Red Dragon Acropora

[Restless10101]

Hey all.

I have a piece of Red Dragon Acro that keeps losing it colour. I have had it for about 5 months, it is growing, but just seems to be very light in colour. It is currently sitting about 27 inches below the T5's but it has been moved around a couple times. First in was 12 inches below the T5's then about a month later it was moved down about 8 inches. 2 months later I moved it down to where it currently is.

Aquarium (running for approximately 10 months):

90 gallon with 20 gallon sump.
6, 54w T5 bulbs (ATI bulbs)
SWC 160 skimmer, with light bio load
BRS single media reactor running with Seachem PhosGaurd

Just stopped using C Balance two part additive and switched to a calcium reactor, but colour was bad before the switch.


Water Parameters:
Salinity : 1.025
PH: 7.9 - 8.1
Alk : 7
Calcium : 440
Nitrates : undetectable
Phosphates : undetectable
Mag : ?

I was feeding my corals with Coral Frenzy and Koral Color (brightwells) every third day, but have stopped doing so in the last month. Again they colour was fading even when feeding my corals.



Any help would be greatly appreciated.

Thanks!
