Buying active filters

[GNarnian]

Hey all I just had a quick question. I'm setting up my 120 gallon tank this weekend, and I want to get some of the active filter sponges to get a jump on the cycling.

For my 120 tank I have a Fluval fx5 canister filter. How many filters from angelsplus would you recommend I buy?

Anybody? Any idea? Im planning on buying them tonight, but I don't want to buy too few or too many!

I would say go with 2 of the 4 inch and cut them up when you get them...

Okay thanks!
