I second Shao's question, what size tank is that? Looks maybe like a cube?

So... I'm guessing 18x12x20h, which is about what, an 18.7 gallon tall??

is there a standard 20 tall that looks like this? just havin' fun guessin'. :biggrin:

Close, it's actually 24x12x20.

Custom tank with a standard footprint.

I'm using a Mag700 for the return and the whole thing is draining into a 20 gal sump. I might convert the entire sump into a refugium once the money gets a bit looser.

For now, it'll probably run as is until I start getting some coralline coverage on the back.

Thanks for the comments guys
