PH is 7.7 per my new PH20 pen. What a cool tool. Never knew it existed!

not to derail my own thread, but curiosity got me and I took the light out. The green snot like junk that came out of the housing was disgusting! Anyway, the gasket looks pretty bad. Im going to run to the local pool store to see if they have the LED that I want and replacement gasket. I did...

I should have done the bulb swap before now... I dont want to drain it anymore. I bet my water bill will be $1000 this month.

ok, now we're making progress. First CYA was a 2:1 dilute - tested between 40 and 50 repeated non-dilute and got between 90-100. FC is 19.... I only have my SWCG set to 20%, and leave my pump running 24/7... I guess turn the SWCG back to 10%?

Correct - I drained it down between 1/3 and a half - three times now. The first time I did it was several days ago, then I did it again 2 days ago, let it mix for 24 hours and did it again. I just turned the pump to the higher setting to mix it better. Will test again in a few hours.

Im sure it was WAY higher when I started. I just started doing the diluted test today.... When I first tested I couldn't see the dot after only a few drops. It was CRAZY high in the beginning.

Here's my CYA test method - I put 7.5 of pool water in the bottle. I fill to 15 with tap water I drain off to 7.5 I fill to 15 with R0013 I cap and shake - wait 30 seconds and shake once more Then I go outside with the CYA tube at waste level, back to the sun, then fill the tube until I no...

One would think.... but at this point - I've done a 100% exchange and only seen about a 20 PPM drop....

I have no clue. I have no experience with pool lights.

Im doing another exchange. It just dawned on me.... This is a great time to switch the light to LED. Any of you have a recommendation for a color eld swap?

I'll order one of those - in the meantime, I'll test the water with my skin. lol

hmmm, the PH test that comes with the FT pro isn't accurate? Is there a better than other pen to purchase?
