Default why not undergravel

If you simply use deeper gravel, the water will not flow well through
it, and you've defeated the function of the UG anyway. Best filter for a
planted tank is generally agreed upon to be the canister type.


I haven't seen a canister filter specifically for aquarium use. I
imagine this is the most expensive route as well. I can immediately
think of one obvious advantage: you have an additional few gallons of
water.

I am picturing something like a Katadyn flow thru filter, with homemade
fittings and a pump, built into a 5 gallon bucket. Even homemade, what
I'm thinking of would easily cost a couple hundred bucks. But the water
on the output side would be safe to drink...

Seems like overkill. I'm stuck with my choices for the time being. I
think my gravel is deep enough, and I guess I have plenty of filtration
from the charcoal filter. My fish seem to like bubbles... Like I
said, it's cranked way, way down anyway. I hadn't thought of the roots
being a problem, and it hadn't occurred to me that they would ever have
to move.

Thanks!
