Black Stains On My Above Ground Saltwater Pool
by Randy
(New Jersey)
I changed to saltwater in my above ground pool.
It has black stains on the liner from the winter freeze.
How do I get that off of the liner without hurting the saltwater?
Is there a special cleaner to use for saltwater?
Thanks for the question Randy
First you need to verify what the stains are.
This is a good post for stains on a liner:
Vinyl Liner Has Dark Stains On Bottom
This post basically tells you how to identify which stains they are, either mineral or organic, and what to do for each case.
Salt water pools are basically the same as chlorine pools. There are a couple of exceptions, but they're pretty simple and straight forward.
I would encourage you to look over these pages:
Salt Water Swimming Pools
Chlorine Generator
How Do You Clean A Salt Water Cell?

There's lots of great information on the Q&A page concerning salt pools and chlorine generators:
Swimming Pool Questions and Answers
I've been the pool operator for our YMCA salt pool (80,000 gallons) for the last 3 years and the above posts are what I've learned since then.
The main thing is to test your salt level and keep it within range of what the manufacturer sets. You'll want to get a hand held salinity meter.
The one I use is an analog Myron salinity meter.
Don't simply push a button on your salt cell. The salinity needs to compared to a manual test.
This is why many salt cells have burned up.
You remove stains in a salt pool as you would any regular chlorine pool.
Hope this helps and have a fun and safe Summer.
