Hi, my SPS mixed tank is 36" x 20" x 20". Currently I am using Newjet and Maxijet pumps with timers for flow making. The old school way:

A pump is placed on the left hand side of the tank, and the other right hand side.
Timers are set with 6 hours interval, to stimulate high tide and low tide.
First 6hrs, left pump on, right pump off.
Second 6hrs, left pump off, right pump on.
.......
There are overlapping time in between, that both pumps turn on, or off.

It has been working for years. I am thinking of upgrading the Newjet and Maxijet pumps with better one with more complex wave patterns. But I want to keep this time pattern setting. What options do I have?

I have checked out Tunze, and I like them. The new one all have a single controller included, but it only controls the wave pattern without timer.

ps: I dont like MP40 as I like to hide my pumps behind rocks and to adjust the flow direction.

Thanks.

A tunze 6105 on a single controller can create short interval "pulses" that will be far more ideal than your current setup IMO. Changing current every six hours isn't really the best interval, you want a pump or pumps that will ramp up and down every 5-10 seconds.
If it were me, I would get a 6105 Tunze with the broad nozzle and a sureflow mod kit for one of your maxijets. Have the tunze on a 5-10sec pulse, and have the maxi on a timer to run intermittently.

However, there is an age old saying if it ain't broke then don't fix it. However, I ran a similar setup in my old 58gal with a Tunze 6101 and couldn't have been happier.
