Help on brain coral.

leochngyh · 08/02/2006, 11:30 PM

something bad happen on my brain coral.

Tested parameter this morning:
kh = 9
salinity = 1.022 (floating glass)
temp = 27Â¢XC
NH4 = 0
NO2 = 0
NO3 = 20
PO4 = 0
Ca = 480

What can I do to save it??????

Your salinity is low and NO3 is high. and what is "temp = 27Â¢XC"? I would reccomend that you do a 20% water change to bring the NO3 down. Also how old is your tank?

Sal is not to low...they can live at that level...I also do not think it is the N03 either, but I could be wrong. what is your lighting like...it does not look like it can be saved.

I agree with you the salinity isnt enough to do damage neither is the NO3 but it could be the lighting.

my lighting is MH150W.
alrady reposition it to higher site, more lighting. Hope this can help it.
Distance from light to water durface is ~6" and surface to orginal position is ~16". Now move to higher place, from surface is ~6" only.

Temp 27Â¢XC = 80.6Â¢XF. C is Celsius.

Some history, recently (25 July) I have re-setup my tank by changing the sandbed and clean my tank with taken out all the LS.
After finish cleaning, I put back the LR (Soaked in old
SW) and 50% of old water into the tank with just a
thin (< 1") sand bed (crash coral). Everything seem
fine, tested the water parameter for 1 week, no
ammonia and NO2 increase, both showing 0.
This brain coral I purchse on last saturday today I found it is dieing, the skeleton is exposing.
Anyway I can save it?

I would shade it...they do not like alot of light...I would put it on the sand and in a shadow and see how it does.
