That's hard to say, I couldn't see that well when cleaning out the niche last fall and it's about 7 years old. Thank you and everyone else who replied for your help.

Your other question: I estimate about 60-65 feet of conduit. And here's a drawing of our niche.

Yes, we had the light replaced twice (this installer didn't seem to know about the ground either). It's a continuous cable that's factory sealed to the light and the only connection is at the breaker panel. I worked in the electrical industry for about 40 years, I'm confident about this one.

120V. No j-box between the light and the electrical panel, and no transformer. We've been experiencing some powdery material on the light, and Pentair said we should add the ground wire. It was left off by the initial installer. I have to hope that they installed the bond on the outside lug.

Our Pentair light niche is supposed to have a ground wire from the electrical panel to a lug on the inside of the niche. I have an electrician lined up to install the wire, but Pentair calls for 3M Potting Kit 2136 (or equivalent) to seal the connection. 2136 specifies that it needs to cure 4...

Sorry, here's a picture before we cleaned the bottom.

This thread is just to thank everyone on TFP for making pool maintenance achievable. This is our 4th pool opening, but the first since following TFP as of last August. We've never been able to see the bottom of the pool at opening, and some years it took 3 weeks or more to clear up. This...

Thanks for the info, Pool and Chris. I'm planning to add borate, but thought I should bring CYA and TA to the proper levels first. Does that make sense? I added a little waterfall fountain from Home Depot a week ago for aeration, not sure it's doing much. Not seeing TA change anything like...

I really appreciate your help!!

It seems OK, what do you think? (BTW, I hope I'm adding the images correctly)

Sorry for the confusion. I was away for the week so my wife just used test strips to keep FC level up during that time (8/23 - 8/27). All the measurements are with the K2006. About the MA additions: just before noon, pH was 7.4. My poolmath app said to add a little more than the 48 oz to get...

Those are all my tests with the K2006. So rounding, it looks like we went from 60 down to 30.

Started with TFP early this month, working on CYA and alkalinity levels. CYA was too low to measure with the K2006. Last pool store test said 17. Added 4 lbs (in a sock) and it came to 27. 4 more and it was 44. 4 more and it's up to 63, 6 days ago. No additions this week so the filter...

Talked to a service representative from Pentair yesterday. He suggested 2 things to check. (1) get an electrician to look for stray current and (2) see if the slimy gunk is white water mold. He experienced the same gunk behind his own pool light. After reading several posts on TFP last...

Checked the grounding between the panel, pump motor, and heater. Zero ohms resistance between each of them and the earth ground. The cable to the light is grounded properly at the panel. My wife took over making follow up calls and she just made a breakthrough this morning, we should see a...

I'll see if I can get the light out for more pics. No known electrical issues. The panel and wiring seems functional, if perhaps not the tidiest I've seen. Bonding is unknown. The installation doc shows the ground lug on the outside of the niche where we'd have to dismantle the pool cover...

Yes, both are zero and usually are. Sometimes we get copper after refilling or over the winter, but it doesn't stay long.

When we bought our place in May 2019, the pool light was not working. It would have been installed in 2013. It was a Pentair Amerlite and Amerquartz light niche with an Intellibrite controller. In May 2020, we made several changes: converted to SWG, installed a variable speed motor/control...
