The big fridge comes from my partner Leanne’s nick name for our prop room a 15 x 15m shed made of cool room material. We decided on the construction for energy effiecy of heating and cooling.
We are on a pretty steep learning curve getting it all together part the reason for the TJ I am sure many of the enthusiasts here may set us on the right track when we stray
also we would like to see more coral prop in Aus so hopefully we can help with some info along the way. 
System Objectives:
Our objective is to supply an environmentally friendly alternative to wild collect corals and make some of the more rarely collected corals more readily available.
System Type:
So far we have a Q system, a brood stock / larva rearing system for fish a coral brood / grow out system and a experimental 200ltr DIY synthetic sea water / cultured specimen display tank.
Display System:
Strike up Date:
The room went up early 2010
Specifications:
To date : Q system 2500ltrs, fish 2000ish ltrs, coral grow system 1 6000ltrs and display 200ltrs
Lighting: LED on all the coral with some T5HO on the fish for the anemones.
Stand: Stand specifications.
Support systems:
System Water: Natural salt water for coral and brood stock, DIY artificial salt water on the display
Water circulation: In tank water circulation on the Q system is surge buckets. Coral system 1 use Tunzie stream pumps.
Return Pump: Return via Performance pro pumps as they are very energy effiecient for the job
Skimmer: Tunzie, various on the systems but stoked with the 6080 on the coral system
Evaporation Top Up:
Top off via timed pumps
water changes:
Auto water changes via timed pumps to waste and float valves to bring NSW in.
Chemical Support:
GHL dosing units adding Calcium, KH, Mg and Iodine also adding Brightwell 'koral color' to the coral system.
Current Water Chemistry:
Nitrates: 1ppm
Phosphates: 0.07
Alkalinity: 9DKH
Calcium: 420ppm
Salinity / Specific Gravity: 1026
Magnesuim: 1300
