SLAM and possible broken lateral - HELP!

[Geojaneo]

Day 3 of Slam process. Current reading

FC 16.5 ( goal 20)
CC 0
CYA. 50
TA. 70
PH. 7.2

Failed AA treatment and could not hold chlorine to minimum so began SLAM 7/28. Slight amounts of sand in pool. Filter backwashed and so nasty cleaned sand. It’s 10 years old so will replace. Assume broken lateral(s) so ordering new ones.

Can this problem affect SLAM? Water has remained clear entire process but losing 4 ppm overnight. Few days to receive and replace laterals. Continue to SLAM? Used 12 gals of bleach so far. Please help!

have Fiber clear - should I add? What about using SWG to aid at this point?

Why are you assuming the laterals are broken? Have you checked the gasket on the multiport valve? Are you sure its sand and not dead algae? Also sand doesn't need replacing unless it is calcified. Sand can be deep cleaned and reused. deep clean sand filter

When cleaning filter sand found black plastic piece less than 1/4 inch. Tried DE recently and pressure would not rise as it did last year. I’ll get in pool and check the debris more carefully. So continue SLAM at this point without SWG ???? Thanks for quick reply!

You can continue to slam. Keep the SWG off and put the filter on recirculate until you figure out if there are broken laterals.

Day three of SLAM - thought it was sand but it feels like "scum/grease". Is this algae - never seen this color, but finding in skimmer baskets past several days. Also on pool floor and on steps! Smells awful, fyi!



Did a deep clean on filter day b4 yesterday. Still losing about 4 ppm each reading. Posted earlier in this forum and wasn't sure if I needed new post or add to original one - test results posted in other thread.

Thanks for any help!

Good luck. I’m struggling with similar issues.

You too! Have to drive 45 miles to get more chlorine, but at least getting a nice steak dinner out of it! What's a "bubbler"? I grew up in Rhode Island and that is what we called water fountains that you drink out of!

That looks like the stuff I have been battling before I started nuking it. I wish my chlorine runs resulted in a steak dinner

Good Luck!

Have you gotten rid of the stuff that was appearing on the steps and on the floor?

That stuff is how my mustard algae looked on my skimmers and steps, but on the floor it looked like light brown to sandy patches, spots and streaks. And...when I would prep my vac hose for vacuuming, that sandy stuff would come out. That stopped once I kept the hose submerged while treating the pool. But, my battle was a long one

I hope yours is over
