Yup that was me... sold a lot at that meet! You were there?
For equipment I have some big tanks, like 7ft long I think, heavy duty, split into sections like you see at a pet store. I also have my breeder tank which is a custom size 40ish gallon long split into I think 7 sections, I'd have to check. A couple 10 gallons (1 with a glass divider splitting in 2), a 20 tall I think it is. I have a non-drilled 150 with stand too that I never used (was used previously), although I may keep it and drill it some day to use as a reef.
I have some lights, some LED (nothing amazing, off-brand stuff), t5 and standard fluorescent tubes. I have a Reef Octopus 150 skimmer, an 800 watt heater that I may actually just keep as a backup, some 10 gallon LED lids, various parts for skimmers, a small sump, an external pump, stuff like that... I need to clean up/organize my fish room to see what all I have. I think I still have several frozen Larry's Reef Frenzy breeder formula fish food too ha.
