What's wrong?

[VickyH]

Why are my mushies getting smaller and losing colour, some seem to have disappeared altogether also my candy nane seems to be suffering. All other corals looking really good, I laso have 2 leathers, a torch coral, hammer coral, bush coral and 1 other I've forgotten the name of but begins with T!
I have an arcadia luminaire with 1 blue actinic and 3 white tubes and on last set of tests water params were good.

Definitely looks like some bleaching. Could be some chemical warfare, what are your water parameters though? I'm not familiar with that lighting fixtuer either...what kind is it?

 

[BeelzeBob]

second one down is a skeleton.

ive seen mushies do that @ the LFS under 500w MH's.

How bigs the tank, and what type and pwer are dem lights?


just at first glance, have you tried movin them around? oo oo are they new?

 

[VickyH]

They are not new and have been in that spot since I bought them months ago, only recent change has been the lighting. It's one of those luminaires that stand over the tank resting on the glass at each end. The 3 white tubes are marine white 14000k, not sure about blue just know it's actinic. Last water tests came back ok but will do more tomorrow.

 

[VickyH]

Do you mean second picture down? That's the candy cane, not a good picture but still a very bright green in the middle

 

[BeelzeBob]

thats um, dead.

you can see its entire skeleton.

14000k is the SPECTRUM, how big is your tank and whats the wattage of your light?

 

[VickyH]

tank is 4ft x 15" x 18" deep, and they are 54w tubes

 

[Reefscape]

If possible, i would move them to the bottom of the tank, maybe it was due to not acclimatizing the tank to the new light perhaps..Certainly suffering from bleaching..

Water params are as follows -
Ammonia 0
Nitrite 0
Nitrate 20 ??
pH 7.8 - having trouble with this isn't it a bit low?
kH 110mg/l
salinity 0.024
temp 24
phos
0
calcium 460mg/l
iron 0
strontium 4
did a full set of tests today except for iodine, I have salifert test and I tested for iodide but it came back as 0- ??

I'm guessing the alk reading is actually ppm, and it is out of balance with your Ca.
