I didn't want to be the guy starting yet another skimmer thread! But here goes nothin. I'll get the the tape measure out another day. Lets assume that I can make room. I'm more concerned with what brands and models are recommended. I'll modify the baffles or sumps if needed.
120 gallon DT with roughly 30 gallons in sump/fuge.
1 Brazilian Golden Moray
1 White Ribbon Eel,
1 Skeletor Eel.
1 dampiera pseudochromis. Will be removing the dampiera and adding maybe 2 yellow tangs or similar.
I run the huge bag of CHemipure elite, purigen, 10 mangroves, and gobs of Macro algae.
I need something really good in this tank. So lets talk quality and what would be best instead of money..However!! I will not spend a grand on a bubbleking!
And...
40 gallon mixed reef in the works with 30 g sump/fuge.
lots of "Nano" tankmates. Here is my planned list
1 Yellow Assessor
2 Borbonius Anthias
A couple Blennies
several Pom Pom crabs
Several Skunk Shrimp
assorted corals
etc, Lets just call it medium bioload
Something good. I'd like perfect water quality here so I can indulge in those impulse coral buys

<$400. I was thinking of maybe an SWC extreme 120.
Both need to be in the sump.
