Hello- I'm a newbie with this...My question is I have a 7" deep grow bed (for now) - looking to grow spinach. I'm thinking of using river gravel in the bed and then peat moss on the very top (is that ok?). I'd like to know how tall I should have the bell siphon for top level and then how much I should leave for low level. Thanks for your suggestions!

Welcome to the forum.
Ideally you would not want water level to remain 1-2 inches below the top of your medium.
This prevents algae growth
If you have not read Oliver's 101 thread...I would highly recommend it.....
Looking forward to hearing more about your system and also....WE LIKE PICS!!!
