I would appear as though I waited a bit long to test my water....
Ice is finally gone from the pool, been that way for a few days.
When I closed the pool, I bumped the FC up to 12, and I am assuming with the crud that fell through the mesh it got used up.
Hard to test water when it's got 6" of ice on it.....
Just tested, and 2 scoops of powder turned it just barely noticeable pink in 10mL sample. I think this means maybe .01 ppm??? It wouldn't have taken 1 drop to clear it.
I don't have the pump and plumbing hooked up yet, so having to circulate with an oar. Not the best situation.
I was going to ask about the powder, as it has turned a bit dark, but I see that question has been answered already in another thread.
I've added about 2 1/2 cups of bleach to the water, and circulated it a bit, probably not enough for a good test. Pool is about half full, so safe to assume 2000 - 2500 gallons.
Got most of the debris off the bottom. That will have to do for now, as I need to hard plumb the in wall skimmer, so can't fill the pool yet.
water is just a little cloudy, from the dirt I stirred up off the bottom. Temp is about 55*. That may be what is saving me from having a swamp.
