Just thought id drop a line and tell ya about a few of my products ive been making over hear for a couple years.
Im making aragocrete pieces for reefs and cichlid tanks. I have standard arch's and caves as well as base tables, but we also make custom pieces of rock and a lot of semi custom shapes and sizes.
Our primary rock that got us started in aragocrete rock creations is what we call BioRock(TM). It's basically an aragocrete rock like all others with this one huge difference.... we added a BioMedia core to give up to 1000% more surface area than any natural rock of similar size. From this one rock design we have grown to over 20 common designs and an unlimted(only limited by your own imagination) supply of custom designs. We even made an entire back wall piece for a customers 300g reef setup.
Enough about us though, we mass produce basic caves, arch's, base tables, and of course the BioRocks.......... Below is a picture and a link if you have any questions or would like to see more pictures in our gallery..
