He! He!.... if I can get a foot in the door...... After all these years,...... I maintain!!!!..... Undergravel filters... that covers at least 1/3 of the floor area..... remains my favourite...... I have run tanks for 8 years plus.... exclussively on undergravel........
Whats ur price range fluval is the way to go. I can link you a canister that sit in the cabinet your tank is on that way it bumps up the stocking level of the 10g alittle or a fluval in tank filter is always good they both offer much more filtration then the standard filter.
I've had success with the Aqua One AquaClear range. I'd recommend getting the next size up from the one recommended for your size tank as they aren't the most powerful. They're very quite though.
I've had 3 aqua clears and while I love how well they filter, they have never lasted do than 6 months. I love my marine land emperor,it's quiet and has lasted 4 years and is still going strong
