Hi Everyone,
I will start off by saying thank you to all here that have dedicated so much of their wisdom and time.
I have never had to post much within the forums as I really have not had any prior issues so , once again I’d just like to say thanks for any advice..
In Ontario, Canada and have a Vinyl 17000 gallon inground kidney.
New Vinyl Liner was installed five weeks ago.
The filling water is from a county filling station.
Filtration- Sta-Rite DE (S8D110) Grids New during liner replacement
SWG- Hayward T-15
Heated-Sta-Rite 333,000Btu
Pump-Sta-Rite VSF
After the new water was pumped in and running since , a build up of sand like grit could be felt on the bottom in the shallow end. I figured at first it was just dirt. After a couple of weeks with pump running 24/7 on low to medium speed, I started to notice a build up of white grit, flaky substance forming all around the bottom walls and floor within the deep end. I attempted to brush off but this was caked on and did not want to damage the new liner obviously.
Took samples to pool store while I was there picking up my own Taylor test kit.
the original readings :
FC-1.4
PH- 8.4
TA-250
CH-400
CYA-24
As of today I have added a total of 8 Littes of Muriatic Acid over a week time frame.
also have added liquid CYA (4L) jug
The white grit has started to turn into a powder as I can now brush it off the side walls and bottom but there still are a few stubborn spots.
My readings today still had a PH of 8.0 and TA -250
CYA-60
im guessing this is calcium but have not gotten that deep into testing.
What I am worried about is the amount of liquid acid I have had to dump in.
Any thoughts suggestions would be most appreciated!!!
thanks everyone
Ken
