Oh yeah, and the bio-balls have been replaced with LR rubble. The mechanical filter sponge and the ceramics are still in there for now too. I'll probably take out the sponge after a while. I'll be upgrading the PH to a Maxi 900 and adding an ebo jager 75w heater. I'm tempted to DIY a MH light canopy for this eventually. What do you guys think?
