Yesterday I bought a Bio Wheel 170gph filter for my 29g tank. I think I remember seeing someone here say goldfish need their water filtered 10 times an hour, so that would leave me with another 120 gph to filter. What's my best bet - another Bio Wheel, I guess the 125? Would there be any reason to use a different type of filter, like a Fluval internal filter, seeing as how the Bio Wheel should be low maintenance?

Seeing as how my fish are still pretty small - both are less than 2" long - how urgent would it be for me to add more filtration?

Also, we had bought a Perfect-a-Lite hood but it doesn't accommodate the filter very well. Any suggestions for a hood that would work better with the filter(s)?

Thanks!!

I will let someone else anwser the filter question. Bus, as for the hood, does it have a flat back piece that could be snipped of in areas to make a better hole for the filter. This is what I did with my hood.

you could put a aquclear 200 on avery good filter and easy to clean

i used a dremmil tool to cut my hood up to accomodate my second filter, it cut through it like a hot knife through butter.... =)

You have 2 2" fish in a 29 gal? If that's the case, your current filtration level will likely be fine for awhile. There's no reason you have to use a different type of filter - another biowheel would be just fine. If you'd like to use another brand/type, though, that's certainly alright as well. Canisters usually provide more suction power, and they only need a small opening in the back of the hood.

wow 10 times an hour? I've been told by 2 fish shops that you should filter 2.5 times your tank's volume per hour, not 10! Then again - there really is no harm in overfiltering (except my poor tetra's got sucked into a really powerful filter i got)

People here tend to recommend 10 times per hour *for goldfish* because they are such messy fish. And unlike tiny tetras, unless they are big enough not to get sucked in by the more powerful filter
