If I took the same tank and changed the skimmer to a 302 I then would get watery skimmate if I didn't increase the bio load. Additives such as bonding coral with expoy is going to make the skimmer overflow, kind of like adding soap. I'm not trying to be a know it all, I just know what works.
I order da 302 and they sent me a 303 ..what's the difference?
Should I return it?
As well as lots of bubbles coming out of the bottom of the blue tube. Not sure what the heck happened. I did always have some bubbles coming out the bottom of the tube, but now it's just ridiculous.
I have figured out, that happens to mine every time I do a water change.
