RedSead Max E-170 and water movement.

[scunfcu]

The stock return pump on RedSea Max E-170 cube (24x22x21) doesn't seem to have enough water flow for my SPS frags. Any suggestions for adding powerhead or wave pump?

Thinking of one Jebao RW-4 but worry on reliability. Or maybe Koralia 600 (is this too strong) or Koralia Nano 565?

Have been running all types of jebao on multiple tanks for year now. Ime more reliable than koralia. You'll be amazed by how much water is moved by such a small pump with the rw-4. You'll prob have to leave it on slowest setting so you don't cause a sand storm.
