Had to replace our sand and pump. I was told to floc the pool so I did that last night but it doesn't appear to have done anything. I was reading floc can gunk up your filter which is why you vacuum on waste. I'm concerned if I turn it to filter I'll gunk up my brand new sand. Picture of pool currently. Alkalinity is perfect, PH is a tiny bit low. What are my next steps here. I don't want to mess it up since I just replaced sand and pump but I need to know where to go from here to get it clear.
