>>2588521anyone ever experiment with making a crude pre-filter? i have a fish tank so i was thinking of having some plastic straws on hand and making a charcol filter rig that would serve as something semi-disposible before a real filtration like this:
https://www.kaviso.com/products/katadyn-befree-3l-water-filtration-systemi dunno maybe like cotton balls at the bottom and fish tank charcol on top just to get major sediment out and preserve the life of the higher quality filtration system.
any thoughts?
