New tank design graphic ... Tell me what you think...

[Zylumn]

Good job a lot of thought has gone into this so far.
I hope you don't mind a few suggestions.

- I liked the idea of 1 overflow feeding directly to the refugium. Why run another pump when you really don't have to. (you would need then ball/gate valves on your lines)
- Your return pump would essentially be in a chamber of about 3 or so gallons of water. ( If you don't mind topping up every day it should be no problem, but you will have to keep a close eye on your water level) I would make area (L) just large enough to house your skimmer and make your return area as large as you can; possibly switching dimensions. This will give you a few days before a top up.

- Also your bulkhead (I) should be below or equal to the hight of your baffle between (F) and (G)
