I'm happy to report when the FC dropped to 22 the CC dropped to 0.5 just as you predicted!

Note on the CC, it has been 0.5 three times, 1.5 twice, 1 four times (I wasn't always testing for it) during the SLAM but the 0.5s were when I was fighting to get the FC up to SLAM levels. I'll continue the SLAM through today and take a final OCLT tomorrow and they do as you suggest. Thanks...

No, no cover.

Thanks for your honest feed back Dave. I thought my chlorine use was insane as well and my pocket book confirms this. I'll continue the SLAM though this week as the consumption has leveled off (adding cups of chlorine not gallons. woot woot!). FYI the pool passed the OCLT but CC is still 1.

I was thinking the same about it not coming out, unfortunately the algae is on the inside of the light, not outside. :(

Here is a picture of the light with the chip highlighted. Notice how small the light is compared to my pebble size. I think it's called a filament light? It's old and not very bright and we don't use it. https://photos.app.goo.gl/gAVeBhoFZB3ZUURG9 Paul

Unfortunately there is no viable screw. I was just thinking about caulking around it with silicon. Thoughts?

New update, we swam today for the first in over a week so I closely inspected my small pool light. There is a chip on the edge and I can see green stuff inside it. Looks nasty. Could this be my problem child? If so what do I do about it? Paul

Ok so I crunched the numbers based on my log and my target FC of 28. Since 8/6 to today the average daily FC consumption has been 24. Here is the break down. 8/6: 50 8/7: 46 8/8: 33 8/9: 30.5 8/10: -3.5 (I had a net gain!) 8/11: 2 8/12: 10.5 with two readings today.

Note at the start of the SLAM I was only testing/adding chlorine 2-3 a day. I looked back at my log (only started logging on 8/6) and I had a REALLY hard time getting my FC up at the start because I want I believe was weak Walmart liquid chlorine AND massive FC consumption AND only adding twice...

Thanks Rob! I'll remove the robot. Two more thing I just wanted to add for complete info here. 1) There is still about 0.5 ppm Copper in the water from a Costco Solar Ionizer that was removed per TFP recommendation against metal in pool. 2) Last Monday out of frustration and hoping to...

Yes, I'm using the K-2006 and very comfortable with the testing methods as I've done so dang many of them over the last couple of week. I thought the FC loss while using the robot was strange as well. I was wondering if it might be because of the bags never getting 100% clean. I'll clean the...

And one more thing, I've noticed when I run my pool robot every day I loose 5-6ppm of FC! Has anyone ever experienced this before?

I do have a fair number of birds with all the trees around my pool along with the accompanying leaves, twigs, etc. This is our monsoon season so blowing dust is common. Also a fair number bees die in my pool.

Morning all! Passed the OCLT once again. Cleaned test tubes prior to testing. CC=1 again. Boo! Keep slamming?

I understand, FC is 28-30 as I've been SLAMMING. Any thoughts on my other questions?

Looks like I might have finally won the battle. Pool passed the over night FC loss test with CC at 1. Do I just keep maintaining my target SLAM FC until the CC is at 0.5 now? What do I do post SLAM? Just let the FC come down before I start swimming again and maintain the high side of the...

Here are links to the two pictures. https://photos.app.goo.gl/a3kYEeS9uNEFiVVa8 https://photos.app.goo.gl/XMo5ZisrvcR8fZgA8 Note yesterday the dude at the pool store said that it's an in-deck chlorinater.

No, it's not connected to the pop-ups, just a pipe in the can that goes down down, makes a 90 degree and ends up in the pool. I asked the company the resurfaced my pool last year and they had no idea what it was. I'm serious thinking about plugging this pipe on the pool side. My pop-ups run...

Ok so I'll take your advise and start adding chlorine 5 times a day, up from my current 3. I also took your advise and looked at a my pool to try and find where algae could be hiding. I came up with two place. 1) My pool auto fill/leveler can and feed pipe. 2) Another strange can and pipe...

Yes the co2 is automated but I have it disconnected currently. I always target the 28-30 when I add using the dosing from Pool Math, are you suggesting I add more often then the 3 times a day I have been?

Pool Math say 28 FC to SLAM so I've been targeting 30.

Hi all! Since June I've been fighting recurrent green algae growth. About to weeks ago I found the SLAM method and thought I'd give it a try. As the subject says I've been SLAMing for 2 weeks now but I can't pass an overnight FC loss test, for example last night I lost 10 ppm of FC. On top...

Are you saying when you manually tested you got results of 14ppm of Free Chlorine and pHin said it was still safe to swim? How much chorine did pHin say you had?
