open brain coral

[nyfisherman]

I recently bought a open brain coral (Trachyphyllia). The coral was under VHO in the store and I have two tanks one with MH and the other with PC's. The store said I could put it under MH but it hasn,t expanded yet. That was two days ago, the book I have is pretty vague on Lighting and current with this specific coral. What has worked best for those that have it?

 

[nyfisherman]

Is it also ok to set them on the substrate (sand)?

 

[bigarn]

You have it under MH lighting correct? If so, it has to acclimate to them ... IME they do best on the sandbed with low to moderate flow.

 

[nyfisherman]

Yeah I put it under a 10000k 250w MH. I think I have to much current on it.

Mine liked LOW flow.

 

[nyfisherman]

here it is looks more like a closed brain.

If that's CC it could be irritateing it.

Not familar- crushed coral? it is 100% agronite and some crushed shell mix brought back from a trip to FL

 

[shnabbles]

looks like more crushed shell mix then sand

 

[jacknjill]

yeah, looks like the crushed shells was a mistake, they look sharp for the brain

How deep is your tank? In my experiance they really dont like a lot light... If it doesn't start to look better where youve got it try moving it to a partially shaded spot.

It still hasn't opened, so I put it in my 55g under 2x96w pc & a 40w actinic. Lower flow and no shell mix. We'll see what happens. The other tank it a 20-25g tall with a 250w MH it's 22" tall with 5" sand bed made of smaller than sugar sized agronite and mixed with some cool broken shells (lots of pinks and purples) that I got off a beach in FL. I got a 5gallon bucket full, and it was free.
