Hello All
As with a few other posts I've seen in here, i'm a total noob at Aquaponics.

My wife and I are looking to setup a 100 gallon fish tank (ok, it's a water trough from a local farm supply store) with plastic cement mixer tubs as grow beds.

We just found a place locally that sells hydroton (thank goodness, shipping the stuff is expensive ), but pea gravel for the grow media was something we had thought of also.

We will be raising the fish for consumption but have not decided on a breed (yellow perch or tilapia ).
My only concern at the moment is the solid fish waste that enters the growing beds. I hear cleaning the growing media is a laborious task, but if not cleaned it could lead to dangerously high ammonia levels. What are others doing regarding this?

Oh, great website and resource center.
