With a pool in the condition yours is in, there is no quick fix. Even if draining it dry was an option (its not, it will ruin the liner) manually cleaning it out would take time. More often than not, those "magic elixir" solutions end up making the problem worse. Your pool did not get in this state overnight, it will take longer than overnight to fix it. We have thread after thread where someone with a swamp-pool asked a pool company to clean it up. They throw in all their magic hoo-haw and end up walking away from the job a week or two later because they can't get it clean. In the mean time they have raised the CYA to astronomical levels or added enough copper to the pool to cause stains and you end up having to do a series of drain and refill cycles to safely exchange the water in your pool.
By now you know how important it is to test and balance the chemicals and keep them in balance. It is temping to try a "magic elixir" to see if it will work, but before you do read the labels. If it contains minerals (copper, silver, ect) you don't want it in your pool. If is is just a mega dose of stabilized chlorine (dichlor/trichlor or Calcium Hypochlorite) not only do you not want it in your pool, but you are already giving a mega dose of chlorine when you slam, and your doing it without adding CYA or Calcium that you don't need. If the active ingredient is something you haven't heard of look it up, you probably don't want it in your pool. If it says "proprietary formula" don't use it. Never add a chemical to the pool that you can't identify.
My advise is stay on the slam, raising back to slam levels as often as you can and be patient. Keep that pump going 24-7 until the pool is clear. Your patience will pay off in the end.
