Before I know about AQ and all the great LFS, I bought my equipments from eBay stores that are ship over from HK. Got this super quiet Teion 1000 air pump and it have been running for a few months and it is still as quiet as day 1. Sometimes you got to feel it to check if it is running. Currently it is running on the sump of my main display tank.

Need to get another one for my quarantine/hospital tank as my Big Boy one is fault and very noisy. Does anyone know if I can get this Teion 1000 locally. Checking here before I go on a wild hunt or order from eBay again.
