Convert FROM Pristine Blue to chlorine

[johnmjankowski]

I inherited a 24 ft AG round pool that hase used Pristine Blue since it was installed in 2007.

What do I need to do to get started? I just got a new sand filter for the season to replace old filter with a hole in it.

Thanks in advance!

By far the easiest way is to drain and refill. I wouldn't recommend any other method, unless refilling will cost you over $200.

Too costly to refill the pool. Opened it up over weekend and have the following test numbers:
FC=0
TC=0
PH=6.0
Alk=30
Hard=70
CYA=0

What is first step in process? HELP

I don't know anything about Pristine Blue - sorry. But I can say that a pH of 6 will very likely be damaging to the pool. If this were a chlorine pool, I'd recommend raising the pH with Washing Soda (will also raise Alk) or Borax.

what is the copper level. Knowing that will give us info on how to proceed. If it is high it is very likely that the liner will get stained if you don't drain and refill at least partially. There are ways to help remove the copper but they are no inexpensive.

I got water tested other day:
Got the ecopper level tested last night! Here are the latest numbers:
FC= .31
TC= .31
PH= 7.1
Alk= 33
Hardness= 12
CYA=4
Copper = 1.0

I added a 32 oz bottle of Magic Jack Blue stuff to water last night.
Added 4 lbs of CYA to bring up!
What is my next step?

The easiest way would be to keep the chlorine & pH low for a month; run the filter 24/7 and use the CuLator package. Some of the copper should come out on the filter, and the CuLator will bind some. If you also use polyquat 2x per week during this period you will (a) reduce the risk of algae from low chlorine, and (b) improve filtration.

The CuLator product is a special patented plastic material, contained in a bag that goes into the skimmer, that can slowly take metals OUT of your pool water. We think it works, and have some evidence that it does, but not proof yet. (Not likely to be available locally.)
