"Dr MACs" is actually called Pacific East Aquaculture. They are on the Eastern Shore about 2 hours from DC. I go there all the time. Dr Mac, the owner, travels to Jakarta to hand pick corals plus they grow a lot in his indoor coral farm. I have ordered from them and then picked up at the club meetings.

Yes, its a lobo. Do Lobos have sweepers?

I've done several tank upgrades sand has a lot of beneficial bacteria in it as does the rock. I've heard the water itself has little.

The shroom is gone and there is a slime on the rock where it is. There are really no sweeper near it and I know I did not touch it.

Mushroom encased in strange jelly like, translucent mass. Yesterday it was perfectly healthy and looked the same as the red shroom above

Don't know but when in doubt kill it with fire

I've solved more than one algae problem by ensuring variety in my CUC. Battled one kind of algae for a year until I added a more diverse CUC and it was gone in less than a week. Hermits eat GHA. Also, I had a lot of luck doing successive 3 day black outs followed by 50% water changes. I measured 'trates before, during and after post-blackout water change and clearly I removed half the 'trates that sustained the algae. I made sure the tank was completely dark. For a 50% change you probably want to match temp and salinity more precisely. And this whole discussion assumes you have eliminated the source of your trates.

Matching precise PAR to specific corals is probably a waste of time but completely ignoring it, I think, is also a mistake. Ignore PAR then put acropora under PAR 30 and a funghia under PAR 300. (Don't do that!)

Right, but the idea is that the new corals would be more hardy

WHAT CHANGED BEFORE BLEACHING? When I see corals in trouble and assuming there were no obvious changes, I just go ahead and do a 40-45% water change? Half the time this solves problem.

Those mandarins are nice. Unless trained to eat frozen they tend to only eat things that move. I've seen them eat bristleworms. Also, blood-worms when I make them jiggle with a baster. I also had success getting the eat orange and red sushi roe. My MD died from ich which is unusual but it does happen.

What ever it is, I would siphon it out immediately

Dumb question: you microwaved the water before you put the fish in? TSA did not open the bag?! They could easily have told you that you can't bring liquid thru security.

Had a BC29. scraped paint off back and just used a florescent bulb. Submersible broke.

Interesting. On the small scale that we use carbon in our tanks, its cheap enough that we can change it out frequently. I have heard stories of people removing some media (like bioballs) holding beneficial bacteria and then a cycle ensuing but I don't use enough carbon for that to be a problem.

If you took a coral from one tank and put it another tank with exactly the same PAR but a differently programmed spectrum, say less purple and more blue in the new tank, could it still shock the coral? Or is proper light acclimation of a coral entirely dependent on PAR?

Holy cow! Started my greens out under 30 par. I guess I can move them up higher.

I've read Trumpets need "moderate" lighting but moderate doesn't say much. Can anyone tell me what PAR they have green Caulastrea? I have my brown/blue Caulastrea under very high lighting and they are fine.

"... some of us smell better than fish."

Many people farther north were wondering why it didn't get darker. I saw the "totality" and even the tiniest sliver of the sun can produce enough light to make it seem like "day time". Take your tank light outside on a bright summer day and hold it over the pavement. There is no comparison to the sun. Once the sun was totally eclipsed it got dark like night very fast --in a matter of seconds.

Drove 20 hours to south carolina and back, battled returning traffic jams just to see the 2.5 minute totality --worth every second of it. I've seen the Pyramids, of Egypt, Himalayas, active volcanoes, Eiffel Tower, etc. The totality was one of the top 10 most incredible things I've ever seen. Saw stars in the sky, a bat flew over but the coolest part was looking up at the total eclipse --Indescribable. Tried to make a video but was just overwhelmed.

I took my carbon out a week ago and now I have a slime slick on the surface.

Excellent info.
