I have a 3 ft long 45 gallon reef tank and need some flow recommendations. I currently have 2 565 GPH Koralias at the top of the tank pointed at each other and my flow is decent but I think it should be better. I have xenia at the bottom of the tank and some GSP mid level and both seem to be doing great with the current flow, good movement but not too much. I recently added a frogspawn mid level in the tank, it is extending during the day and sways a little occasionally but I'm thinking it needs more flow. What do you guys recommend for flow on a tank this size? Should I add 1 larger Mover, MP10/MP40 or Nero 5 on one side of the tank and keep a 565 Koralia on the other or should I remove both Koralias and add 1 larger powerhead?
