it's a 10 gallon tank, when I bought it it includes the filter you see on the left. I wanted a undergravel filter so I bought it along with a penguin 550 (it says it's 145gph). I set it up where the current blow against the plant and doesn't seem like it's bothering the tetras. I really like those black spotted pictus catfish so I'll buy them once the tank finish cylcing.
1) I was wondering if there are too much current? filter on the left and powerhead hidden behind the plant to the right.
2) is there too much plants? they're all live plants by the way
3) my undergravel filter doesn't seem complete. It cames with 2 cheimical filters which requires an air pump... should I get the air pump or do I have more than enough filters already?
