Re: Brown water in pool- from Iron
Sorry I haven't answered sooner. I was in Texas, then flew to Philadelphia to attend my nephews graduation party, then today to my future daughter-in-law's bridal shower I am now homeIf it were my pool, this is what I would do:
Put a puck in the skimmer.
Start to add cya (stabilizer) - I am not sure how much you need for your salt system, but cya takes a while to register. I would put it in a sock and hang it by the skimmer. You don't want to put it in the skimmer because you will need to backwash often now, and you don't want to backwash any of the cya out. If you hang it by the skimmer, and squeeze the sock every now and then it will dissolve.
You have to continue to lower the alkalinity - just keep adding muriatic acid and keep the water aerating to raise the ph. Just make sure you don't let the ph to get too low - the puck in the skimmer will also lower ph. You can add borax if your ph goes too low. It will raise the ph without raising the alkalinity. (I know this is all confusing) The reason the pool store does not want you to add bleach right now is because the bleach will break down the metal out. So while I agree with this, a puck in the skimmer will add enough chlorine to keep the algae away while your cya is at 0. You can also add some polyquat 60 algaecide, but the algaecide also uses up chlorine. I know all of this is complicated, but once you get your water in balance it is very easy to maintain. You really have to get your alkalinity in check, because unbalanced alkalinity will cause a ph bounce and then it is hard to maintain a balanced pool. It all works together
I just read that Aylad answered your post - what she said It is the same advice.
