Will pray for his soul.  Us squares won't go within 100 miles of that place, without a shotgun of course. ;D

 

Jason, How's the coral looking now?

Interesting quotes from the article Matt linked:

...two articles support the observation, Delbeek's personal observation, that good water flow is an essential component in a successful reef aquarium that houses a lot SPS corals such as Acropora and may help to prevent coral bleaching brought on by increased water temperatures and light levels."

"may represent corals with a strain of zooxanthellae better adapted to high temperatures."

The tests with varying flows do indicate that higher flows seem to offset the bleaching associated with higher temps.

 

No real Change John. Haven't seen a polyp in weeks and now the algae is taking over. I placed it in high flow about 5 days ago.

Still undecided on what I'm going to do.

Jason,

My SPS knowledge is just about nil, that's why I am asking

Are you able to to view where the polyps should be up close, like with a magnifying glass?

John

 

High flow seems to be more effective before bleaching according to the article, do you concur Jason/John?

 

I have no experience in Acro etc Craig so wont comment.  I do have a question though, what are the visual differences between a piece of Acro that is experiencing RTN and Bleaching?  In other words is there an immediate visual clue that can determine which one it is?

While I am at it, I assume that bleaching is sometimes recoverable, is that also true of RTN?  

And lastly, what causes RTN.

See that guys  3 questions all in one post

John,

Did you get a chance to review the article Matt linked?

 

OK it hasn't lost any tissue. I know this for sure.
It is a Walt-smith wild tri colour. I purchased it from a coral farm here in Vancouver and the staff there deal mainly in SPS.
I know wild colonies are very susceptible to bleaching when aggravated. Flow has always been high. But a nastily crab migrated to the colony about a 2 months ago. It took me almost two months to get it off. My temp went through the roof in lats June. Evenings here are cool but day time temps were between 30 and 36 every day. This cause the tank temp to go as high as 86 during the day. The Temp would return to 80-81 at night. I think this is were my problems are. The temp swing was too great. Everything else in the tank is fine.

I'll keep you up dated

Farging crabs.
J, I'd be curious to know what the coral farm suggests you do. You should call them. Wouldn't hurt.
