well both lights are out, niche looks clear, will leave them out for the rest of the slam. I know why they say it's easier to maintain the water than fighting algae...
City water with water softener. I had it tested came back at .5 iron..I think they said very low.
then I better star bringing that up, never seen it that low...No, the SLAM should not affect the CYA test.
Remember, the lower the CYA the more effective the chlorine. I would hold off on messing with the CYA or any other parameter during the SLAM and concentrate on the SLAM. Once the water is clear you can worry about CYA. I bet algae is reducing the FC more than UV is with algae in the water.then I better star bringing that up, never seen it that low...

Plus, if it was 80 before and 0 now something else is up - testing error?
when I am back to normal pool readings, my spa drain which really doesn't get much circulation through it, would it be wise to drill a little hole in the valve like they do in the solar valve just to have a little circulation through it?Great!
