Hi Pete, there are a few ways you could go with this. If you want to use controllable pumps, then two 6105s with a 7096 controller would be a good choice. If you plan to have a lot of SPS or just want extra movement, then adding a Wavebox to those would be suggested.
If you don't require controllability and don't plan on the tank being SPS-dominant, then two 6125s should suffice.
