Hello first time questioning the forum...

CH - 400
CYA - 120
Nearing the first year on this (my first) pool, originally swamp green when we bought the house. We had the seller (attempt) to clear it up before we closed escrow, they got it a cloudy grey after shocking it and flushing the filter... When we got it cleared up (with a shock treatment from a friend of a friend pool guy) we noticed a rather unpleasant grey concrete patch near the middle of the pool (no wonder seller was dragging out getting it clear) and and overall deteriorated surface, crackly, pitted, sand papery, with scaled tiles.
I only had one algae bloom, last summer, and corrected with algicide and store bought shock treatment (I know...) otherwise it's been surprisingly clear all year. Recently added a Sparkling Pool/sink and sweep liquid that helped remove suspended solids left by a few windy weeks then SLAMed the pool and cleaned the filter.
I've been able to keep it clear by using tips from these threads and learned to clean the filter watching YouTube. Until recently, when I was gifted a test kit, I had been using strips to test the water (I know...), which brings me, at last, to my inquiry - now that I know how high my results are how concerned should I be about correcting the High CYA and hardness? Is it urgent, or can it wait 'til the end of summer maybe?
Ps. I am working on lowering the high TA with acid, then aerating.
