So I am wondering about filtration...I am setting up a 33 gallon for 2 goldfish. I originally was filtering with a filter that says it filters 200 gallons/hour (for aquariums up to 50 gallons). Since I realize how messy the golfish are and that I am stretching it with the 33 gallon, should I instead get a filter that filters 350 gallons/hour (for aquariums up to 75 gallon). Is it possible to overfilter??
Can you overfilter?

I dont see why that woudl be a problem. The more filtartion the better! As long as your fish can handle the current.
Ive read 10 times filtration but i think its more to do with needing more media than anything else. You dont want to turn your tank into a washing machine for them. 10 times is good but look for filters with lots of media and if theres too much current then use ornaments to slow the flow a bit or use spray bars.
You need an area of the tank where the water is calm so the fish can chill out and sleep.

Most people do with filtration that can cycle that tank water 10x in an hour.
For example, for a 50 gal tank, most will go with a filter that can do 500 gallons per hour. The problem that you should watch out for though, as already stated, is to avoid creating a current that is too strong for the fish as this may lead to exhaustion in their part. What I'm trying to say is that there is no problem with overfiltration, but there would be a problem if the current generated is too strong. Pretty much what fantail and import just said. Good luck

I agree with the 10x an hour rule. I run two Emperor 280's on my 55g, so I'm just over 10x. I have the intake depth high on the right side of the tank and low on the left side and it's a great balance of filtration and water flow.
Having kept two goldfish in a 29g tank for years and never having a single problem, I would have to disagree with you there.
My blackmoor likes to play in the bubbles of the ornamental bubbler! Every now & again he goes to the source of the bubbles & lets the bubbles take him upwards! Then swims back down fast & does it again! He seems very playful round the bubbles but the other 3 just leave them alone... Its great how they all seem to have different personalities..

Were they fancy goldfish or long bodied? 2 long bodied regular goldfish should be able to live for 20+ years and get to be over 12 inches if not 18 inches long. So if yours didn't get there then your argument about a 29 gallon tank isn't a good one.
