Pump advice for 60g tank

So I think I have a bit of a dilemma with the pumps I currently have. I had a 36g bow front tank and at the time I was replacing the equipment in it with the idea that I would be going to at least a 100g tank. Well instead of going that big I got a heck of a deal on a Deep Blue Professional 60g frag tank with stand and couldn't pass it up.



Currently I have 2 Tunze 6095 pumps. I run them with the 12v jumper in "Reef Crest" mode, using a controller, one pump never gets above 70% while the other never gets below 30%. This is about as slow as I can go without doing custom code in the Reef Angel controller.



Since the Tunze pumps stick out so far in to the tank and the fact that the tank is only 12" deep I can't seem to get good pump placement without blasting coral or moving a bunch of sand. I have tried putting the pumps on the back of the tank pointed to the center of the glass and this was ok except the sand at the front of the tank was blown all over. I have tried putting the pumps in the center of the sides blowing at each other but this was too much flow where the pumps flow collided. I tried putting the pumps offset each other on the side, 1 towards the front and one towards the back. That pretty much created a whirlpool type effect which wasn't all bad but the coral didn't seem to like it. Lastly, and currently the pumps are mounted towards the front of the tank pointed at each other but angled slightly to the back of the tank. This seemed to make the coral happy and allow me to keep the pumps at the speed I want. The down side is that the back corners seem to have a bit of a dead spot.



So after my troubles with the pumps I was wondering if it would be advantageous to switch to 2 Vortech MP10wes pumps. These pumps wouldn't stick so far out in to the tank and have a pretty broad flow. Also since they have a lower low end the range of usable flow is better for me. My only concern is that the tank is 4ft and the MP10 won't reach the other side.



If anyone runs Tunze or Vortech pumps on a similar sized tank, or even a shallow tank I'd like to know how you have your pumps setup.



As for coral I have Ricordia, 1 SPS colony, finger leather, zoas, hammer coral, frogspawn, 2 acans, gsp colony, candy coral

Here is a full tank shot. Frogspawn has since been moved to the far right, the pumps are on the sides towards the front, and the SPS colony was moved to the higher rock on the left.







Thanks for reading!



TL;DR version - Should I switch from 2 Tunze 6095 pumps (12v jumper 30%-70% speed) to 2 Vortech MP10wes pumps on a 60g frag tank.
