I realy want to make a 50 gallon set.The price of blowers is well more than I want to spend.I want to make it out of stainles steal.What im seing if I buy one like it ,it would be 1000 of dollars EWWW.What im thinking of doing is piping it up with med. grade stainless and running a argon purge and welding it out with tig.And buying a blower from a hot tub thats pushing 110 cf air and seting a dial on it so I could control the air flow.I have seen alot of the different mesh bag set ups and i would just build my own.This should work shouldnt it?
