To clarify further, when I first set up the tub sans snake, one row of holes around the sides was sufficient.

Tubs are easier. It takes me a minute to strip the tub and another minute to fully clean it. Plus, when I have to travel 500 miles all the time, it beats having to lift a tank and take up my back seat. I used to use tanks too, but I was always adjusting things to get everything perfect. I live on a lake, so the weather's always changing here.
