Garofoli Big Fish Posts: 337 Kudos: 143 Votes: 27 Registered: 12-Apr-2006	I hae a 10g tank with a 100 Bio-wheel, Would a 100 Bio-Wheel w/ an undergravel filter work well for a crowded 30g Cichlid Tank? Whats the basic ruling on ow many gph to amount of gallons? Thanks. Chris

The "Rule of Thumb" is 4 times the capacity of the system. Here is a link detailing this information: [link]http://www.hagen.com/pdf/aquatic/bag.pdf [/link] Also, though I could not make the link work, if you type "aquarium filtration GPH rule of thumb" and search, you will find and article from DrsFosterSmith among the results that is very informative.

I like to have my turnover rates nearer to 7x. A 100gph on a 30 gallon tank, especially full of dirty cichlids isn't all that great if you ask me... I'd bump it up a bit for the health of the fish.
