The more I learn, the more confused I get! Please keep working with me as I DETERMINED to learn it all! - or at least some of it!
I know I'm jumping the gun a bit by taking readings now and not waiting until 24 hours after the asorbic acid and sequestriant treatment but I wanted to get an idea how much of what to have on hand.
Marie's instructions for the asorbic acid treatment say to use baking soda 24 hours later to raise alkalinity and PH - PER TEST RESULTS, of course. Somewhere I remember reading that the treatment will lower both. Yes, I know it's less than 12 hours later but here's what I got:
PH about the same as before 7.4-7.6 (after adding 3# of PH Down)
Alkalinity: 210!!!! I checked it twice thinking that I had screwed up
Neither was reduced by the asorbic acid, so far.
As an experiment, I tested the source water also.
PH: Below the scale on my test kit. It wasn't close to 6.8 which is as far down as it goes.
Alk: 30 to 40 - came up so fast I wasn't prepared
I'll take new readings in the AM which will be after the 24 hours.
In case you haven't guessed, I have more questions:
How do I lower the alkalinity? I have the jets pointed to ripple the surface.
Are the high PH and alk due to the cholorine, cya, and calcium hardness? If so, this is something that will be ongoing. If not, what are the possible causes? I also add to the water Heat$avr Liquid Blanket which is advertised to NOT effect the chemicals. Also, and maybe this is a biggie, I have a LOT of tree dirt falling into the pool. Leaves, etc. And we have just discovered that the gypsy moth problem that we thought was small is huge. I think a lot of the stuff I'm finding in the pool, on the concrete, driveway, etc
is gypsy moth catapellar dirt. Gross!!!!
