Can you post a link to this post? I'm also considering both the Scuba S1 and Seagull Pro.

Understood. My comment was more theoretical from a background in water/wastewater treatment.

Another thing to consider is more Hypochlorous Acid (HOCl) is present when Chlorine reacts with water at lower pH. A higher pH will result in a greater percent of Hypochlorite Ion (OCl¯), which has a lower disinfection ability. In sanitizing water, HOCl is 80-100 times more effective as OCl¯.

I have the latest version from the Apple App Store and my history ported successfully. The only issue I've found is that the PH target defaults to 3.

I have a new cartridge filter enroute to replace my DE filter and a new VS pump when it comes off backorder. I know the cartridge filter is going to have a different inlet/outlet configuration and the height of the filter fittings will change. Currently, my DE filter has a push/pull valve that...

Just curious. What did they quote for the backorder?

CSI and LSI are more influenced by PH, CH, and water temperature. Using your readings from the first post PH 8.5 TA 140 CH 100 CYA 35 your CSI is 0.46. I assumed your pool water temperature was similar to mine in Plano 67.1 degrees F. Lowering your PH to 7.8 would result in a CSI of -0.23 which...

First of all, what test kit are you using? The recommended test kits don't report TA in increments of 5. Here are the TFP recommended test kits. https://www.troublefreepool.com/blog/2019/01/18/test-kits-compared/ Your fill water does not have CYA. My advice is not hyper focus on Langelier...

Yes, you can either use a 2" x 1 1/2" reducing bushing or a 2" x 1 1/2" reducing coupling. Both are common and easy to find at your local big box hardware store. I don't know where you're planning to order the pump from but I read on another thread that there is a long wait on these from the...

This article does a good job "dumbing" down the reason why FC/CYA is so important. Using your pool store results, which shouldn't be trusted, your range of FC would be 8 ppm - 14 ppm and if you ever needed to SLAM you would need to increase and hold that at 42 ppm. It would take roughly 8...

Received my K-1766 today and the pool testing 1,000 ppm. I’m considering adding salt to improve the water feel.

To answer your first question. On the screenshot you provided there is a toggle to turn on SLAM option and the recommended SLAM Target FC will be shown. No additional step needed to use the FC/CYA tool. Generally, your process looks good. Here is a link for the official SLAM process. Don't stop...

I've been chlorinating my pool using liquid chlorine since taking ownership last year. Is there any reason to purchase a salt water test (K-1766) to compliment my K-2006 test kit?

The black dot never disappeared would indicate a low CYA and not high.
