Indicates no flooding or conditions that would worsen water.
Filter housing (1''x3' clear tubing), gravel, and 5.6grams of unrusted iron filings obtained today. Prerusted iron nails will no longer be used. Instead, iron filings will be rusted and placed at the top of filter. Filings will be rusted by moisturizing with water and also appling table salt. Ratio of solution not yet determined. Challenges may include separating the filings from the salt. While water can be evaporated, salt will remain.
Fiberglass insulation, rubber hose, and possibly a bottom cap will be purchased on Friday and filter will be assembled over weekend. Base and sheath to be determined.
