The stuff grows so slowly it has the same problem as Java moss for vendors. If you have the patience though it can be a very fun filling plant to a tank.
I would like some kind of check valve so an aqua clear doesn't loose siphon if the power goes out, but it needs to also not clog since it would only have a pre filter at best to catch anything that goes through it
I have never understood this theory just based on the food. Look at how the red krill flake or hikari vibra bites makes every fish go nuts. I feel that's been a misconception if the all those foods come in red then you would think they would be a much slower response time.
