What can I do to make the liner getting more stains? Water is still quite clear or like 96% visibility at least for now.. I put in phos free a few days ago. 4ft to 12 ft depth. I also put in metal free 2 weeks ago along with The purple stuff or magenta stuff. If water is clear no clarifier is needed right or algecide? As when I brush the sides a little I see some powdery things sweeping away.. like very very light maybe greenish. Do I need Algecide. Seems like it is some greenish or light greyish dust when I brush the bottom or sides of the pool. Do I need to suck this out to waste?
