Need help on choosing more flow

[chark]

I need to add more flow. I have a 60 x 30 24inch High and 3/4inch thick glass tank and an overflow in the center back. I currently have a wavebox and 3 K4's. I would like to switch to Tunze and would like help on the upgrade. I was thinking about adding 2 6135's. Due to cost but would just wait longer if it cost more.
1)Would 2 6105's have better flow?
2)Is there an advantage to controllable pumps since I already have a wavebox?
3)The actual thickness of the glass is actually less than 3/4 inch would the magnets to 0.74 work well on that thick of glass?
4)Any suggestions on placement? I was thinking of attaching them to the center overflow and pointing them to the sides.

Hello Chark, 2 6105 will be a good start but what are you keeping in your tank? If softies, you are ok with 2x6105 but SPS, you will need to add more in the future. My theory is to make one time purchase and get it over with. I would suggest 2x6205 and the controller. You can mount the pump at each corner on the back wall and flow across the tank on interval 2. The wavebox produce wave motion but not directional flow therefore random directional flow is great for all the live stock you have in your tank. You will be fine with the magnet just be very careful and do not let your finger stuck in the middle

I have a mixture of sps and lps. They are all small now but they will grow. Why use controlled pumps compared to the uncontrolled?

Controller pump on pulse mode will provide random directional flow plus the controllable series produce much more flow compare to the non controllable.

The magnets will be fine, you probably don't need the 6105's but they are nice in that you can lower the flow if the flow is too much, that isn't an option with the 6125. The main reason I would choose the 6105 is you probably will need less flow now and more as the corals grow so you can turn them down and increase to full power as things grow in.
