Hi guys
Over the last few months something very strange has been happening in my tank.
It started off with one or two corals getting sick and not recovering. More recently single corals will start to die, or even a single head (like my torch) but the rest of the coral, or neihgbouring corals of similar species remain healthy.
Here are my parameters:
pH: 8.2
kH: 8
Mag: 1300
Cal: 420
Salinity: 1.026
I use Seachem Reefsalt, 15% WC once a month.
Filtration:
18cm DSB with chaeto and algae scrubber above.
TS2 skimmer.
500ml biocubes
Dosing:
Seachem Aquavitro Range - 8.4, Calcium and Ions, with Fuel added every now and then.
Lighting: 54* cree 3W LEDs, DIY
Livestock:
Regal Tang
Sailfin Tang
Clownfish
Mandarin
Lionfish
Cleaner Wrasse
Black Tang (don't know proper name, the common one caught in Natal)
Coral banded shrimp
Ok, the hard part - here is the list of corals that have gotten sick or died in the last few months:
Red plating monti
Green plating monti - the red went first, literally died over the space of 2 days. The green went about a month later. Both corals had started off the size of a R5 coin and grown to about the size of a side plate. The weird thing is, with the green monti I had bumped it once and broken a few pieces off, so I put them elsewhere in the tank. These frags are still doing fine! ???Had these for more than 3 years, really sad to lose them.
Trumpet coral - had it for 2 years, one day all the heads remained retracted. A week later it was dead.
Open brain
Hammer coral
Moon coral
Various mushrooms
Here's a full tank shot (the green monti is still fine here, the red had just died):
This pic I took this morning - I've had this brain for about 18 months and it has thrived - until now. You can see the dead moon coral behind, and the dead green monti to the right.
With each coral, the same process happens - it closes up and slowly fades away. Very disheartening!
Sorry for the long post, I thought it best to post as much info as possible.
I'm at a loss. Do I have some bacteria? Or perhaps something that comes out at night and munches on corals?
Any help, ideas or insight, please!
Cheers
Dan
