I would get a sequestering agent such as Metal Free, Sequasol, Jack's Magic, anything that says "sequeserant" and put enough for the volume of your pool. I would let my pump circulate 24/7, so I wouldn't put any cya in through the filter, however you can put some in a sock and tie it near a return so that it dissolves into the water. You didn't mention what kind of filter you have. You can also cut the leg off a stocking or tights and put it on the skimmer basket to help catch the small particles. Don't take your chlorine up any higher for now until you put in the sequestering agent - you want the metals to bind to the sequestering agent so that the metals will stay in solution. High chlorine plus high ph will have the metals fall out of the water and stain the pool, but the sequestering agent will keep the metals in solution so they won't cause a problem. Keep your ph where it is now, and keep adding enough bleach to stay at 5ppms. The brown water will tend to use up the chlorine fast - especially with no cya. So you will have to test often and keep the chlorine in there - keep the pump running 24/7, vacuum to waste when there is sediment on the bottom and have patience - it will clear up. Feel free to ask any questions you may have. Welcome to the forum!
