Nite,
Sorry to hear this hasn't cleared up for you yet. We do see pools where this happens every now and then. There's a lot of speculation about why this happens but nothing proven yet that I know of. My personal belief is that it's most often caused by not staying at SLAM levels long. If you have SLAM level only for an hour or two that means the process is going to take a LONG time. Looking at your logs seems to validate this could be your issue. With your schedule it's not easy to do unless you go waaaay over SLAM levels and this is never recommended as it can cause damage. Is there any way you can get a day that you can test and adjust every couple hours? This might be what it takes. Also is it possible you are cleaning anything in or close to the pool with a cleaner that contains ammonia?

Chris
I did that last Sunday, I was off from both jobs. Also on Monday I was working from home for the first job, so I was checking and adjusting every hour until about 5pm. I will also being working from home todaay until about 5pm, so checking and adjusting every hour.

Can you share a picture? Could it be a closed return or water feature (any extra valves from the filter/pump)? Are they on the wall or in the floor?
Pics added to the post, They are on the wall in the deep end. I have 2 valves come from the return. 1 is the jets and the other is my makeshift waterfall. There is no suction or return from them with all valves open.

Instead of buying something new (not that you couldn't use it), can you stick a hose in there and see if anything flushes out?

Good idea, gonna try that now. I did however pull the trigger on the drain cleaner. I also grabbed a mask and some dive weights. All will be here tomorrow, planning some deep cleaning underwater. I will unscrew that drain cover and get under that thing now too.

That should help. If you can get to the point that you see much smaller decrease in FC loss with the same time period it is best. Once you get to this point you can increase the time between tests. The SLAM process will work with fewer FC checks just can take a LONG time as you are experiencing. Your schedule makes this difficult and I wish there was an easier way but I don't know one. Frequent brushing and tracking down any hidden pockets also helps but I think you're already doing this.

I had the same concern when I first started with TFP because of extreme amount of business travel. Fortunately, I never got to the level you had so my occasional SLAM's have been extremely short. 1 day max and never cloudy or discolored pool. Only a local spot or two of algae when I got a little lax on FC level. That doesn't every happen now with salt. May be a good option for you in the future.

I had that aha moment today that I was looking for. I am hoping that was all of it, but I will still be pulling the main drain cover off tomorrow and scrubbing under it. Once I get the mask and weights delivered. I have never been soo happy to find algae...lol
That would do it! Good job!!

Nite,

Great catches! I'm sure that's a lot of your problem and wish I had mentioned all the grout lines previously. I have a similar issue from time to time. We live right next to a wetland preserve better known as an algae farm. When any green/black appears in a grout line in the above water line or coping I scrub vigorously. If you can't get it use an old trichlor puck to force some into the crack and let it sit a little while then scrub off. Works like a charm.

If you're planning to scuba down with weights you can just rent them at a scuba shop. It's very dangerous to add weights if you're not in scuba gear. Even worse by yourself. Safety first!

So great news on finding that algae. So as you scrub the cracks at your waterline here is another idea. Get a spray bottle and fill it with LC. After you scrub the cracks, spray some LC directly on it to really kill that stuff off.

I am a certified diver, just haven't been out in like 10 years. Sold all of my gear years ago. The pool is 5' 3" at deep end, and only getting 5lb ankle weights. I am not worried about being able to reach the surface. Will just be doing this as a free dive, no tanks.

No, maybe some old returns that have been disconnected or old features. Do you have any water flow at all from or to them when the pump runs? I'll ask a few more experienced people to weigh in on this. @ajw22 @Jimrahbe @Texas Splash please see post 267. And ideas what these are for? OK to plug?

It does not connect to nothing, no return or suction from it. It seems to be 1 "U" shaped pipe. Something like this, when I shot the water in 1 end, it came out of the other. With a green puff.
