Due to poor planning when I set up my tank I had a big pile of rocks that mostly blocked the view of the short side of my 3’x2’ tank. So I ordered a bonsai/epoxy resin rock thing from West Mariculture. I replaced about 1/3 of the rock in my tank with this structure. I like the look so far. I had to cut the bases of a few across and mount them to flat frag squares, sucks to lose growth, but the rocks had to go. I didn’t take a before pic ( just rocks agains the glass) but here is the structure and final product. Man, there was SO MUCH detritus and under the rocks, even though my tank is BB, it still built up like mad. I did a WC and out a filter rock on the drain, but it not all gone yet so excuse the haze.
