Just bought this (February 2017) and filled it with water Yesterday. I have rocks in it and cycling at this time, No sand yet. having a change of heart about AIO now contemplating having a sump (would like to get APEX in the future) - anyway - if there's anyone interested - I'm selling it for $1100 ... tank stand, skimmer, return pump and Hydra 26 HD LED, before I start putting sand lol. thanks! Lights is hanging but NOT used - have not plugged them yet. (rocks not included - they are dead anyway)
