Hey everyone, I'm looking for some suggestions on how to get bobas to work properly on a tank. I use a j-tank, and it works flawlessly, but bobas seems to be a little too thick for it. The cardo just doesn't seem to stay saturated enough. I heard that putting three small holes in the cardo is the best way to go. I can punch them myself, I just want to know the best way before I ruin any cardos. Any advice would be terrific, thanks.
