ebay

I have a eheim pro II and I'm looking for supplemental filtration. I'm tempted to get a cheap one off ebay. I can get a 100g (300goh) for $50. Are they more trouble than they are worth?

I just won this auction on Ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rt=nc&nma=true&item=110633237215&si=nnQcliurkCbgq93dbU55vRv0S6E%253D&viewitem=&sspagename=STRK%3AMEWNX%3AIT I got the light for half retail price with shipping. I only bid in the last 30 seconds. Anything else is...
