If your oxygen is marginal or the water flow ceases, the oxygen will deplete much faster. Don’t chase that comment on denser media. Not many old timers bother with Matalla. It’s appears to be something that’s more profitable for dealers. And J-mat is cheaper.

Now that Russell has straghtened everyone out on the "facts" surrounding cost and square ft/cubic ft ratios, maybe some MORE old timers would want to switch. This old timer is currently using both. I will be replacing the J-mat in my bio tank on my main pond this fall/winter.
