Undecided need some input for new tank?

[kien]

Oh, I will add that although my 120g basement tank was isolated and took more time to maintain that having it set up this way ultimately saved by main 150f from disaster! I was a little lazy on the basement tank so didn't dip stuff properly and also took in questionable fish. I ended up getting hit with velvet an all manner of pests like flatworms in that tank! If it was not isolated my main 150g would have been hosed as well.
