I usually don't post but I do a lot of reading.
This time I have a problem that doesnt seem to be going away and my local Big Als doesn't seem to be able to help me find out the cause.
Over the last couple of weeks some of my corals have been dying off. First it was my tourch. I have had it for about 9 months. A couple days before it died, it seemed fine, then it turned to mush and eventually I had to remove it because it was making a mess of my tank. It took about 48 hours to completely go from good to bad.
At the same time my pink xiena (excuse my spelling) started to get smaller and smaller. By weeks end, it was gone. The funny thing is that I have two other pink xeina's (much smaller) that are from the same colony that are doing well as far as I can tell.
Also, I have a devils claw that used to be full and I could see its small purple polyps but not anymore. Its shrivilled and I dont see the small polyps come out anymore.
The latest thing I have noticed is that my disc coral which usually has small tentacles come out at night has stopped coming out and I can see it starting to lose its color and turn white and brown.
I dont know if this will help with the diagnosis but I have noticed two other things about the tank that are unusual. I used to have to clean out the overflow once a week, but lately, its been staying clean and I do not have the usual growth I once did.
Also, I have this green algae that micro brittle stars live in. I used to have a lot of it and now its been dissappearing. I still have a few clumps but its mostly gone.
My other corals, fish and inverts are doing well.
I have a mushroom shaped leather, a green and brown goniopora, sun corals, grass looking coral, brown zoos and others. I even have a clam which I was told would only survive with excellent water conditions and its doing well.
Here is a list of what I have checked;
Salinity, 1.24
PH, nitrites, nitrates, amonia and calcium.
All of these are looking great according to my test kits, except the calcium was a little low. I just started mixing in calcium buffer to fix this.
I am doing water changes once a week. I have a 72 gallon tank and change about 8-9 gallons each week.
The only things I can think of now are;
1. I stopped using essential nutrients about a month ago because I ran out. I just got some more and began using it again.
2. My lights are Current USA Nova Pro t5 lights and maybe my bulbs need to be replaced? I have had the unit for about 10 months and most of the bulbs are factory. The lights look bright, but I know better than to trust my eyes when it comes to this hobby.
I was looking to see what all my failing corals have in common so I can find a common denominator and solve my problem but I dont know enough about my corals to know what the dying ones all have in common.
Any advice would be much appreciated. I feel bad losing corals, fish or anything for that matter. I need to stop the bleeding but I need help to figure this one out.
Thank you,
