Should I replace water? stains back after AA

[LooNTooNs]

So I did a very successful AA treatment about a month ago. after about two weeks and the FC coming up, the staining is back and looking even worse. It seems that the staining in more concentrated, where some areas are still clear, the stains look twice as bad in other spots.

So heres the question. am I better off doing another AA treatment and then replacing most of the water? I am trying to figure out if the cost of replacing the water will be cheaper and less hassle than a whole summer of sequestering. I have already dumped about $400 in AA and sequesterant.


Any thoughts?

Does your new fill water have iron in it?

I hear ya! I myself had the same issues and I tested my tap water and it was clear of metals. I removed half of the water out of my fiberglass pool. I could only do half because my floor started to get spongy. Two days post this process and the pool has recovered. I am going to hold my ph at 7. I have my FC at 1. I have added the CUlater product. My long term goal is to not have to deal with adding sequestrate. Good luck I know how frustrating this can be.

I had my tap water tested an there is very low level of metals. I have ordered another 10lbs of AA. I plan on treating this weekend.

I am curious how much water I can remove safely in the pool. Is is a steel wall vinyl pool. My local store told me that it is not safe to drain the water. Is this true?

It is safe to drain almost any pool in 1/3 increments. It is not always safe to drain a vinyl liner pool but sometimes unavoidable.

What do you mean in 1/3 increments?

 

[chem geek]

1/3rd of the pool's water volume.
