I really appreciate the links for the iches but I am looking for the actual light housing that is waterproof and protecting the LEDs inside the housting (bulb). The niches will be useful when I find a 10" LED bulb housing that is empty or I can cannibalize and use my own LED pixel module. eg...

I am rebuilding our concrete bulkhead against a water canal. I'd like to install multiple (around 12 so far) 10 inch underwater LED pool lights evenly spaced along the wall. I'd like to avoid spending almost $1,000 each for a Pentair LED pool light. All the videos I have search use an existing...

And of course start logging your results with PoolMath app. It will help you get a feel for chemicals and the test results over time.

Before I really went down the TFP rabbit hole, I was maintaining pH roughly 7.5. When I read about scale build up in the SWG, I opened it up for the first time after 10 years, and there was no scale build up. I have never acid cleaned the cells, I didn't know I needed to maintain it. Now that I...

Found the CSI calculator you mentioned and solved my issue. Thank you. Interestingly, even though my pH, salinity and pool temp may shift a little during the day, there is minor changes in CSI calculation. I think I had a little OCD trying to get realtime CSI. Now I do and its just not impactful...

Pool Math is a wonderful tool that calculates CSI for us, which is awesome. However I am trying to calculate my current CSI realtime. Generally my Alkalinity, CYA, Calcium Hardness are fairly static between weekly testing, however pH, ORP, DO, water temperature, etc. vary widely throughout the...

Tracking Min, Target, Max. I realize many of these are indirect markers and some argue worth and accuracy, however I and it seems many other use a variety of probes that measure these and would be beneficial to monitor these for trends. Use case: as a home owner with a pool, I also travel for a...

I've had a 18k SWG pool for about a decade. For a few years, I 'had a system' with preset chemical adds (1 lb CYA, 8 lb borax, 1 lb calcium, 1/2 gal muriatic) to each 40 lb bag of salt necessary. It kept things pretty inline with strip tests. Over last few months we have had more rain than...
