Hi everyone! Love Reef Central, lots of great info...
It's been 20+ years since my last Reef setup and I am now back into the hobby.
Looking for some help.
I recently setup a 65-Gal with a sump under (Bio Balls and Bio Plate) and a Sicce 3.5 return pump with hard plumbing between the Tank and Sump. Eshopps Eclipse S overflow and a couple of Jebao PP4's.
Everything went well cycling the tank (Live Sand) and some fish were added. So, I'm about two months along and now I have what looks like what I think are micro bubbles in the tank. I checked the water level in the sump and all is okay. And the water in the sump seems to be clear. I have the PP4's set on the lowest flow setting and I dialed in the flow between the tank and the sump but the bubbles, or at least I think they are still there. They are really tiny and look like snow blowing around, and they don't seem to be blowing out of the return. I don't as yet have a skimmer so ruled that out as a culprit. And as a precaution I added a couple of activated carbon bags in the sump. It's now a week later and no better. Thoughts anyone?
