Brian not trying to start an argument with u but after doing some more research on scrubbies and asked a friend who uses them I don't know where your getting your #'s from. To fill a 1 gallon bucket with scrubbies would be more like 15-20 max. Also who ever pays 6 bux for a gallon of them is getting ripped off as my friend buys them in packs of 10 for 1 dollar at the dollar store. Buy them in bulk would a lot cheaper. My friend filled up a fluval 404 to the max with 30+ scrubbies(3" diameter) and a fluval 404 has a volume capacity of 8.5L. 3 dollars for 2+ gallons of scrubbies is definitely cheaper then 7 bux a gallon of Bioballs. When u said the price wasn't much of a difference between the two got me thinking...hmm it doesn't make sense. Lol.
