I have three of the penguin 330's and I really like them but the filter
cartridges can get expensive. One filter takes two cartridges and also
has two baskets so that you can add extra carbon. The filter intake
that you were asking about is fairly long, in my bare bottom tank it
only has about an inch or so clearance from the bottm of the tank. In
my cichlid tank (which has gravel) I had to trim the intake tubes down
a bit. Hope this helps!

I have a smaller one. The only filter is the one that slides in behind the
bio-wheel. You're saying this filter requires more?
