Would appreciate any viewpoints/suggestions re phosphate levels in pools. Some say I should be very worried about the level (mine looks to be somewhere between 600-800) including my local pool supply folks. Others don't seem to be worried much about phosphate levels. As one source I read said the best thing to do about phosphate levels was to throw my measuring kit away and forget about them. So, we have two extremes and I don't have a clue which is best.
