As the topic says I have a golf-ball coral and anenome decline, however not on all of them. In fact I have a frogspawn coral which is going great guns, and another anenome (with a fluro pink stem) that is going okay as well (see side note below about this).
My levels are:
Nitrate: < 5 (very slight pink colour)
: 390 (i have buffered this and will test daily until 450)
: 130 (i have buffered tihs and will test daily until 200)
: Untested this week, but is generally at 8.3
The golfball sort of comes out, but then will sometimes quickly go away. The baby anenomes in the rock have been closed for some times now (maybe a week).
The only thing I can see other than the low CA
above is that the lights are almost 12 months old (white one), and 6 months (blue one).
Any tips on what might be causing this problem? I have done two water changes, two weeks apart of around 50L. I provide liquid coral and anenome feed every second day.
The tank capacity is 180L with around 45KG of rock. The tank has been running nicely for about 12 months. I have as fish: 2 oscellaris clowsn, 2 fire gobys, 1 annularis angel, 1 red blenny and an orange star fish.
I changed the pre-filter pad about 3 weeks ago, and haven't had activated carbon in there for a while.. when I did have activated carbon in there it seemed like the tank went much better than it has without it.
Any tips would be great.
