Me too :lol: That's probably why none of my hydro-stone set-ups are as cool as the one in that link. Nowhere near as large either. But one day I hope to build a huge set-up. I get tired of having to let my Pogo colonies loose after only a couple years.Ah, yes! I am planning on building a hydrostone nest. I just have to figure out exactly how? I stink at building stuff!
