Any of that will do fine. I started with 3x650 L/h and now I use 3x2000 L/h.

No opinions on having powerheads that deliver about 700 gph each?
I noticed that the ones that you have, emma, don't deliver more than 300 gph each.
700 gph won't blast my little fishies to the other side of the tank?
P.S. I did decide what setup to create: two XP4's + 2 XP3's, along with the river tank manifold. I just need to get the powerheads to create the flow for the river tank manifold now.

the flow rated from filters is under "ideal" conditions.
you will never have that with the river tank setup.
the important thing is (like mentioned) the powerhead hooks up properly with the tubing.
IMPORTANT!!!!
some sponges have toxins in them. If in doubt buy from your LFS.

I have a 20 L rivertank that's 30" in length and I have an Aquaclear 802/70 that's rated about half that I think? My hillies fight for position right in front of the outlet. It does make it interesting arranging plants and it blows the sand around but I like that. You can arrange rocks and driftwood to create different pockets and sand flows and quiet spots. I think it's fun but depends on what you like.
