Will my halimeda grow back?

[Jenemone]

When my live rock arrived, it was covered in halimeda, but it all fell off during cycling. I think it is still alive due to tiny new growths (1/8"). It has been two months, so how can I get it to grow back to its original beauty?

Yes it will come back. I ripped nealy all of mine out (I had a lot) and I could just barely make out little stumps. Now, its about 2 weeks later:

It's >2 inches.
Please ignore the micro algae, it's a new tank

One more thing, check your CA level. Try to get it >380 for best growth.

Drewman:

That's gorgeous! I hope mine does that well. Its been about two months since I put the rock in the main tank.

I had the same problem. It took about 4 full months for mine to grow back and now it is going gang busters.

Thank you

Here is a pic I took an hour ago. It's really taken off!

Growing back depends upon whether your alkalinity and calcium levels are up to par.

Alk should be at the very least: 2.8meq/l
Calcium should be at the very least 400ppm

Also it depends if there is enough of it left to grow or if it died out totally.
