So, I had not been SLAMing. Just testing and adding liquid chlorine, and if anything it seemed like the general rate of chlorine required had declined from the peak in the summer. Just tested and confirmed the FC level is not dropping quickly at all. @Jennilhoo - Been many years, but do you...

Moved from here. This is a great thread and seems entirely applicable to my situation. I'm attaching some photos of I'm observing. I vacuumed everything up last night, and this morning there seems to be a small amount that's accumulated. I'm going to try: Checking the ladders and lights for...

So, this beginner post seems great... I didn't read it all just now, but I've either read the same post, or a dozen other similar ones, and I'm fully sold. I'm an enthusiastic app user. I'll admit, when I was first told about this site as a very new pool owner I gave a passing thought, but...

FYI, I've replaced my 820. See my initial impressions here - Pentair 930 Robot Pool Cleaner - First Impressions

Dropping some notes in here to capture my perceptions of the Pentair 930 (aka Doheny's Mercury = Dolphin Active 30i = Dolphin S300i = Dolphin Triton Plus (2017 and Later) = Pentair Prowler 930 = Dolphin Proteus DX5i). Previously I had a Pentair Kreepy Krauly 820 Prowler. I purchased this with...

I'm wondering if anyone has any debugging advice here. I have the Pentair Prowler 820 (from what I read "Dolphin Nautilus (2016 and Prior) = Pentair Prowler 820 = Dolphin Quest = Dolphin Thunder 10" ). It has run well for about 5.5 seasons. Up until this past weekend it was fine. Now it...

Interesting.... I can see already cloudy water skewing the results... interesting to hear what the pros think too!

UPDATE: * Tested my FC level about 2 hours ago with my home kit and there was zero chlorine. This was after adding ~2x my normal amount 4.5 hours earlier (2.4L). This freaked me out big time, based on the replies above. The replies above made me worry I was actually very wrong about "the...

Thanks for the helpful (and funny!) responses.... I *think* I can relax my "dot scrutiny" enough... more of a "glance" than a "stare".... if that's the case, maybe I'm way too high on CYA. Going to head to the pool store for some chems and a test...

TFP Friends - I think the key question I have here is whether my black dot has disappeared (see picture below)... I have other sub-questions I would love to hear feedback on. If that dot has disappeared, then I'd say my CYA is around 40, which I believe is too low and might explain how much...
