Reason it was cheap was because it's an older model, not because it was beatup or missing parts. I was just unlucky, someone probably got it for the light and filter media (lol) and returned the rest.
Black box = older; white box = new leds.
The glass itself is worth way more than $27. The filter is an AC20 that costs $20 on Amazon. Still a good deal.
Go get that price check on the black box! Run! They're not marked, but system will show $27 in every Petco.
