I partly drainewd my pool a couple months ago to lower my CYA and I took some pictures at the stains. I'll have to post those, as the stain appears to be on parts of the plaster that hasn't worn away / degraded. So you may, in fact be correct. Huh, whattayaknow.

Hmm that's the first time I've heard of that; not that I'm doubting you - just sayin'. Anyway, that looks very similar to what I have (see first post)....

no never did. I ran the ascorbic acid treatment twice, but since is is warm out I battled algea - yellow and black - and it didn't seem to reduce the stain. So I just cleaned it up with lots of bleach and have beautiful water now, but still stain. I may run the Jack's magic treatment this...

Wow - momma told me not to ask about money, politics or religion. Prolly should add SWG in that...

Do the cells reduce flow / pressure? I am probably already too low for my Legend II.

Sounds like a summer-on-the-side money-maker to me....

thanks lovingHDTV - your info is interesting for a few reasons: 1. I am in Houston - similar season 2. I have several trees too. 3. I am putting in 1 182oz jug chlorine/day (like you were) 4. I have had mustard algae problems with pucks (I use them only now when we go away for the weekend) 5...

Well durn. We moved into our house and pool last summer. The old 1hp pump went out within a few months and we upgraded to a Pentair WhisperFlo 2-Speed 1hp. Well, now that we are running a Letro Legend II pressure-side pool cleaner it seems that we have barely enough pressure/volume for the...

hoo boy good read

Awsome - just what I am looking for - I am going to have to check out that calc "off-time"...

So, are there any numbers out there for: salt vs. bleach usage? electricity usage for the SWG? pros/cons? I am trying to understand what I will be in for ($) if we convert to a SWG as we swam in one at a hotel this weekend and oh my it was nice.

eww that's not sounding good. So, OK to shock after the ascorbic since a) it doesn't seem to be doing much, b) pH and alk are low (limiting re-deposit of any metal)?

Hmm I seem to recall that it was test 2 & 4 - I can't remember.... I do remember a metal stain ID tho.. Anyway, kids are out of school soon and they're anxious. Pool is cloudy and green at the edges (algae), so, cleaned the filter today - this is the second time it's been filled with green and...

Update: OK, 5 more lbs of ascorbic acid and 5x32oz of Metal Hold added and not much change after 24hrs on re-circ. pH was <6.8, Cl 0 and Al 40 beforehand. 3min of ascorbic in a sock against the stain did nothing, 30min began to lighten the stain, but not near what Jack's Stain ID kit did when...

OK makes sense - but put in puck even though stain is not completely removed? Maybe tell the kids the pool is closed until further notice? :twisted:
