Question about filtration

[Anaxus]

I have a 29 gallon tank and will be getting a pair of convicts. I got the aquarium kit from walmart which comes with a aqua tech 20-40. But when I opened the box there was a free upgrade to a aqua tech 30-60 which is rated for up to 75 gallon tanks. I think it is about 300gph. I am planning on buying the parts to upgrade (http://www.*****************/information/bio-wheel_filters_2.htm#fishyfred) it to a penguin 330 which would give it two bio wheels.
Originally I was going to use a eheim canister filter along with the 20-40(rated for up to 30 gallons). But now that it has the larger filter will just the "penguin 330" be enough filtration for two convicts? Or should I still hook up the canister filter. I know people say there isnt a such thing as to much filtration but I don't want the gph to be too large. I am not too sure which model the eheim filter is but I think its 2211 which is about 120 gph.
So would ~ 420 gph be to much?

That penguin 330 with biowheeels is enough for your current tank..if you ever decide to buy a larger tank, which I'm sure you will someday, then you can buy an Eheim canister filter...and one of the larger ones at that.

I was wanting to get a 55 gallon but dont have the space atm. I already have the eheim canister filter from a previous tank so I was just wondering if I should add it with penguin 330 or not.

I have a 29 gallon with con's and only have a AC200 for filtration and it works fine and has been since october.

Ok I will just use the penguin 330 on it and save the electricity :cool:
Thanks for the advice

yep, in my 29 I only have about 240 gph, is biological, and does a great job I might add. You should be able to get good flow with the 330, just make sure you keep the spouts cleaned! :D
