What size Tunze pumps?

What size Tunze pumps would you recommend for a 90 gallon AGA tank? I seem to have a dead spot and I currently have four maxi-Jet power heads on a Red Sea Wave Maker Pro. Are the pumps too strong for that size tank?

If you want to complete replace what you have I would get a 6000 and a single controller. If you just want a supplement I would get a 6060 and get rid of two maxijets, you cannot run the Streams on your wavemake- it will ruin them. It shouldn't be too much, but if you go with the 6060 I would keep two of your maxis just to keep some random flow.
