Duncan Corals - Still having trouble !

hey everyone , i mentioned in a previous post that i was struggling with my duncans . now iv recently tried target feeding and repositioning them over the past 2 weeks , and still there isnt much difference . maybe 1 or 2 might have come out a bit more than the others , can anyone shed some light into where im going wrong? iv tried so many things , all parameteres are pefect as well as calcium and im at ends wit .

tank is a 35cm2 cube. r

any help would be great

 

Duncans are low light, deep water corals. Try changing the bulb to blue light.

 

hi nathan
judging by reflection on water it seems to be either twin t5 lighting or a single PC lamp

also the water surface seems very calm to me, so I feel that either light or flow are the key issues here , if your certain your parameter tests are all in order

they could of been stung by that torch you have in there. thats what it looks like. or maybe a parasite. and they could be very stressed out.

 

there are 4 bulbs in the light , but they are 2 joined together , 1 is blue and 1 is white , do you recomend putting another blue in do u ?

and for flow would you recommend it be a stronger flow?... the store where i purchase have the exact same setup and they're tank is pretty stagnent

 

the torch was only put in 2 days ago , i doubt its anything to do with that , as they have been like this for a while...

 

Yes and Yes
Try for at least 10x flow

 

Maybe start by having your return bar in the water pointing to the front of the tank. And buy a small circulation pump.

 

what is your magnesium level at? All my corals have perked up since Ive been keeping my magnesium up and my kh.Ive been alot more thorough in my tests and its paid off.

 

I check weekly
magnesium
kh
ph
calcium
nitrates
nitrites
salinity
I dose strontium and iodide and potassium in very small amounts.
Duncans should do well under most lighting ie...pcs,t5s
