OK.. so here is the cross view of the build... I need some advice/feedback in specific the waterfall/waterline.
The orange line is the netting to keeo the substrate out of the water. In essence I would have a small pond that is filled with pebbles that is on the same level as the hydroton. thus the water will circulate nicely and I can monitor the waterlevel with ease... the pebbles will be there for gecko safety
