OK, I have always had a small (very small) pond everywhere I have lived. Always cobbled together without much planning or purchasing. I have a small pond here (110 g) that needs a water fall box/ filter. I am not going to try to make one. I found a small one online but the fitting says its 1.5 female. The pump I want to reuse has, I think a half inch male outlet. What do I need to buy to make this work correctly? I also need some tubing. I should know but I simply have never used this stuff before.
