I have 2 Klaes Juniors running on 2 different reef tanks - one is working very well, but the other is not, despite having been taken apart and cleaned. When the input is increased, it produces a watery foam, and when I cut down on the input, not enough foam is produced. Do you have any suggestions as to how I could resolve this problem? Thanks.
