OK second attempt since the spell check messed up what I had just typed.
I was looking around and found that know one has yet done any post in regards to there nano tanks so I fig id be the first one to post.
I decided to go with one of my nanos for now. The cube master.
Upgrades are as followed:
Pre filter pad: It was a cheap little cotton looking thing. I replaced it with a heavy duty pre filter pad.
Return pump: Was a no name company. I replaced with a Rio 800.
Return nozzle: Stander direction adjuster. I replaced with a 360º wave maker.
And this is what I have after 3 months.
sa edit: corrected image links
