I just got 2 koralia 3's to replace my 4 MJ1200's that where on a Wavemaster Pro. I have read that the wavemaster was compatible w/the koralia powerheads after you insert a piece of airline tubing to quite em down. The airline tubing did make one of em way quieter but now they both have a tendency to start in reverse! One pump still clicks away at start-up. Can anyone help?
