over-filtering a combatant against overstocking?
my buddy and i got into a bit of an argument about this one and we just dont know who won lol

my tank (29G) hasa 55G rated filter and he thinks that that compensates for having more fish than the 1 inch rule. so i am wondering what your thoughts are.... or rather what the truths are.

A lot of filters are overrated so you may not be able to get 55g worth. You may want to check this thread out:

Well both of you lose and both of you win.

If oyu are overfiltering with an Aqua View or other cheap filter then you might have just barely gotten to the needed filtration rate for the tank you have it on. If you have a higher end HOB then over filtering could very well help with overstocking as far as waste production. Same goes for cheap canister filters and high end ones.

Now this does not mean that filtering a 50 gallon tank with a filter for a 200 is going to make it ok to stock with 4 inches per gallon. No amount of filtering will do that.

Also, a 14 inch Oscar in a 45 is all you are going to be able to put in there, period reagrdless of how much filtraiton you have.

There are really too many factors to simply say: I have twice as much filtration, so can I have twice as many fish.

thanks guys.

so far in the tank there is a dojo loach, 3 albino tigers, and 2 blood parrots. i was hoping to add a few more tigers and a couple of cats to do some clean up work on the bottom.

a lot of it depends on the ammount of biological filtration you have, since that is what handles the overall bioload of your tank. More biological material will allow you to overstock a little and i've personally done that in the past.
