Iodine is used in the pigmentation process (an iron compound being the main pigment). It is also used in the formation of the calcareous cell wall (Algology, Cellular Plant Biology). It is also suspected to be used in other cellular functions. However it requires a rather small amount so...
Ask your LFS for some sheets of coraline algae that commonly flake off from the sides of coral sales tanks or reef displays. Crush it up and sprinkle it all over the tank. You can also buy some nice coraline encrusted live rock.
As for water chemistry, we need to know the following:
Calcium...
Actually, clown fish are members of the damsel fish group.
Certain groups of damsel fishes are considered anemone fish.
Damsel fish of the genus Dascylis (domino, 3-stripe, 4-stripe, etc.) are anemone fish. How many other genera sold as "damsel fishes" can be considered anemone fish I'm not to...
I have been wanting to offer refractometers at my store.
I have tried to look up Sybon Technologies, but have not been succesful in doing so. I have tried www.sybontech.com like it says in the refractometer instructions, and I have tried searching with yahoo, lycos, and google, but to no avail...
T5 lighting is very intense compared to other bulbs with similar wattage. They make power compact lights look somewhat dim. They run as cool as standard flourescent tubes.
One of my customers is running eight 48inch T5 tubes over a 75 gallon tank and his acros, monti's, zoanthids, shrooms...
Hold up people!
Just like any "maintenance" organism there are pros and cons. we cannot say that an animal is detrimental to all systems as every system is different. Every situation should be viewed on an individual basis. I have seen sand stars cause problems, and I have seen them be problem...
Laminar, not linear. The amount of current needed is dependant on the animals being kept. It is possible to keep low current corals in the same tank as high current ones. You can create "micro environments" within the aquarium just by angling power heads.
My reef circulation is run by an Iwaki...
I would seriously consider having a 20amp breaker or even a dual 20 amp just for the tank. I have 5 power strips going on my reef tank and I was forced to give the tank its own breaker, but backed up by GFCI.
P.S. Try grabbing ahold of the posts of a magnetic start metal halide 400watt...
DITTO!!!
Actually, a hammer and a chisel are what you need.
Score a line where you want the rock to break by lightly hitting the chisel (just like cutting glass), then give the rock a good whack.
In order to help we need to know the specs on your system, any abnormalities in fish behavior the days leading up to the deaths, anyone cleaninging in the house/apartment, arisols, fish hanging near the surface, heavy breathing, etc.
Bryopsis sp., Order Bryopsidaceae[i], Family [i]Caulerpales[b].
This troublesome "macro" algae isn't necessarily fed by phosphates (though it will use it if present). It will also use nitrate, iron, organic phosphate precipitate, and other organic nutrients.
You will need to try different...
If you use a pH meter that can print you out a graph you would notice a decrease in pH durring the dark hours and an increase durring daylight ours.
A pH of 8.1 for a low and 8.3 for a high is just fine.
With the calcium being so low and the dKH so high I want to say that you are using well...
I was going to stay out of this one, but the tension is to much to bare.
I would tend not to say Scolimia as even if it were a damaged/healing specimen the underlying coralite would be extremely cerated, which it does not look like it from the edge of the coral.
Looking at the coral closely and...
