Renamed thread to "What's the Problem with Well Water?"
------------------
And the answer is . . . well water often contains chemicals that greatly complicate pool care.
In various parts of the country, well water contains iron, manganese, silica or other metals that cause no end of problems with stains, clouding or deposits.
I've succeeded, many times, in OPERATING commercial pools with difficult water and for years, mistakenly thought I could help homeowners do the same thing. Unfortunately, as best I can make out, my batting average with helping homeowners via the Internet is 0.000! Managing difficult well water seems to be too complex, and to require too much consistency in treatment, for homeowners to manage it successfully. It's not impossible, in theory, but in practice it's proven too much for people.
Not all well water is difficult: limestone water (karst wells) can be very easy. Coastal sulfur water may not be a problem, but I have no experience and simply do not know.
If well water -- like yours -- is COMMON, than local pool stores MAY have a solution. Unfortunately, most pool store 'solutions' are 1/3 function and 2/3 useless (or worse) profit driven recommendations. So be careful. And keep in mind, if water LIKE YOURS is not common, then their advice is likely to be useless.
Managing well water summary:
- Requires ACCURATE knowledge of the problems: iron? manganese? sulfur? silica? magnesium? high calcium? acid?
- Requires (in almost all cases) a properly matched and well-functioning pump and filter system (which few above-ground pools have)
- Requires accurate day-to-day testing
- Requires a complex management plan that is 1/3 chemistry and 2/3 methodical, consistent pool care.
So what's the BEST solution?
- Get lucky, and have well water that happens to NOT be a problem, OR
- Get lucky, and stumble onto something that works for you. It happens in a minority of cases.
. . . sorry!
