. The only way to clear it is to take a shop vac...

    Need better flow valves

    Hey Guys, I got this pool with the house and really need to improve the the flow valves. These look like standard valves from Lowes or Home Depot and they'e all broken and so incredibly hard to turn. You have to get a massive set of plumbers pliers on them and fight them like the incredible...

    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...

    Trying to figure out how many gallons my pool is?

    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...

    Trying to figure out how many gallons my pool is?

    Hey Guys, I purchased this home with a pool and trying to figure out how many gallons it is. My local pool shop (pinch a penny) had it in their computer as 10000 gallons and also 14040 gallons and they didn't know which it should be. With it set to 14040 gallons my stabilizer tested 50 and...
