Chem Geek or Mbar - are you there? Iron test question.

[mbar]

My advice is to look at your pool - if it looks good, don't worry about it After many years of trying to find out where the metals were coming from, and how to get them out of my water, I came to the conclusion that I would deal with the stains as they come. I hate stains, and I am not a chemist like chemgeek. I just give the benefit of my experience. Now I just enjoy my pool and deal with the dreaded stains if and when they come

You're right mbar! Thank you so much for sharing your wisdom with me! It's greatly appreciated.

Right now, I have the pool at shock level to rid a high CC (and I seem to be winning). I have liner stains as well, and they're driving me crazy - because from a distance, it makes my pool look green (liner is blue and white with an alligator-skin pattern) and I feel like I worked too long and hard to get the pool in shape to be left with it looking any less than perfect. ;oP

Should I hold off on an ascorbic acid treatment after just fighting off a potential bloom and wait for the pool to be stable for a little bit?

[mbar]

Yes hold off. I would get the chlorine to hold steady overnight. Keep the ph low at about 7.2 - when you are finished shocking and the chlorine is holding, then add more sequestering agent. This should take care of the staining. If it does not - then just add a small amount of ascorbic - just a cup or so around the sides of the pool, and put the pool on circulate for a couple of hours. This should do it, you should not have to do a full treatment. The small amount of ascorbic should work without having to rebalance the whole pool again. It will take down the ph so just make sure it does not go under 7.0. When you get to this point it is just a matter of tweaking the water to get the right amount of sequestering agent to keep the stains away.

Will do mbar!!! Thank you so much! I've come a long way since I took that cover off - and I certainly couldn't have done it without the great people on Pool Forum. I've already learned so much (but what I don't know still could fill a warehouse, I'm sure!).

I am not a chemist like chemgeek.

Just for the record...I'm not a chemist either, don't have a PhD in chemistry, don't work in the industry, etc. I did major in physics & chemistry at Cal Berkeley (field major in physical sciences since they didn't allow a double major in those two due to too many overlapping courses, mostly in math). I rekindled my interest in chemistry when I got my pool 7 years ago and ran into problems when using Trichlor tab/pucks. Did some chemical research and found The PoolForum.

I totally agree with Marie that if the water is clear and there is no staining, then don't worry about the varying metal measurements -- at least one of them is wrong. The 5 ppm sounds suspiciously high, even if sequestered.

That's a lot of math, Chem Geek!

We do have staining - but we had a brown pool over the course of several days - on 2 separate occasions.

5 was the highest reading we'd gotten. Right after we filled and it turned brown, it was only a 3. It couldn't have gone up 1.5 times when significant amounts of new water hadn't been introduced. So, I agree with you CG - it is suspicious. Not to mention the fact that the boy who did the test looked all of 12.

I no longer have the desire to know what the iron level is. I think I was just caught up in it because we fought it for several weeks. Truth is - it's not interfering with anything right now, so who cares. If water turns, I'll filter it out again. Done. Moving on.

Thanks for putting up with my neuroses!

Sounds like you have a good handle on your pool at this point. Time to move on and just enjoy it now. Don't fret over every little speck or your pool will end up being all work and no play. Glad Pool Forum was able to help you. Now time for you to go have fun! Good luck.

[labdi01]

Thanks Watermom.

The forum has been vital to our success. I'm sure I'll have other things crop up - but for now - we're almost there!

You may not be a chemist, but I would trust you in any chemistry questions that come along Chem Geek

Hey my picture turned up!

Marie,
What do you mean your picture turned up? If you are talking about your avatar, I've been seeing it for days.
