Hi Guys,
Ok I was called to come by to see brown blotches which only appear at dawn and dusk.
I've been servicing this pool for around 1 1/2 year and the chems are kept in check. This is Tuesdays report:
============ T E S T R E S U L T S ==============
Pool Equipment = Good working condition.
C.S.I. = -0.06 (Balanced)
Free Chlorine = 4
Chloramines = 0
pH = 7.8
Total Alkalinity = 70
Calcium Hardness = 300
Stabilizer = 60
Salt = 2900
Temp = 86F
Generator Output = 35%
Filter PSI = 20
============================================
The pool is about 22,000 gallons. It was built in 2007. Please click here for pic: http://a6.sphotos.ak.fbcdn.net/hphotos- ... 1218_n.jpg
In the sunlight you do not see hardly any discoloration but when the sun goes in you see it. Today at dusk the discoloration looked much worst.
I know why there is this discoloration. All the contractors on the island mix the Diamond Brite with unclean city water. I have read they highly recommend using clean water to mix otherwise discoloration can happen. All the pools I have seen on the island have discoloration. No one seems to know how to mix Diamond Brite.
My question is:
Does this discoloration get worst over the years and can a good thorough acid washing with pressure cleaner remove these brown blotches? Or at least make it look better?
Thanks.
