Seeing some very fine debris leaking through a slime bag is normal, especially if it happens while you are handling the bag.
Pics coming in a few minutes.
I understand but it is an immense amount when it is barely moved. When I removed the Backwash Slime bag, I had to struggle with it for about 10 minutes because it was so heavy with water and substance. The water is really slow to drain from it and it is a huge bag.
After last nights filtering the pool has cleared a lot. I can see the bottom drain well now. I took pics last night of the cloud. Posted below. Just got back from "delivering" DH to airport. I didn't look at pool before leaving. Added a couple of hours after starting this post.......... the pool is a gorgeous deep blue now that the sun is hitting it from an angle. Sparkle is beginning to happen.
What does the water look like, in as much detail as possible: color, opaqueness, etc?
Color is beautiful blue, no hint of green or aqua. It's the fine cloudiness. See pics below. The scale has been continuing to lift all winter after AA treatment; especially evident on steps. I fought keeping the CH up since I switched to BBB last summer, because of so much backwashing and splash out. Even with all the water replaced or let out due to rain the 220 CH from yesterday's testing is higher than I could keep up during during summer and fall. I think the main issue is the calcium coming off surfaces. The cloudiness really picked up when I started using the Aquabot, which really, really scrubs floor and walls, much more than the Vero 300 ever did. Vero couldn't make it up the walls.
Please post a full set of water test results.
I started adding CYA a few days before new pump and filter installed 6 days ago. CYA was 20 prior to addition.
(I've been moving things around and I've misplaced my full TF-100 kit. I have separate, mostly Taylor reagents, that I purchased prior to ordering the kit and a separate FAS/DPD Chlorine Drop test, and have been waiting to use them up before breaking into kit; when I find it. 
)
FC - 8 @ 75 F
pH - 7.5 @ 75
TA - 60 @ 53
CH - 250 @ 53
CYA - 60 @ 53
Temp 53 F pool --- 75 F, brought inside and sat sample cup in hot water
This has been one of the coldest, longest, cloudiest, rainiest winters on record. After AA treatment kept pH right at 7.2. Sequestrate all winter. Cl never tested < 2 all winter with chlorine additions when needed. Very low Cl demand all winter.
Has the water improved over the last several days even slightly?
Yes, dramatically as of this morning compared to last night.
How much stuff are the slime bags catching and what does it look like?
It is a mix of light tan to white with some brown depending on whether I set the submercible pump on bottom of shallow end, where most of the silt settles or hang from side of deep end. Most much lighter than our normal silt. It's hard to judge just how much. Two pumps, two Slime Bags .
Why do you say there is no algae?
I've been keeping close watch on pH and Cl. Water temp just crossed into 50's a little over a week ago. It's been in 30's and sometimes in low 40's until just recently. Never had any algae all summer, fall, when did AA, or after. I would be shocked :lol: if there was any algae growing in there.
In Jan we had our "Big Freeze" with an inch of ice on pool. Water balance good prior to that and after. Even ran Vero 300 or Aquabot under the ice after I could chip a hole in ice. After I drained the pumping station for "Big Freeze" I kept water constantly circulating with submercible pumps, one on each end of pool and only stopped them when I ran the Vero 300 or Aquabot for at least 10 hours, several days a week. I went through at least 4 of the Aquabot "Nasty Bags", almost as fine as the Aquabot fine bag, and the Aquabot fine bag each cleaning cycle. Dip rinsed, three buckets, and then washed on cold gentle, a batch after each cleaning cycle. The Nasty Bags are so cheap I have a bunch of them.
No organics allowed to sit in pool, skimmer sock, Pool Skim X 2 collection bags, for much over a couple of hours except at night; constant emptying through out the day, cleaners keeping leaves up during day when needed and most nights, all night during leaf falling time. Raised Cl levels up to shock level several times when I was in a hurry and didn't measure or use Pool Calculator. This was weeks after bringing Cl up slowly after AA treatment. Polyquat 60 (type) algae control, in abundance, during and after AA treatment. Chlorine demand low, late fall and all winter.
It is highly unlikely anything is growing in it.
I have been playing with the pump some. "Favorite Most Trusted Pool Guy" (he told me to leave it alone, don't use any cleaners, let it clear before doing anything other than backwashing if needed) had pump set to 30 K 1 cycle a day but for only one 12 hr period. Clean filter pressure 7 psi. I bumped it up to 2 cycles per 24 hr period for a couple of days, 25 K. Then I set it on 4 cycles per day, 24 hour, 20 K which gave me ~ 2300 rpm, and psi rise to 10. Second day at 4/day I ran the Polaris 280 with E-Z bag (psi went down some), and for past two days, a backwash and then 2 cycles per 24 hours. Filter pressure back down to 7 psi, went up to 8 overnight.
I think it may have hit the magic point some time during the night. The pool never has been totally sparkly at night and got worse and worse when I started using the Aquabot.
Comment on pump..... it is so quiet. And it is very sensitive to small amounts of organics and dead worms in pump basket. About 3-4 days in it wanted me to do a backwash, although the pressure hadn't risen much. With pump running there were bits and worms going up the basket about 3" but stuck to sides of basket and not filling the center. After I emptied the basket and removed the skimmer sock (changed several times a day because of fine "stuff" but little other debris becuase of the two Pool Skims and the Solar Breeze keeping most visibile debris up prior to reaching skimmer) it was happy again. :-D
I'll take more pics tonight with light on. I'm goint to post this and then get last nights pics uploaded to PhotoBucket and then will edit this post with pics.
Thanks, gg=alice
I'm not going to tell "FMTPG". He'll be disappointed that I didn't follow his instructions. Well not really, but I just wanted to say that. I might, though, get an "I told you so." :grrrr: 
No one has ever suggested doing this. This sure does make sense. 
I wish I had know this 23 years ago.
