Rock isn't glued together simply because I'm not 100% sure that I'll like this scape later down the road. I've already decided to pull the sump and re-do it, so the chances of changing up the rock work are very high. Once I settle on a good combo, I'll probably put a little epoxy in for good measure. It's really stable though, even if it doesn't look it. I fit ever piece in to make sure that it held good.
I've looked at the apex, but I really like how the RKL/RKE is set up. It seems more user friendly, and has free software. It also has the ability to connect in to the internet, though I've not gotten that far in to my research. I actually started a thread on controllers in the hardware/equipment forum to weigh out my options. Any input you have there would be appreciated.
I found a guy who will sell me LR for $3/lb... the only LFS that has LR locally sells it for $12.99/lb and it is COVERED in hair algae and who knows what else.
On an unrelated note, my tank has evaporated 15 gallons in 7 days. There aren't any leaks (trust me, I have looked), which is why I find it very odd that it's evaporating that much. My total volume is somewhere between 50 and 55 gallons. My fw tanks in the basement don't evap nearly that much!
