    Does Chlorine lose it potency in sealed containers?

    I believe 2 months is generally considered the 'shelf life' of sealed containers of bleach. It will have a date code on the bottle.

    Where's my CYA

    Pool is IG vinyl 18 x 36 with a deep end, a bit under 30,000 gallons. Filter is sand, 300lbs I believe. The pool is only 3 years old, been doing TFP since the beginning.

    Where's my CYA

    Pool is now holding CYA at about 20. From reading about CYA->ammonia, I suspect that was my issue initially. It seemed to use a lot of chlorine at first, but I assumed it was the algae. Pool is still blue-green though and doesn't seem to be clearing. Not a lot of FC use and I'm holding it at...

    Where's my CYA

    TA was 30, I've since added about 20lbs of baking soda but haven't re-tested. FC was 7 this morning (confirmed by pool store, FWIW), down from 10 last night. Pool is green from algae. It was mainly on the bottom after opening but I brushed everything to stir it up. I pump my pool down to...

    Where's my CYA

    Opened my pool yesterday morning and started testing. ph 7.2. CYA was 0, which I've not had before --usually there's at least some when I open in the spring. I added 5 lbs of dry stabilizer via skimmer sock. CYA should have at least been 20 , and my CYA test showed some cloudiness but was...

    Poolmath app suggestion: bleach date code converter

    On the bleach price screen, add functionality to convert a bleach date code (year + day of year) to a calendar date and show how long ago it was.

    How the heck do I connect a 2" backwash hose to a 2" pvc backwash hose???

    Re: How the heck do I connect a 2" backwash hose to a 2" pvc backwash hose??? I had to do this a few weeks ago. I used a heat gun (cheap one from harbor freight) to heat the end of the backwash hose, then my fingers (gloved) to stretch it. Repeat a few times. it doesn't take much heat to...

    Pool safety covers -- are they a China commodity now?

    New IGP, 18x36 CES. I'm researching mesh safety covers. Looking on Amazon and pool sites, I see a lot of the same product pictures, yet with different brand names and prices. The brand names seem to be specific to each seller -- I can't find the brands elsewhere with Google. Have safety...

    Backfill and Slurry Question

    Maybe build a retaining wall? Keep in mind, it may void your warranty. I would not put any plastic or barrier against the pool since it can trap moisture. Use drainage gravel to allow most of the water to drain away and any remaining moisture to evaporate.

    Backfill and Slurry Question

    Is your pool approved for partial burial? If so, the manufacturer should specify what's allowed so the warranty isn't voided. I doubt it's a slurry mix. I think it's typically non-compactable material like drainage stone.

    Newbie! Electrical Questions!

    I live in the Kansas City metro area, but in an unincorporated area. The county is currently using the 2011 NEC. I've talked with the building inspector a couple of times on the phone about swimming pool requirements. Things are somewhat "relaxed". That said, I'd prefer to go beyond the...
