@DrPack, thank you! I use the standard cylindrical air stones that come with majority of the current culture systems. Disk diffusers are also cool and sleek. I like the look at them but I don’t know if there is a performance difference between the two.

Your setup looks great, which air stones are you using in those buckets? I've been wondering about replacing regular Larg air stones with the Current Culture Diffusers. Not sure if it's worth the expense.
