Thanks for the quick replies! I just added CYA to the sock, aiming for 40 ppm. I'll check it in about a week, and see how it goes, then bump up to 50 if I'm still losing too much FC. 22,500 gal, IG plaster Pentair FNS Plus 36, DE filter 3/4 HP WhisperFlo pump BBB believer, trying to be...

Looking for advice on CYA level... CYA 30 pH 7.5 TA 130 CH 260 CC < 0.5 OCLT 1 ppm I seem to be using a lot of bleach, FC to about 6 after dark, and by 3 or 4 pm next day FC is about 1 (Min should be 2 with my current CYA). Adding 5 ppm is nearly a gallon (112 oz) of 12.5%, which costs me...

By all means, go ahead and splurge on one. It makes doing the walls a pleasure. The downside is it's clumsy on the steps and tight areas, and it does put more strain on the plastic V-clip and holes on the pole. I picked up a cotter-pin type thingy for about $2.50 at the hardware store to...

Also, for those in the midst of the process, don't give up! I think I had to clean the filters (either backwash or pull and hose down) about 15-20 times through the process. Up until the last 2-3 changes, the DE would clog with dead algae and the pump pressure would climb to 28 PSI (start at 8...

Update: 12 days after starting the SLAM, and losing a day and a half in the middle (broken part on filter housing, couldn't run filter), I could finally see and retrieve the wayward Wall Whale from the deep end, vacuum out the last bits of debris. Today: FC 9 CC < .5 CYA 30 CH 260 TA 130...

Great minds think alike! That's the brush that's currently residing in my swamp. My problem is the holes in the pole are bent (actually ripped on one of my two poles) and the tabs don't hold tight. I got some "gorilla" heavy duty 4-pin V clips (made for the Gorilla line of pool telepoles)...

Yes, I raked and raked blind, not pulling out any leaves any more. Also have the APS (pressure type) running, its bag is coming up empty at this point. Had to remove the screen from the APS hose, as it keeps clogging with algae and no pressure was getting to the sweeper. Unfortunately my...

There's a speed limit? :-) 25,000 gal, IG plaster Pentair FNS Plus 36, DE filter 3/4 HP WhisperFlo pump BBB believer, trying to be disciplined enough to make it work!

Thanks guys! I'm happy to stay the course, just needed some reassurance especially that the no filtering (at first) wasn't detrimental to my SLAM. With further reading I've also figured out that keeping FC at or above shock is key... and when it drops even a few ppm below, the process just...

FC 13 at 8 pm. FC 10 at 3:30 am, CC 0.5-1 (nearly clear with 1 drop, definitely clear with 2) Added 12.5% up to 14 ppm. CC has been about the same, 0.5, through the SLAM so far. Add'l info: first few cycles my FC dropped 3 ppm every 30 min. Busy life, I had a hard time keeping the FC truly at...

Looking for help/advice. Heavy green algae burden, trying to reclaim the pool now. I did BBB last season, successfully, but lazily let it get out of hand this spring. It's swamp green. Starting: pH 7.2 TA 110 CH 220 Borate 30 CYA zero (!) - this surprised me as it was around 40 all last...

Aha! Learn something new every day. My pool has 4 eyeballs (I almost said "I have 4 eyeballs), and they are each 3/4 inch diameter at the opening.

The filter has a 2" slide valve on the side ports (to redirect flow for backwash). I'm not certain what you mean by the "eyeballs." Do you mean the check valves? There are check-valves on each of the returns that have clear covers... these are, again, 2" in and out, straight (the product...

2" pipes. Pentair FNS Plus DE filter, 36 sq. ft. Pressure is currently 12 psi (8 psi when freshly coated with DE). If it makes any difference the "Service Factor" on the 3/4 HP WhisperFlo is 1.67.

Thank you!
