Newbie - Stain removal via ascorbic acid

[PoolDoc]

Keep your chlorine up, above 0.5 and below 2.0. Go ahead and lower the pH another notch.

Don't backwash too much. Brush if you like, but unless you think you're getting algae (slick sides to the pool) I don't know that I'd bother yet, until you can see what you are doing. 1x per day should be fine.

This morning readings were the same.
CL = 1
pH = 7.0

Added another qt. of muriatic acid this morning. Water is still cloudy/milky, same as last night,,will take sampe to pool store for a more complete reading.

Unless you have reasons to think your test results are wrong, I wouldn't go to the store. They are just going to have you 'fix' stuff we've been working to get right. Your stabilizer wouldn't have changed much; your alkalinity is down some; your calcium wouldn't have changed much more than the stabilizer (both due to backwashing & replacing).

So unless you need something from them, I'd stay away!

Keep filtering (and not backwashing until the pressure goes up); keep not adding stuff unnecessarily; hold your pH just under 7.0; keep a little chlorine in; use the polyquat weekly or 2x weekly.

And . . . . be patient. Pool owner IMpatience is the #1 profit maker for sellers of unneeded pool chemicals: they can't fix you up faster, but they can sell you something that claims to do that! They don't have magic wands for pools; they just pretend they do.

Amen to that!

No I hear both you on that,,I'm not about to go back and start buying their 'snake oil'. I wanted take it there as a cross check to make use my little test kit is accurate. (there's a standing order in our home, "do not buy anything")

Now that were starting to make some progress,(the stain is fading to almost unnoticeable) (just still hard to tell fully with the water being so milky) We now have some renewed confidence so it's much easier to be patient .

Thanks for all the help...I'll keep posting as we progress.

Hang in there--the results will be worth it!!

Current conditions as noon today: We can now start to see thru the water, shallow area is pretty clear and I can see my Polaris down in the deep end (not clear but can tell what it is). The stains are lifting and I'd say about 90% gone. Residual markings remain around the worst areas, but the ring around the top is pretty much gone and the walls look pretty good. Keep in mind about 50% of these stains lifted after my initial 5lbs. ascorbic acid treatment.

My current readings are:
CYA: 70
Tot. CL : 1
Free CL: 0
pH: 7.4
Tot Alk: 145
Tot. Adj. Alk: 124
Tot. Hardness 250

Having a hard time keeping the pH down. I added another 2qt. of muriatic acid after receiving the test results. I'm keeping two full trichlor tabs in the skimmer to ad in the CL. No backwashing (pressure has gone up about 4-5 lbs)

But were making progress !
