I appreciate the feedback and info guys. Sounds like my weekly dosing for rising pH is perfectly normal.

Agreed on the pH affect on chlorine. I misspoke on that and responded above. Thanks for letting me know yours also rises that quickly. I agree it is indeed the SWG as I switched for bottled chlorine manual dosing for a couple weeks and noticed the problem went away. I always thought TA...

I may have misspoken on the PH to algae relationship. I used to keep track of this in a spreadsheet in the early years and looking back I believe I had very low CYA at the time that was my likely culprit. No water features or spill overs. I assume you're asking due to aeration of the water...

I've had the pool / house for 5 years now and while most everything chugs along fine I find I have to bring the PH down every week, actually it's every few days but I settle for once a week because sodium bisulphate is expensive. My PH is always pegged at max on test kit which is 8.2 when I...

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.
