Update. 16th day of SLAM. Daytime chlorine loss was high, so I checked CYA and it was down to 0! Surprised me, as I thought there was no way to reduce CYA except by emptying an amount of pool water. I added 32 oz CYA in a stocking in the skimmer, after it dissolved, I added 32 oz more. Not sure...

As far as I know, nothing else in the water. Re-plastering finished in May with a fresh fill of hose water. Pool remodeler added only calcium shock and CYA, and it's been fine since then. Using TF-100 test kit for testing. @BasicTek, sun has been normal for around here... lots of it, not much...

A few weeks after my chlorine dropped to 0 while on vacation. I noticed a few algae spots in my newly refinished pebble tech pool, and I scrubbed them with a chlorine tab, but they didn't go away. I decided it's time to SLAM. I've been SLAMming for 12 days now! CYA was at 55 when I started...

@JohnT: That's something I hadn't thought about. Good idea. @Bama Rambler: That's what I thought. I'll give it a try since I don't have to go out and look for a clamp to implement JohnT's idea. Thanks!

I've purchased the Liquidator with the 3/8" upgrade kit (thanks to the guys at http://www.poolservicestech.com) and during installation, I had a problem with where I should put the "out" line from the liquidator. Instructions say to put it before the pump strainer basket, but my valve to select...

I did the same thing. "What harm could there be?" I thought... I wound up using an enzyme based additive, and then just going around the pool with paper towels and wiping the tiles down. I wound up using the additive several times more, but only a few ounces at a time. Looks good now...

Good thought. I do have a light that could have algae behind it, and of course, I'll double check the pump baskets, etc. To check the filter, do you think I need to do a teardown and thorough cleaning of the DE grids, or is a backwash sufficient? Thanks!

So to be sure I have absolutely no organics, do you recommend shocking? I did shock it about a month ago because the pool guy never kept the FC high enough to compensate for the high CYA. I thought I had done a good shock, but near the end I ran out of titrants, and couldn't verify my levels...

I've gotten my pool balanced after firing my pool guy. I have a question about how much chlorine usage/loss is normal for a pool similar to mine. When I read the threads, it seems like mine is using considerably higher amounts. After dumping the pool guy, I drained the pool to get the CYA...

@meatloaf- How much bleach / week or day do you wind up using in your pool in the summer to maintain FC?

Thanks! I'll give it a go at this level for a while and see how it performs...

Bought a house with a pool, and had no knowledge of pool care, so I opted to have a pool guy come and do just the chemicals. He never got it right last summer and I was back and forth to Leslie's, dumping all sorts of crud in there, which sorta worked! I did chems myself during the 'off season'...
