although this is a 70 gallon 'Rubbermade' stock tank the general design is applicable to all stocktanks.. now rubber made stock tanks come with a teired design so there is already a ledge to support you bottom grate.. with some of the off brands you may have to build a pvc framed support for your bottom grid. all the plumbing (pipe and fittings) used in this construction is standard 1&1/2" pvc... i built some risers to hold my bottom swirl assembly pipes off the ground 4" this is by no means a neccessity, many people build theirs with them resting on the floor of tank. i also built a waterfall weir for mine which is by no means the standard...most people use a shower drain or a closet flange (toiltet drain assembly) for their outlets. also the original "skippy" filter does not have a flush valve. although it may very well be "not neccessary" its a good option to have available, as it eliminates fecal and other bio matter from the system,lessening the filters work load, and making it more efficient.. that said i hope this thread is easier to folow than the other one on this build... when complete it can be put pondside and giver a low profile waterfall like this:
