pool opening / iron stain after winter

[te-chi]

hi … newbie to TFP
i am dealing with the infamous iron stain (kind of gold colored) on the gel-coat of my inground pool….. spring coming should i treat the stain first (with AA treatment with algeacide first or do the usual shock treatment and wait till chlorine gets low and then do the AA treatment? thanks in advance

Welcome to TFP.

Does your pool pass the Overnight Chlorine Loss Test?

To ajw22 … thanks for answering. No OCLT…. the pool isn’t started yet…. dropped water level, removed leaves and debris and realised that the iron stain came back…. water here is on the good quality side, (no rust stain in toilet and no scale around faucet)…. i know the AA treatment work (did it last year) but to start the season should i do the regular shock treatment or get rid of the stain and then do the shock….?

What is "regular shock treatment"?

Do you intend to drain the pool after the AA treatment to get iron free water in the pool?

Any opening pool kit ….no i may lower the level again but since it is a small (8x10) inground pool i can not empty the pool completely…i will have to had some sequestrant

If you are not dumping the water then follow the SLAM Process first then Ascorbic Acid Treatment - Further Reading

We don't recommend using pool opening kits and their chemicals.
