This appears to be "orange coralline". The other pics look like sponges. Although the orange coralline some people seem to think is just dying red...
I've never heard of a watchman goby eating a coral. They don't have teeth for one. Lots of things eat dead and dying stuff though :P
That's not actually entirely true you know? It's true of colored LEDs. White LEDs usually use blue to excite a phosphor, actually, typically the...
Instant change or slow change? Usually LPS corals can't "change" pigmentation like some SPS can. They can produce more or less fluorescent pigment...
Okay, opportunistic infection due to lack of light/food :) It doesn't really make sense that it is being eaten if there are lots of other LPS in the...
It sounds like most likely it wasn't getting enough light. Did you take a PAR reading? My understanding is corals can take a long time to waste...
Lots of ideas, but not nearl y enough info to really make any guesses. It is not difficult at all to raise calcium, if you add a certain amount, it...
Not just because algae is absorbing. It can also be in organic form, which doesn't show up on tests, algae can't utilize and cyano can utilize....
I don't go that far, but I just siphon old water out turn on a pump to discharge and turn on another pump to add new water in until at the right...
Corals don't neccesarily care, they may initially do best with similar spectrum to whatever you have, but shoulmadjust.. What "look" do you like?
Well, that's a letdown, I thought Taylor was on the site now :P Oh well, happy birthday all!
Skimmers are not very efficient on small tanks, there just isn't enough water volume/organics to keep a constant foam head. To make it really work...
Thanks, I will take a look at the link. Water changes do not provide the necessary ca and alk, but they do provide the set-point. If my setpoint is...
PE is primarily a feeding response, but corals will retract to protect against predators. So, mostly likely the coral does not sense any food, or...
Tank you for the article. Your recommended salinitity levels seems way low though. Most references reference an average of about 35ppt. For...
Ouch, clams probably aren't to sensitive to stings, but sure don't want those spreading.
I have played with refugiums and find they seem to cause more issues than they solve. I was fugeless for years and added one for about a year ago...
Not really enough info. I'm not aware of a disease that would cause tearing, but possible. If not, more likely something nipping at it. If it was...
I have a few, they are good. Coral Reefs November 2006, Volume 25, Issue 4, pp 609-615 Symbiotic crabs maintain coral health by clearing sediments...
Good idea. Remember basic reef chemistry and what happens when you combine calcium and bicarbonate (I.e. alkalinity). Same thing that happens if...
