A skimmer and Surface Skimming will keep it away. It also causes a lower PH because of the reduced gas exchange with a film of DOCs on the surface.

I believe 14ppt is the correct salinity when using a refractometer.

LOL! Good luck with the Chiton. I think they're wonderful and very interesting. Oh, it's now Dr. Bang :D

They have a long planktonic stage so it's unlikely that the larvae would survive long enough to settle. I have to ask - how did you come up with that member name? It doesn't sound very polite if you ask me... :lol:

Can you give a more detailed description? My first thought is still a type of Whelk, perhaps one of the Nassarius species.

It's probably some type of Whelk. Most are carnivores but some are beneficial.

It's a harmless/beneficial Fireworm. I'd keep it.

Probably Sponges that have built up in your plumbing. When the water stops they expand pretty quickly and then when the water gets going again the current tears them apart. Harmless stuff.

I also recommend installing with the nipple up. Mercury will collect there if it's pointed down and lower the lifespan of the bulb.

I don't have a lot of experience with it because my Pencil-Streaked Rabbitfish ate mine really quickly. I do not believe it spreads fast.

It's a type of micro algae. I can't remember what it's called. Similar to Mermaids hair.

I thought they already were being protected.

In my opinion a Six-Line will out-compete the Dragonette for food and the Dragonette will wilt away over the next six months.

Yes. Lionfish will eat Goldfish is a good example. Most fish will go nuts over red Brine Shrimp even though they are devoid of nutrition.

I suppose it depends on your definition of "Reef Safe". I've had large ones eat Peppermint Shrimp and attempt to catch fish. I've never seen one harm a coral though.

The only type of crabs I have found to be reef safe are Porcelain and Acropora Crabs.

Just average.

Eggs are typically a little hardier than other types of frozen foods. I think they're probably fine but the sniff test is a really good idea.

It's definately an Aiptasia.

I suppose I'm wrong. I thought Acetate was a salt but I'm no chemist, not by a long shot. I can't see any possible way for algae to use it though. Is it indirect? How do carbohydrates feed algae? When I experimented with it the algae quickly died off. Has your experience been different?

The toxin is called Caulerpin. It doesn't promote algae growth that I know of. It is poisonous to animals though including coral & fish. Carbon removes it just about instantly.

I've experimented quite a bit with limewater and vinegar. My experience has been the opposite. I've found that if you skim heavily then vinegar will decrease algae. Experiences differ though. The vinegar I use doesn't have any sugar so perhaps that's the difference. I just get the cheap...
