So, I've also been researching on flow. My tank needs to rid the hot mags and i need to get 2 more powerheads. Currently I got 2 maxijet 1200s. What kind of wavemaker timer is best? All the reports from people online say things like the Red Sea wavemaster pro dies after 1 yr and the cheaper coralife power timers die after 6 mo. What does everyone here do to alternate the flow current in their tank? What have you found that works well?????
