Alright...So two days ago, I went out and bought an fx5 for my 125.
There are a couple problems with it right now...#1, my stand isnt tall enough for it. It JUST fits in, and the hoses are under strain from the top of the stand. So my dad suggested drilling two holes in the top of the stand, where its just a piece of plywood, so the hoses can run freely. Good idea? Or will the tank fall to bits?
Second thing is, the intake goes far too low in the tank...So how should I get it higher? The tubing is already taught, but there's a big straight piece that goes into the water. Should I cut that to size?
The filter is working wonders for my tank though. For the past two years, I've had a reallllyyyyyy crappy HOB filter that did nothing.
Happy to know I'm providing good filtration for my fish. 
What I'm planning on doing is putting a large piece of driftwood the length of the tank in...And then lightly planting it around it on each end and maybe some java moss on the driftwood itself?
Input welcome
