NICE!

Hey guys just wanted to get your thoughts on this, looking at getting the custom sump started and it will prob be around 100g, What would you guys put in it for this type of tank?

-live rock chamber?
-Refugium?
-Any custom stuff i should look into?

I think a better question is, what do you want in your sump ? :biggrin:

A live rock chamber is nice to have, but not necessary in a sump. A refugium is nice to have but not necessary.

I would say, if someone is considering a 500G system, the cost is not an issue.

Size really depends on what you want to accomplish.

If I had space and the means to support a 500G tank..... Heck!

BUT as mentioned.... exponentially more for everything. From salt to lighting to rock and sand... coral and fish. You will have an empty 500G tank with 3 frags and a blenny, if you know what I mean.

Be sure to start a build. :wink:
