Thanks, just checked out your video, looks good! I like your rock scape too. I need to read the advice you received. I'm not sure what all we have. Some hammers, neon green leather, mushrooms...All I can tell you is my wife will spot something she thinks is cool and she buys it. I can't keep up. The 2 rba's we have came from one of the lfs' here in town. They dug them out of the sump we bought both for 20.00 and they are growing fast. Started out about the size of a 50 cent piece. Phosguard/carbon and cheato in the bottom of the 2nd chamber with a cheap 10.00 led light taped to the back. Pretty ghetto but it's working.Love the aquascape .... I think we went a little safe on ours not knowing what we were doing. What are you running in your sump... I am considering a cheato refugium but right now still have the stock basket filter cloth/ phosguard/ Carbon ... what are the inhabitants in your tank are those Nems
