I'm not sure why but this year I've been struggling to keep my water crystal clear/blue. Literally every morning I have a layer of what looks to be brown algae completely covering the pool floor. I have brushed, vacuumed, brushed again, vacuumed, backwashed, rinsed, and adequately shocked the pool multiple times but can't seem to get that algae out nor the water from having a green tint. All my other levels are up to par
pH - 7.4
CC - has been high from the shock
FC - .3
Alk - 80
CH - 250
CYA - 30-40 range
My pool filter is like new, the sand was just replaced last season. We just bought a new 1HP Hayward pump to replace our old 1HP Hayward pump.
I've attached a pic of what it looks like at the moment and what the bottom looks like when brushing. In years past, I've only had to get my levels where they need to be and then just maintain the pool with liquid chlorine/bleach every day.
Any ideas/insight is greatly appreciated!
