Welcome to our forum.
Got it empty and most of the crap collected so I rinsed it well until we got to about 30% full, ran the pumps a bit to clear the lines, drained again, cleaned up what was left in the bottom of the tub, rinse again, ran the pump, drained and then filled it back up.

I am curious if there is any concern of damage by running the pumps without all the jets submerged? I thought I read in the manual to make sure all the jets are under water before running the pumps, but with only 30% of the tub filled most jets would be above that level.
What determines if you should add calcium to a tub? My calcium is bottomed out. My Arctic Spa dealer told me very clearly that they don't ever recommend adding calcium to their tubs, that it wasn't necessary.
I have a couple thoughts about your post. The nasty film on the tub after the ahhsome treatment might be "stuff" from the pipes of the new tub. If you sanitized the tub correctly on the first fill, in theory, there shouldn't be any bad stuff surfacing. Regarding your calcium hardness (CH). Softened water has a CH of 0, and that's why we soften water, to get the suds from the soap we use to get clean. Hard water, (high CH), doesn't foam much at all, which is better in the hot tub. In your case, I wouldn't add the softened water to the tub, and then try to bring it back with calcium chloride. I shoot for a CH of 250-300. I hope this makes sense.
