Pool water problems

[SWTREGO]

POOL FORUM , THANKS YOU FOR GETTING BACK TO ME , i PURCHASED A " INSTA - TEST KIT 6 PLUS" MADE BY LAMOTTE YESTERDAY AT A LOCAL POOL SUPPLY STORE , THE FOLLOWING ARE THE READINGS THAT I RECIEVED,

FCL ( FREE CHLORINE ) .5 PPM
TCL ( total chlorine ) 1.0 ppm
alk 0
ph 6.2
th 100
cya 0

according to thewse readings , I need to add soda for the low alkalinity , sodium bicarbonate for the low ph, calcium for the hardness, any cyuranic acid to stabilize the chlorine levels . The pool was very foamy this morning when I took the readings . I will get the chemicals today and see how things progress. The pool is a gunite pool , inverted kidney shape, approx 22,000 gal . The pump is a hayward " northstar " 1.5 hp , I also have a smart oxidizer SPP70 Commercial model , Hayward booster pump for the phantom cleaner , and a cartridge filter system . So far I have went thru 9 16 oz packets of the HTH
super "shock & swim" which is 52% calicum hypochlorite. I am on my 2nd round of 3" tablets in the chloronator. I checked it last night after testing the water , and they are almost dissolved . In the past ( 6 tablets would have lasted approx. 2-3 weeks ) The pool was opened 13 days ago . I have not added an algecide but did put in 7 oz of a clarifier 5 days ago, which did nothing . any input on the above would be appreciated , Thank you again for your input, SWTrego

You need to get your pH up as soon as possible. You can raise pH and alk at the same time by using washing soda, or by using Borax for the pH and baking soda for the alk. You also need to make sure you get adequate chlorine in the pool before you get algae. With no CYA that mqy mean adding chlorine multiple times daily. With a gunite pool, you also need to get your cacium levels up, so using cal-hypo to chlorinate would kill both birds with one stone.
