Is a low Cal a problem for a vinyl pool?

Cal 20!!!
Cya 40
Temp 80
I hadn't measured Calcium hardness in a while but I was quite surprised to find it that low. I had been battling iron stains and have added some heavy doses of iron/mineral sequestrant. Otherwise it's been BBB (Tri-Chlor earlier in the season until the Cya got to ~40).
The pool looks good. The water is clear and the iron stains are gone (for now).
