Lookn good how many Liter/Hr is that air pump? Have you considered getting the ceramic diffusers? They are a bit pricey, but make tiny bubbles and last years longer. They are easier to clean and have a tendency to clog less. Just some thoughts, as I'm sure you've learned DWC is all about your air system. Good luck, bagseeds really are a waste of time huh? lol it's cool their fun to torture and learn from.
