Did you see the lamps with the corals in it? The 'terrarium lamps". So if I put a Pc bulb on the lamp do ya think it'll be a nice little nano reef for shrooms and soft corals?
The tanks are installed by AquaticVision based in Huntington Beach, CA. CostCo also sells tank maintenance service performed by AquaticVision. My guess is that AquaticVision subcontracts the service work out to local stores and hose suckers throughout the US much in the same way that Marineland subcontracts work out for their lobster tank service calls.
