Mavjoy you may want to add more powerheads depending on what you're planning to keep in the tank long-term. In my 10g I started with just a return pump for flow.. then added a "
PowerSweep 212"
(junk in my eyes) then added a Koralia Nano.... later added another Koralia Nano and then later swapped out 1 Koralia Nano for a Koralia #1
So to sum up what I have now..
1x MJ600 160gph (return) (pumping into DT from HB Fuge)
1x Koralia Nano 240 gph (front left corner pointing across tank to right rear)
1x Koralia #1 400 gph (front right corner pointing across and down to lower left corner)
This is a total of approximately
800 gph in the main tank. The humor is I'll probably add one more Koralia just for more "uuummph" in the near future.
You want to decide what you want to keep long term and plan your "flow" accordingly.. some corals can't get enough flow and some like medium to low flow.... for me.. I can't get enough flow
