Iron in water source

[PoolDoc]

CuLator units work . . . very slowly and ONLY on dissolved iron. If it's orange, or in a stain, the CuLator has no effect.

Use the methods above, but order these:
CCH Calcium Hypochlorite Tablets 50 lb bucket

You can use cal hypo tabs like these in the skimmer -- ONLY in the skimmer -- to remove iron and place it on the calcium residue from the cal hypo, which is then trapped by the filter.

Chemically, what's happening when you use these correctly is pretty complicated, but practically speaking, it's very, very simple. Let me know when you have them, and I'll walk you through it.

OK, got the chems
6 quarts polyquat
1 quart Jacks Magic Pink
50 lbs Ca hypochlorite

pH 7.2
FC 0
Water deep green, almost clear with Fe sediment on bottom. Vacuumed to waste what I could. No stains apparent.

Waiting for instructions. Thanks

[PoolDoc]

OK, great.

1. Add a label dose of Pink Stuff -- I don't know what the label says, but just follow the label

2. Add 1 quart of polyquat. Then follow that with 1/4 quart every 2 days.

3. Make SURE there is no trichlor or any feeder in the skimmer or in the piping between the skimmer and the filter.

4. Make sure the pump is on 24/7. (Low speed is OK, if you have it.)

5. Clean the skimmer basket, then add 1 - 2 cal hypo tabs in to the skimmer.

6. Report how long it takes to dissolve the tabs. Don't add more than 1/2 pound per day.

It took 2 hours for 2 hypo tabs to disappear (1 tab in each of the 2 skimmer baskets).
Approx. how many tabs in 1/2 lb. for daily use?

Did you weigh them maybe? Weigh a bunch that you can measure on your scale and do some division. (Really just poking your thread because it might have gotten missed). You're doing great following instructions @pooldoc

[stcohen]

lol. Saw that as soon as I hit the send button.
Something slowly happening.
pH went to almost 8, lowered back to 7.2 with muriatic acid
Backwashed filter twice since started this. Discharging milky water, clears with in 2 minutes
Will stick with PoolDoc's regimen

Good for you! BTW, PoolDoc's Dad passed yesterday so you might not hear from him directly for a while. Let us know if you need help! Sounds like you are on the right track although I am a bit surprised that your backwash discharge is just white. White from Calcium but I think it would have an orange-ish tint from the iron. What color is your water now?

PoolDoc:
This is my second year of having to do the ascorbic acid treatment. Works like a charm. I stayed stain free until late August last year--Im sure its my well water doing me in.

My question is-can I use the calcium hypochlorite tabs with my DE filter? I'd like to try and get the iron out of the water. I do use the Culator pack in the skimmer.

Thanks for your time.

Hey! Your question is very specialized and belongs in it's own thread.

Unfortunately, PoolDoc is the Guru on this issue and is away from the forum right now.

I suggest that you start a new thread. Click "Post New Thread" here: http://www.poolforum.com/pf2/forumdi...erals-amp-Ions
