+1 on the coffee filters. Low cost way to get the sediment out and prolong the life of the micron filter(s). I have the monolithic ceramic filter kit from cheaperthandirt. Not very expensive and will do the job. I also have two smaller filters for packs. Clorox and pool shock are in the supply as well. I have a well, a metal roof on the house that can quickly be utilized to reclaim rain water, and a creek less than a quarter mile away.
