receding hammer coral

[kelso1980]

My hammer coral seems to be slowly receding from the base. It looks good, it's never closed up, it has good coloring and everything. I don't do well with hard corals :rolleye1: softies do really well though, zoos are happy, but nothing seems to grow. The zoos generally stay the same. I dont see growth, but they're not dying either. I dose alk/cal but nothing else. Should I be dosing mag? it's a 12 G aquapod. Anyone have any ideas?

What are your water parameters???

How long are the lights on for? Do you supplement their feeding? How old are the bulbs?

Just got my water tested. said everything looks great. they did not test magnesium though. Bulbs are only 3 months old. I add phytoplex to the tank occasionally but that's all the supplemental feeding I do. I dont have my own water test kit (that's probably the next thing I do) but is it enough if the aquarium place says my water is in check? the blues are on for 12 hrs and whites on for 10. that too much?

where is your hammer coral placed at??

 

[kelso1980]

about middle of the tank and what I think is just the right amount of current.

current is proably not the issue. I would place it on the bottom or low. Hammer is normally a branching coral which means that when the branch get's too heavy it will brake off and land on the sea floor. So they are use to the low light. You can also try to feed it baby brine, or even small mysis. That will help it too. Any pictures??
