Here is a design. I made a "bubbling" manifold out of pvc and connected it to a air pump when I did outdoor grows to bubble 30 gallons at a time. There are a million ways you can design it to fit whatever side container you need with pvc. You dont even need to glue parts together. If you go this route biggest tip I have is use the SMALLEST drill bit you can find. Less than 1/8th if possible. Cheers!
