Hi there everyone! I'm on my 6th day of the SLAM process -(Technically my 15th day , but my first 7 days were wasted because I thought my shock level was supposed to be 16 ug) - but I seem to be getting nowhere. 16.5K pebble pool Bleach for regular chlorination and shocking Cartridge...

Thanks for the replies and help! The app is called "PoolCalc." I've had it for quite a while. Maybe time to get the PoolMath app. ;) Keepin FC at 20 now for the SLAM. Finger's crossed. 🤞

Oh NO!!! ! I was going by the recommended numbers in the Pool Calc App. Didn't think they would be incorrect. Guess the app needs an update. Thanks for the info. I'll bump up the FC.

Hi there! I'm currently shocking my pool (16,500 gal/ pebble). CYA is at 50. I've been maintaining shock level at 16ppm, but I'm literally on my 7th day and still losing about 2ppm each night. Filter running continuously - except for about 1/2 hour yesterday so I could clean out the filter...

Hi everyone, I have an old (Prob 35+ years) Purex 36 sq ft. DE canister (aluminum) filter for my 16,000 gal pool. It's recently sprung a slow drip leak out of the bottom (can't pinpoint exactly where it's coming from). It only leaks when the pump is on, so I'm guessing there's a very small crack...

Thanks Richard!

OK,,, thanks for the info and the quick replies!! I'll will keep at it, and hopefully things will start changing soon. Fingers crossed. :testkit: Kind regards, John

Hi there, I'm currently Slamming my pool (16,500 gal, pebble tech). Algae unfortunately got out of control while I was on vacation. Had high CYA as well, so needed to drain partially and re-fill. I'm just about 24 hours into the slam process. There is some improvement in the color, but the...

OK, great! Understood, and makes sense. Thanks for the replies! It is much appreciated - especially on a Saturday. Kind regards, John.

Hi there! Haven't had a problem for years with my pool, (follow troublefreepool program) however I guess I slipped and I have a slight bloom of green algae on the steps. Beginning shock treatment today. Just curious to know if it's absolutely essential to run the filter *continuously* during...
