Do you have any ideas how I could test what it is?

Do you think it's safe to use the spa? I don't think I can get Ahh-Some here, but I did use JetClean once in the summer and once last December. Maybe I should try a different product the next time I change the water :/

It's been several weeks since I changed the water and filters. The orange stuff came back a few times and I kept wiping it off, then it just disappeared and hasn't come back since! :) Unfortunately, the foam (or whatever it is) has gradually reappeared. Basicly, the water looks crystal clear...
