Discolored drains and return spouts

[aday31]

We have a saltwater pool that’s just a year and a half old. The drains and some of the returns have discolored to a yellowish color. Does anyone know why this happened?

Probably metals like iron.

It also looks like maybe copper and silver stains.

Can you show the system?

Do you have a mineral system?

Can you pull the cartridge and show it before and after cleaning?

Hi-

Thank you for your quick reply.

We have a DE System.

We have two bowl fountains that have a cooper lining in the spout where the water falls over into the pool.

Any thoughts on what to do?

Thank you.

We also have a Hayward heater.

All saltwater systems. Do these help?

Thanks

I don’t know why the photos keep saying too large for the site to upload.

Where is the salt cell?

Can you remove the cell and show looking into the cell from both ends and looking into the pipe where the cell commencts?

Can you pull the grids and show them before and after cleaning?

Can you post all chemistry readings and all chemicals that have been added?

I don’t know how to do that.

Attached is snap shot of the chemistry numbers.

Cyanuric acid level?

Can you post a list of all chemicals that have been added?

I don’t have the acid level. Can a pool store measure that if I bring in a water sample?

Just salt- when needed.

They can, but it is not reliable.

We recommend your own testing with a good test kit.

Thank for the test kit suggestion. I will get that.

Any suggestion to tear the metals in the water - if that’s the issue? I’m concerned with added treatments as the pool is on the new side and we have a gas heater too. I don’t know if that complicates things?
