brighter colors on corals?

kurcoba · 05/16/2009, 10:19 PM

Does somebody know what additives are good for making the colors brighter on corals?
For some reason the color of the corals in my tank are not as bright as they were when I just bought them. for example the nuclear green zoas they have a dark green color and the same happens to the other zoas in the tank their color is not too bright as they were.
Some mushrooms are bleached a little bit, and some other LPS are OK.
I upgraded my lights recently (1 1/2 month ago) from fluorescent (200w)
to MH (2-150w 14000 K 2-65w actinic) I m running a chiller to keep tempeture on 79f
I just checked levels twice (using a different testing method ) and the results are good.
What can be the problem?
Is there an additive I can use to make their color brighter? or they are just adjusting to the light?
Thanks

"Results are good" tells us absolutely nothing about your tank. Sorry.

Alk level and test kit?
Phosphate level and test kit?
Water source?
Salt brand?
Salinity?

you probably shocked your corals by jumping to such an intense light source in comparison. they may stay that color or come back good way to tell will be if they bud off or die off.

+1. Also what temp. lighting did you used to have on the Flouro bulbs??

Are you having fluctuations in temp (between day and night shift) or is the chiller keeping it constant?

Phosphate level: less than 0.1(instant ocean test/Test Lab)
water source:R/O water
I use Oceanic
Salinity Grade: 1.022
Chiller keeps Temp. between 79f and 80f
What should be the right Alk level?
Ca level: 400(test Lab)
Any recommendations about what's the best inexpensive test kit?
What brand of salt has worked for you guys better?

Your salinity should be at 1.025/6

Alk should be around 9

Todd is right. Be sure you are using a calibrated refractometer to measure SG (salinity)
