Hi awesome community!

First off, thank you for the wonderful resource and feedback. I followed the dichlor/bleach method after my last fill. The water is looking, and testing great!

However, often I can feel a very thin grainy film on the seat. The film isn’t visible but you can feel it. It dissipates quickly into the water and is easily rubbed off.

All users shower ahead of time. Also, I'll notice it even when there is not funk at the waterline.

I thought it could be due to CH with pH. However my tests are all normal.

Any ideas what it is and/or how to avoid it?

Any advice is greatly appreciated. Thank you all.Screenshot_20220131-070106.jpg
 
Sounds to me like dirt in the water settling when the spa is idle.
