Pre Tank Planning/Build

[pet-lover]

Currently I have my 29G standard setup.
Basic rundown = 29G Standard, CPR Aquafuge Medium, Tunze 9004 Skimmer, Vortech MP10, DIY Aquastyle online LED (30 LEDs), inhabitants are follows: breeding true percs, breeding (not so much anymore) yellow tails, Diadem dotty, RBTA, Xenia, Various zoas and of course inverts.


Planning to upgrade to a drilled 65 Gallon Deep sand bed reef setup with a 29G sump.

Aquarium: Aqueon 65 Drilled aquarium with overflow and durso stand pipe attachment.

Im going to be using an ASM G2 Skimmer, refugium and Eheim 1262 pump setup and I would like to ask you guys which sump design would be best:

Design One:


Design Two:


The main question I have is, does design one allow for evaporation to effect chamber 2 and 3, which I would prefer so If the auto top off bucket went dry, or I forget to fill it or whatever reason, it would be less detrimental.


My Planned lighting rig will be two panels of 30 LEDs which would look something like this cooled with a 120mm noctua computer fan:
.

Of course this is just a planning thread, so I am leaving out the obvious equipment like heaters/pumps/other req. equipment.
