HOB flow rate

Recommended Posts

What's the minimum flow rate i can get away with on a 2' x 16" x 14" tank?

 

i was looking at the AC range, but i feel that the 500 is just too expensive.

 

One that i do like the look of is a Supreme Aqua Bio Filter ( 1000lph )... is that too little or would that be sufficient? there will also be a powerhead or 2 in the tank for movement. this is just purely for bio filtration purposes (prob just have a pre-filter sponge or course filter sponge only)

 

Cheers,

Grace

I was told that for a 10gallon I probably should aim for about 100gph (... close to 380lph I think) but the guy could of just been pulling that out of his ass.

depends on what you want to keep. some coral don't like much flow at all. if you already have 2 powerheads, you'll need to calculate that into the equation. i think the beginner articles from this site says 7-10x flow. as you know lr is your source of biofiltration, but using the sponges as supplimental biofiltration can lead to problems.
