Help with staining in attached SPA

[bxmartin]

Hi! Any thoughts on these stains in my attached spa. Opened the pool a few weeks ago and these were there. Still haven't gone away with brushing or stable chemicals. Thanks!!

You might try the following quick tests:
- Chlorine tablet held against the area for a short time - positive change would indicate organic residue at the waterline from sitting over the winter
- Regular vitamin C tablets (crushed in a sock or nylon) and also held against that area - indicative of iron in the water

Post back and let us know if either of those make a difference.

Ok so i did both tests! The chlorine tablet did nothing but a single vitamin c tab rubbed on the stain did remove it. So is my solution to just rub vitamin c over all the stains or is there a product i can buy that will remove it. Thanks!!

You can use more vitamin c tabs if you want, or purchase some ascorbic acid and spot treat those areas. Glad it worked for you. For future reference, you need to figure out where the iron came from - fill water or something metal left in the water or added to the water. On a well perhaps?

yes i am on a well, so i am guessing it is from that. After I remove the stains does it make sense to use a product like jacks magic stuff on a regular basis?

Absolutely! That should help contain the iron in the water and prevent it from staining as much if at all. Of course it will need to be replenished from time to time, but that's the nature of being on well water.
