Question about wave makers Nuvo 40

[Nashvegas37128]

I currently have two tunze power heads, one on each side. I am looking into a better choice for wave makers and was wondering if a Nero 5 would be a best option as an upgrade? Would 1 be enough?

Thanks in advance

I LOVE my Jebao SLW-10. Extremely powerful for my 25, dead silent (like it's hard to actually hear it *at all* in a quiet room, quiet), and adding another one won't even come close to breaking the bank.
