Hi folks, Thanks for helping a newbie. I just got my two bell siphons set up, and they're working great (besides some hydroton getting underneath the guard and sucked down to the tank).

My question is this: My grow beds are filling up and draining every 7 minutes (=8.5x per hour). Is that too frequent? Will that cause root rot? Should I go buy a smaller water pump?

Thanks for the help.
