Harry, if you are using Excel for a carbon source, I wouldn't worry too
much about surface turbulence. We're talking normal HOB filter
turbulence, and not Jacuzzi jets, right?


I was thinking air bubbles, my wife likes the look of them.

I've got a tank with an air driven sponge filter that I u cel on
(when i remember to add it) and crypts, anubias, bacopa and najas all do
fine. Growth isn't explosive, but I do see benefits from the excel.

Just for curiosity's sake, anybody know what the answer would be if I were
not using flourish excel?
