i get that and hate all of the misleading names and descriptions. i guess the real question I'm asking is there a real difference other than the percentage? the cost is well over double so unless the "shock" bags dissolve or have something else in them i can't justify the expense. am i being...

Recently my girlfriend had purchased a 50 lb bucket of cal-hypo at 68%. for $135.00. She also purchased a box of shock (same Brand name) cal hypo 78 % of 12, 1 lb. bags. (12 lbs.) for roughly $60.00. Am i incorrect in thinking the "shock" is way overpriced or is there something i am missing...

i am a new member and just had the same exact problem which led to me draining my pool. if you are using tricolor or dichlor to sanitize it is probably the cya like LFrankow says. my pool store told me i could go well over 100 with cya before worrying and that is simply a lie. my pool was...

thanx again, I would never mix chemicals, its just printed on the chlorinator itself so I just wondered why no cal hypo if I started with it? they make 3" pucks too right or are they not slow dissolving for chlorinators? I intend on taking your advice and using bleach as much as possible but...

what is shock level free chlorine? i am confused about the pool math or pool calculators. they are telling me i only need a 1lb. 16 oz bag of dichlor to get from 0 free to 4 ppm. i did that and of course it isn't enough. how would 1 bag be enough chlorine when i have zero? my test read...

my new water which is basically tap water now is reading 0 free cl, 2 total cl, 7.6 ph, 70 alk, 100 CH and 0 CYA. i was going to use hypo cal pucks since the chlorine and ch are low but hate the idea of all that inert stuff going into the water. from what I'm reading i should use just...

thanx i just refilled my entire pool unfortunately i exchanged 18,000 gallons. i only had a little water left in the bottom so I'm guessing my pool is a 18k pool now. i am considering swg but i read that some stainless filters and some older heaters aren't compatible with salt. i have both any...

just adjusted my sig i guess it was too many lines.

i did that but i don't see my signature on my threads

I'm going to drain the pool tonite and refill it wednesday morning. i am going to drain it down ta almost nothing and start from scratch. i see its recommended to have some cya in the pool. should i obtain that by using the trichlor again when i chlorinate? i have a new unopened 40 lb bucket of...

Thanx, i kinds thought that was the only thing i can do. even if i change to a SWG the cya is still going to demand a lot of chlorine correct. it may not cost so much but the chlorine would still be very high in the pool messing with skin and hair i assume?

i am new. thanx for any help. i ran out of reagent for cya and my reading went from 70 on 6/16/2017 to 160 ish today. my test goes up to 100. first test was over 100 so diluted reagent to half then doubled the 80 reading i had. guessing I'm around 160? my history upon opening the pool was...

First thread, I decided to look for help from some good people who have some of the same issues i am experiencing. I am a newbie but have a pretty good "basic" knowledge of pools and chemicals but get a little confused sometimes on which way to go or options to take. I am sick of being...
