using a barrel to build k1 filter for 600gal system, will be k1. Set up same as joeys in escence.
I bought a used barrel but it stinks and can't be used, the only new ones I can find at a reasonable price are these, but the top is curved and narrower. Would a uni seal still work on it. As the straight bit lower down would make the water height too low?
Or alternatively what about garden water butt? Would they be any good for this?
