Calerpa trouble!!

[mattyb327]

OK, maybe not the right forum, but not sure. I'm sure i'll get corrected. Anyway, I put some calerpa in my seahorse tank about three weeks ago. It seems to have taken over the tank and turned the tank green. There are no seahorse in the tank yet just a little goby it think i need to take out of there. How do i resolve the green tank issue? Water changes? Any input would be helpful.....

If you say it is taking over the tank trim it out. Harvesting caulerpa acts as a nutrient export path - this is what you want. To reduce the coloration of the water, use water changes.
