I installed a 1.5hp Pentair Whisperflow today I got off c-list for $220. He replaced impeller and seals. Anyway, I set the jumpers for low voltage to go with my 110v supply. Initially, it didn't want to turn but rather buzzed loudly. Drained the capacitor and tried again and it ran just fine...

22,000 gal in ground 70' of 1.5" pipe to pump from skimmer and drain Hayward super pump with a 1hp marathon motor and Hayward 1750 cartridge filter. My motor is dying and have come across a rebuilt 1.5 sta-rite dura-glas or 1.5hp Pentair whisper flow setup for $140 on c-list. I would like to...

I have a question about maintaining a Target FC level above that recommended per the CYA chart. Is this pointless and futile? Restated, am I wasting chlorine because there is not enough CYA to support and protect the excess? I like to have a buffer from my Min and Target FC levels. Currently my...

I like this little contraption but would like to have more adjustment flexibility both in terms of wait time between measurements and finite control of the flow valve. Is there a way to read the chlorine level from the return and calculate if that level is sufficient to cover a pool of X...

FC=5 CC=1 OCLT=2.5 pH=7.6 TA=70 CH=325 CYA=45 SALT=2000 BORATES=50 TEMP=90 The pool is crystal clear but with the current CC and OCLT, I am concerned something is lurking in the background and maybe I should take preemptive action. We have had a lot of rain the last week or so. So, SLAM or no...

My pool water is so perfectly amazing, the frogs lounge in it at night; sometimes leaving eggs. The sweeper takes care of the eggs so it's not a huge problem although my wife is petrified of frogs. Sent from my SAMSUNG-SGH-I747 using Tapatalk

Is there a magic set of number by which we can keep our eyes open under water without risk of irritation? I have seen the recommended chemistry levels and the CYA chart. I also read tears have a pH of 6.5-7.6 with average of 7.0. My plaster pool is running pH:7.5 but since my CYA is mid-range at...

16x32 (25k) plaster (30 days since resurface) TF-100 results: FC=7.5 CC=0 PH=7.8 TA=100 CH=375 CYA=50 Borate=50 Temp=85 CSI=0.37 I added 17 boxes of borates 3 days ago along with 5+ gallons of acid. Within the first 24hrs I was astonished by the clarity increase in the pool. Now, the clarity...

I am consistenly reading 450ppm CH with the TF-100 with 3 samples. Ran it to Leslies to get data logged for resurfacing warranty and they read 250ppm. I am new to the TF-100, but have been very religous about following directions and have read the expanded directions on the forum. Could I be...
