Hi! My name is Sam and I have been keeping reef tanks for about 12 years or so. Last November I started breeding GSM clowns - something I'd been researching for years and always wanted to try. I found the main issue I had was space for grow-out of the juveniles (as they are quite territorial). The larval and meta phases were easy by comparison, but once they were about 4-5 weeks old they would begin madly killing/eating each other. At that time, my grow-out system was a 2ft tank. So after a year of planning, I am building a purpose-built grow-out system in my backyard contained within an air conditioned (and heavily insulated!) shed. This way I can hopefully produce larger batches of GSM and Darwin clowns, and maybe try some other species down the track. I should mention that this is 99% a labour of love, and if it makes any profit that's a bonus - but not my primary focus!
I would love to hear any advice, equipment tips etc that folks have to offer! 
System Objectives: A scaled-down version of a commercial hatchery set-up. Inspired by pics such as this:
System Type: Fish-only Grow-out system, with biological and chemical filtration.
Display System:
Strike up Date: December 2013 - January 2014.
Shed: Colorbond Shed - 3.8m (L) X 2.2m (W) X 2.4 (H). Due for delivery 6th December! Has 2 x skylight panels (over proposed aquaculture tank sites). Rest of roof and walls will be insulated by my Dad and myself after install.
Display Tank: Duraplas 1000L Aquaculture Tank - 1 initially, but room for a second if needed. Due for delivery 16th December! Pics as below:
Display Lighting: Natural sunlight (skylights) + 2 x Aqualina Slimline LED 36" lights.
Stand: Comes with Tank.
Sump: Still deciding between a glass or plastic sump. Will house skimmer, live rock and other media.
Refugium: Not sure if will add a DSB or not - will grow some macro algae somewhere though...
Refugium Lighting: Natural sunlight + LED.
Support systems:
System Water: Natural salt water on start up. Planning to recycle water changes to save water as follows: Display -> grow-out -> plankton systems -> discard.
Display Water circulation: Central riser pipe type overflow.
Return Pump: Tunze Silence Pro.
Skimmer: Bubble Magus BM-NAC220-CS Cone Protein Skimmer.
Evaporation Top Up:Auto top up with RODI.
Any advice/comments are much appreciated! Looking forward to having all my aquaculture activities neatly tucked away and out of the house!
what sort of money are you looking at for your skimmer? You could probably get a better alternative than the Skimz for similar dollars IMO.
Because I am currently renting, we have used a sleeper frame and pavers instead of a slab (which would have been MUCH easier!). Anyway, here it is being Lab tested:
