ok, sounds a little gross, but understand that i am on pure sand, and the water table is only 8.5' below the surface. i have a very active sump pit currently, and it appears crystal clear.

I purchased the tf-100 test kit recently. what tests should i run to see if this water is acceptable to fill my pool with?

thanks!

I would say everything except Chlorine & CYA. There shouldn't be any of those in there. The only thing I can think to be maybe concerned with would be fertilizer leaching if you're fertilizing heavily or maybe some other compounds others may think to be a worry. I would think it would be a pretty good source of fill water. Anyone else?

I would have it tested by your local health department to drinking water standards. That'll test for things that you can't test for. You can handle Bacteria and plant life but you can't handle some chems that may be in the water.

well...lesson learned.

i came home to find the pool guy had the liner in and was filling with my two hoses. i hooked up my sump pump, let it run for a few minutes and grabbed a glass and had a drink...(i know...not too swift). tasted fine to me and looked crystal clear, so i threw it in the pool and by my estimation, it probably filled 70% of the pool.

i could see a slight greenish tinge to the newly filled pool... so i pulled out my test kit and did some reading. obviously, FC was 0, so fearing i was looking at an algea bloom beginning, i added enough bleach to raise the FC to 6ppm. an hour later, the water looked like steeped tea. i could not see the floor of the shallow end.

i figured i was looking at the results of the clorine killing the algea...but doing some reading, it appears i more than likely have a high iron content. i filtered for half a day straight and cleaned the cartridges...they were very dirty but cleaned up reasonably well.

i did some more reading and realized, that the best thing would be a complete dump and refill with just the city water. unfortunately, unless i get the pool builder to put the vacuum pump back on, i cant completely drain the pool (he said no less than 4" in the shallow end). so i am currently pumping it out.

dang.
