Since Lighting, Salt, Parameters, and dosing regimes can play a role in colouration of corals.
Some more info on the two systems;
Both tanks are run with ATI Powermodules with the same mix of Daylight, Blue Plus and Actinic over the tanks.
Both thanks use Royal Nature Salt.
Both thanks maintain a constant salinity of 1.025 with the aid of Tunze Osmolators.
Both tanks run the Fauna Marin Balling System with parameters of;
Calcium - 400-420
Alkalinity - 8.2-8.5
Magnesium - 1350
Both Systems maintain a Redox of - 400-425
Both systems run Fauna Marin CarbL and Ultra Power Phos.
Differences in the two systems;
System 1, with the brighter Pink Birds Nest, doses Ultra Organic manually daily.
System 1 is 500g and System 2 is 800g.
System 1 runs and MR-6 and System 2 runs an ORCA Pro II.
Both tanks have the same overall flow, but System 1 uses a closed loop with a hammer head and System 2 uses a combination of MP10's, Tunzes and Koralias to achieve the same flow rate.
Specifically, we have found that Ultra Organic has had by far the most noticable effect on our corals that were pink aka birdnest, pocillopora and stylos.
This is in no way a perfect test, but it's pretty close.
