Hi all. I've worked out my tank display. Betta 1000. Is around 300 ltrs. So I'm Planing on two hydor evolution 4. 4000 ltr an hour each. I like the idea of the wavemaker to go with them. And have them come on one at a time say 5 mins each. My question is. With the return, witch is powered by a newjet 3000, do you think one hydor on at a time will create enough flow.
