Porites Problem

Hurley675 · #1 08/22/2007, 03:07 PM

Hey
I have recently purchased a Porites Cydrilica( I think thats how you spell it) When I bought it and put it in my tank it was doing great all polyps exteted for about a week than I ended up moving the piece to a higher location(about 5" up) but the water movement was lower. After about 2 days the polyps were retratected and the Porites had a wierd film on it that was all shiny. In the end I decided to put it back to the original spot and most of the film is off but the polyps are still not extented. Is there anything that I can do.

here are water specs:
Nitrate:0
Nitrite:0
Ammonia:0
Phospahte:0
PH:8.3
Alk:8.1
Calcium:415

Anything can help

-Thanks

Always been my fav coral. Recently lost an old colony secondary to temp spike.

Yes they r finiki unfortunately

My porites does the same ever since I've had it. Every few weeks it gets a film then sheds it off. Kinda like a leather does. I think it's normal. Higher flow is much better to remove the film, otherwise it'll get algae'd. I have mine high up in the tank.

Increase water flow. Porites "shed".

Increase water flow, but not aimed directly at the coral or
you can cause dead spots.

Porities cylindrical does need a lot of flow. Most are found on the reef crest....

My cylindrica does occasionally seem to shed a layer of skin. I would disagree about it being finicky though - I bought a medium sized piece of LR and put it in my tank during the cycle, and a few days later little polyps started appearing all over the thing. Turned out that the whole rock was actually a porites cylindrica that had made it through transportation, storage in a LR curing bin at my LFS and the cycle, and it must have been without light or decent flow for a week or two during all this.

I would caution everyone that there are many species of Porites and species are easily confused. Some species are apparently more "hardy" than others but it seems that all species appreciate excellent water movement.
To put it in simpler language, it's very possible that the corals being discussed here are not P. cylindrica but a similar looking species.
