Yeah, I made a bunch of rock but I didn't love the way it looked. I have 17 lbs of actual live rock in my tank and 20 lbs of texas holey rock/lace rock in it right now. I like the way it looks and seems to be porus and diverse in color. I may use the diy rock in the sump for filtration instead of putting it in the DT. There is a part one and two to that video also on you tube talking more about collecting fish. basically talked me out of buying a flame angel after I saw it! Not even sure if I can buy a non aquacultured fish anymore, well I guess well see tonight because the jungle had a coral beauty I had my eye on last time i was in there!
