If you have a chlorine pool and using either an in-line chlorinator or a floater your CYA level will increase.I have a new pool in costarica , i raised the CYA levels from 0 to 30 adding CYA ,only once at the beginning ,now after 5 months CYA level increased till 100 ...but i didn't put any more in the pool ...
HI,thank you for your reply,
OUTDOOR POOL APRIL 2019 COSTARICA 20.000 liters 5mt x 3mt x 1,20mt
CHEMICALS I USE :
CHLORINE: i use tricloro (tricloro-s-triazinetrone 99%) direct in the pool (at the store i could find only domestic liquid bleach at 3-4% so i didn't buy it )tricloro instead seems to be more effective here in the tropics with all the organic every day fall inside the pool ,am i wrong? does tricloro contain CYA?
CYA: added CYA only once in april to increase from 0 to 30-50 ,worked good for 5 months but even after all the rain we had , CYA is now at 100 ,how is that possible?
MURIATIC ACID /SODA: i used MURIATIC ACID for 2 months april,may, to low PH and got it stable at 7.4 ...(before was at 8 couse the water well) than raining season arrived (strong rain may and june-july) and PH low till 7.1 like 2 weeks ago ,so i added for the first time SODA and get it back at 7.4 but seems to get lower every day.
i don't know i have to read the instruction on the bucket at the store , but is the common household bleach to clean .....they all are at 3% but i find one at 3.5% ....so if i double the dose i can reach 7% and put it in my poolHow many gallons is your pool?
Is the bleach pure with no additives, fragrances, polymers, anti-foam chemicals, etc?
till november a lot of rain than from dic till may dry ,fill water is expensive,Do you get a lot of rain? Is your fill water relatively cheap?
Calcium Hypochlorite may be more available. As long as you do not have calcium issues.
about 5.000 gallons or 19.000 liters in the pooli don't know i have to read the instruction on the bucket at the store , but is the common household bleach to clean .....they all are at 3% but i find one at 3.5% ....so if i double the dose i can reach 7% and put it in my pool
i think at the lower level around 30 is the best what do you think?Your pool will use around 1/2 gallon of 3.5% chlorine a day.
What CYA level are you going to keep your pool at?
i bought taylor k2006 but i didn't get it yet ,so i borrow k2005 from a friend
