You've still got something eating FC. Likely remaining algae. Keep at it !

Ok, so here's my dilemma. I'll get home from work tonight about 4pm, and amazingly I don't have anything going on (no baseball practice, no dance, ect!). I've got a box of DE that's itchin' to get into my filter! I'm hoping to give my filter a deep cleaning when I get home. So, here's my questions:
1. Do you think my pool is past the phase of killing the algae and I'm mostly just waiting for my sand filter to clear it (judging by my photo progressions)? Is now a good time?
2. Is an evening long enough to watch the filter to make sure it doesn't clog up?

In your last pics the first one looks better. Was it the latest? Curious, but either way you are probably close enough for DE if you can watch it. You may plug off pretty fast, or at least noticeably so....so keep a sharp eye on it.
Whatever you do, don't slip below SLAM value yet. You aren't close enough to risk that.

Pool is looking great! I would say if your numbers are holding better that algae is likely gone. You can do DE in an evening, but I would backwash before going to bed. Don't do a deep clean on the sand filter as it catches more when the sand is dirty.
I assume you're talking about the pics I posted this morning? They were both taken this morning before I came to work.
Ok, just different angles then. You're getting close, and you can try the DE, but repeating the FC level, keep it up there.
My FC was 15 last night at 9pm (shock level of 12). I added about 30oz of bleach to raise my FC to 20.5(ish), as it's been dropping around 6ppm overnight, and I didn't want to go below shock. I went to bed, and didn't retest to see how high it actually got.
This morning FC was 17. Basically an OCLT although not really trying.
Ok, you are still losing a good deal overnight. You have a little way to go before you're done then.
I believe this is the point where POP runs thin! It's getting fairly clear, just finish already! dang!
Yep, and this is where people somtimes slip up and think they are done. POP...you have to find a little more...just hang tight.
I've got a couple things:
1st my filter runs clean at about 10psi, right at the top edge of the green indicator on my gauge. 11psi starts the yellow area. When the pressure in my filter hits 11 I dramatically lose flow out the return. I added the DE yesterday afternoon, and monitored the pressure. As expected the 1 psi increase from adding the DE sent it into the yellow and greatly restricted flow. Since I knew it was due to the DE I allowed it to run that way for 30 mins to 1hr while monitoring the pressure.At which time the pressure had gone up to 11.5-12psi. So, is DE just not in the cards for my filter? or do you think a deep cleaning would lower the pressure?
2nd, I back washed two times last night. Both times after I did so, then rinsed, and put it back to filter a stream of tan(ish) brown came shooting out my return for about 5 seconds or so. I never see anything coming out when I'm just running filter mode...
I know this isn't normal, but I don't know what it could be either...

That is not normal. Maybe you should deep clean. I have the the same filter just the 2800 gph and my clean PSI is 5
Deep clean might help, might not. You might try backing off on the amount of DE first, but really the filter is doing what it should it sounds like to me.
I would say either not rinsing long enough, needs a deep clean or there is something broken in there.
Sorry, Lisa is onto something. You should not have stuff shooting out. Did you BW and rinse well? If it keeps doing it, deep clean it. I rushed my answer and skimmed right over the junk shooting out. Sorry about that.
The second time I back washed, I let it rinse for about 1 minute. The previous time was about 30 seconds.
Is that correct? Should it be longer, how will I know when it's rinsed enough?

I backwash for about 1 min, rinse 30 second or so then repeat the same process. You can see the water get slightly clearer as you rinse.
I'm not too terribly concerned about something being broken. It's obviously still filtering. I'll probably try to deep clean it this weekend, and see if that helps. If something is broken, then I'll probably just deal with it this summer and fix it when I close the pool. Since it only happens after I back wash/rinse. Theoretically, if I keep my pool all sparkling then I won't need to back wash very often!
