thanks guys.

I took the pictures, cause the bubble was getting too large.
It has now moved onto a bigger home.
There a hole in my tank, and in my heart, it was the first coral I bought. :(

There's a tomato and a false clown in there. Hiding is the firefish, bi-colour dotty, CBS, and cleaner.
Yup it a squammy in there.
You know,.... fuzzy sticks just don't do it for me. I am LPS man.

The tank is a 47g bow. I am running a 96w actinic, 96w 10k, 2x55w50/50.
I need to replace the 50/50 with 10k, or at least 1.
It has a 25~30g custom sump/fuge.
Modified Prizm, that works great.

Other than the 1 sump return in the top left corner, I've just added a powerhead under the hang on overflow in the top right corner.
