Wanted to get some input on a idea I have.I have a couple of cases of barium bags that a cust. of mine returned and I was thinking of using them for a kalk drip.I would mix a 5 gal batch in a seperate poly tank with a bulk head and Poly valve to fill the bag and then hang from inside stand and drip into my return side of refugium.These bags come with tubing and clamps but would have to cut the tip off.If it works I have a several extras if anyone else wants to try.
