I have a new Duncan frag that spends a lot of time closed. It opens out once or twice each day, sometimes for a couple of hours, but often only half extended.
The frag has two heads, and each head is in the process of splitting. One has three 'buds', the other has just one larger one. Is this the reason it isn't extending fully?
In case it helps, other corals in the tank - sinularia, green star pol;yps, leptastrea and acans, all seem to extend normally.
Approx. parameters are (using a test strip - results marked with ** are very hard to read)
- pH 8.2 (could be +/- 0.2)
- nitrate 20 mg/l
- nitrite 0
- GH 150+ **
- TA 100 mg/l **
- KH 150 mg/l **
- chlorine/iron/copper all zero
Using natural seawater, not adding anything, but water changes weekly of about 15%
