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?

, 2 . U can never have to many real plants so thats fine having all them it provids food for certain fish too. 3 . if u wan to get the air pump u can but i think with those undergravel filter u can attach a straw like thing to the pump which goes from the outside of the the tank to the filter and sucks air in from the outside which makes bubbles!!
