Help. I am new to this. I have a 46gal bow that has been up for about 8 weeks now and a couple weeks ago after I did a water change my protein skimmer quit producing that brown liquid waste, now it just produces clear liquid if anything at all and no bubbles. The cyclone in the skimmer seems less powerful and I can't increase the bubbles or power of the cyclone now matter how much I adjust it. It is a seaclone 100 sitting in my sump. Any suggestions, do I need a new one already?
