yes... checking fc every hour right now

fc was 1 cc was around 2.5 mike

horse flies! Dang. so yesterday i was running around the pool with wasp spray shooting those flies. well after that i noticed that i had got some in the pool... kind of an oily patch here and there. i didn’t think much of it. so today i go to check the fc...1 ppm with high cc. slam here i come...

have you tried a robot?

how are you testing your water? can you post up your test results?

it’s funny how bad of advice a pool store “professional” can give. anyway, tim is right ... get a proper test kit first

i meant after the slam

i don’t think you’re running your swg long enough. a t3 produces about a half a pound of chlorine gas over 24 hours. in your 9k gal pool, that’s about 7ppm of chlorine per 24 hr day at 100%. that’s .3 fc/hour (at 100%). so your 9am to 5pm pump runtime would only give you a 2.7ppm increase in fc...

danny- did you ask your pool store how “perfectly fine” water can have algae ? i think that’s very telling.

take a 5 gallon bucket and time how long it takes to fill it. use that number and divide it out. then you’ll have a pretty good estimate on how long it will take mike

have you tried the diluted test?

i remember when a pool store told me my cya was around 150.... it was actually 300 you have to do i diluted test to nail down that number.... then you’ll know how much water to exchange mike

and buy the speedstir

please note that you can’t necessarily just drain a pool. bad things can happen. what kind of pool is this? what’s your water table level?

i remember when a pool store told me my cya was 150 when it was actually over 300. your in for some sort of water change

welcome to the forum... can you pick the sand up and get it between your fingers or does it just go poof and disappear ?

have you considered floating some pucks in there? maybe take cya to 50 and put a floater in. btw, i’ve had a few full sun days so far, air temp 85-90. when my cya was at 30ppm, i had an fc loss of 5-5.5ppm . i just raised the cya back to 50, but still loose 3.5 to 4

have you looked in your autocover box to see if there’s anything in there that might cause the smell

hi, at the start of this thread, you said your cya was 70...now it’s 45?

i had a similar event last august. we had a giant wind storm followed by heavy rain. my pristine pool looked like a farm pond in two hours because of all the dirt that the storm carried with it. your event likely carried a lot of pollen with it too. mine cleared up in about three days of...

to check your chlorine, use pool math an increase your fc to number that you like. then recheck it in 30 mins or so. if it tested at the level you expected, your fine. btw, my chlorine from july 2018 was almost completely dead

i’m in stillwater, so we’re close. last year i bought some from walmart, but most of it i found at atwood’s 4 gallons for $8.99 of 10%

i think he meant his fc is 18... i think he said his cya was 50

it’s important to slam at the correct fc/cya ratio. in addition, your fc needs to be checked very often, especially at first

if you raise your cya , it will take more bleach to slam

that will be a tough one to SLAM with a cya of 90, not to mention the cya level could be twice that number. i would get the recommended test kit a do a diluted cya test so you know. it’s possible that a water change is in order

is your fc really .5 ??
