new on the forum, thought i'd start my first thread...
would you buy 2nd hand aquarium equipment? if not, why? i've heard stories of contaminated and diseased tanks, but surely these can be cleaned out properly (very much doubt a seller would admit to it anyway unless you knew them).
what about filters etc? at times you can see some really good deals on high-end eheims on ebay...
any advice or pearls of wisdom welcome!

thank you
