Yeah just my nexus 4. I just remembered that my mother has a bridge camera so will have to have a go with that on a tripod.
The bare bottom approach is working well I think. Seeing all the waste is an eye opener for sure. Also is nice not having the sand blow everywhere. Ive got a big flat piece of gsp that I'm going to glue to the exposed glass as I think it would be cool to grow that across the bottom, maybe with some mushrooms and ricordia intertwined.
I need to set up a sort of spay bar at the back of my egg crate though as currently all the detritus gathers right at the back making removal more awkward than it should be. I think half the trouble is my return hits the front glass and pushes everything under. I may play around with the return first as I imagine the spay bar will clog.
Its all a learning curve
