Problem using 5 gallon buckets for cloners is you need to have a lot of water in the bucket and a lot of bubbles. Try a test run and see how high the bubble wet the area. Average bubbles only reach about 12" or so fyi. less then that and you don't get enough of them or you just don't place the air stones in the bottom. Something to think about anyway.

He put it up last night check it out. I can save you a few bucks just let me know if you want one or not.
