Hey guys need some help deciding on a filter to get for a 29 gallon. It will be lightly/moderately planted with low-light plants. I was basically narrowing it down to an AquaClear Power Filter 50 which I could get for $45 (didn't have next bigger model in store) or Fluval C4 (possibly C3?) for $48. I eliminated the Marineland Penguin from some reviews I read about it and the fact that it would only be about $7-10 less than these other two. I read that the GPH should be about 8-10x's the gallons your tank can hold. Isn't that a bit overkill if it says it can handle a tank up to double my current size? I was just wondering as I don't want to be cheap, but I also don't want to have an overkill filter as I don't have very much money to spend on a tank I know I will be upgrading in a few more years. Thank you!
