Iron in water source

[stcohen]

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

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?

I saw PoolDoc's post. Good looking family. I'm sorry for his loss, losing a parent is never easy.
Pool water is clear with a greenish tint. Still a significant amount of "rust" colored sediment on bottom.

F/U
Had to correct pH again this morning. Sediment seems to go back into solution with lowering the pH and water now green.
Adequate HEPD?

Hey. I am not an expert here (for sure!). I have been a pool owner/operator for many years so there are some things I know pretty well. However, I am new to the BBB method so there are tons of things I don't know very well. BUT I want to keep a conversation going in the hopes of attracting a moderator/expert, so let's keep talking.

Are you continuing with the cal-hypo/backwashing and the 1 cup Polyquat every other day too?

-HEDP is yucky stuff and it stays in the water for a while. I would hesitate to add more only because the purpose behind using it IS to get metals in solution and it sounds like that is what's happening.

You can use cal hypo tabs... 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.

As I understand it, the iron must be in solution for this to work. I used this same process with my iron-loaded new fill water and I am now metal-free!

I might suggest also that you go into "settings" and create a signature with your pool info. It helps the mods so they don't have to scroll back to see your pool specs.
