It's been a while since I've posted. I have some brown stains in my pool that will rub off with my hand but not with VIGOROUS scrubbing with nylon brush. Stains are also completely eliminated with vitamin c tablet. Passed 3 OCLT tests and pool is clear. Any ideas? Would a (light) iron stain rub off with your hand?

Do you use well water in your pool? What are your most current set of test results? It seems odd it would rub off with your hand but not brush off. You could try adding some sequestrant and see if the stains lift.

Thanks for the quick reply. I have city water but I dont use a softener. Would algae stains rub off with your hand and not a brush? I use only nylon not steel, if that makes a difference. This was as of last night:
Fc 5.8
Cya 80
Salt 3400
Ph 7.5

I have city water too...and a little bit of iron in it.
Not a huge problem, just a minor annoyance.

You could look into trying Jack's Magic pink stuff to lift the stains.
