I saw two baby brittle stars (looked green) last night. They are VERY small, 2 cm legs and all with a body of about 2 mm. Any chance they will grow up or are they for the most part just food? Thanks, Sundance

So how do I tell if my clam is happy and getting everything it need. Someone said if it's wide open it's not happy. I haven't seen a clam yet when left alone for a while in good light that didn't open up wide. Sundance

Not your specific problem but I am having yellow polyps disappear and the only thing I have seen near them other than a snail is one my emerald crabs, the same one a number of times.

I have MH and VHO lights now on my 80g, I was just experimenting with the Florescent floods light. With one end of my 80g tank lit with the florescent flood and the other with my MH you can see that the flood is about 2/3 the intensity of the MH, but not bad when you compare HUNDREDS of dollars...

Your tank looks GREAT. The reason I'm asking is Home Depot had 500W fluorescent flood lights. I realize that the light output is not going to be as high as a 500w MH But if I can get rid of all that heat and if a 500w is even close to the out put of my 250W MH it might be worth it to give this a...

What is the reason for the 10,000k lights for a reef tank? Is there any reason 6700k daylight will not do the job?

Do I need a protein skimmer on my 20g hospital/quarantine tank. It has one small fish, a brittle star and a anemone in there right now. If yes what is a cheap one that will do the job? Thanks, Sundance

Last but not least is this a pod, I'll try to get a better picture. I have them all over the bottom, if they are bad I'm in trouble.

Is this a slug or snail, good or bad?

Here are three images of things that I have just seen. Can you ID them and let me know if I should try to get rid of them? The last image is not to clear, is this a "pod"? Thanks

What was the camera you used?

Do Emerald crabs eat coral. I am having coral disappear. A few days ago I noticed my Yellow polyps disappearing. Today I found a coral branch that had two Ricordea buttons on it and they are all but gone. The only thing I have seen near them is Turbo snails and Emerald crabs. I have one emerald...

A friend said he just read that you could elevate your ph 8.6 to 8.9 to induce and stimulate coralline algae growth. Has anyone heard of this? Is it a bad idea? Thanks, Sundance

It won’t be as accurate as the drops of reagent will have a greater volume. Other wise it should give you results I would think. In the end you are looking at the quantity of reagent dispensed from the syringe not the number of drops.

I supplemented it once a while back but have done two 20% and 2 or 3 5% water changes since. I also used tap water for my first fill. Why would some of the iodine's be high and some low?

I just got my Salifert Iodine test kit. The test on my water has raised a number of questions and hopefully someone here understands the chemistry a lot better than I do and can help. The first part of the test is Iodide. The test states that if the color turns blue, purple or black the...

Is there a Po4 test kit that will show levels lower than .25? My kit shows .25 then 0 and nothing between. I have seen posts here saying .02 Po4 is what you want. I'm at .25 and still seeing lots of algae. Thanks

I just got some Sun Coral. On a shell stuck to the side I fould two little offspring. The grownups I'm feeding brine shrimp. What about these little guys. Will they do OK on their own filter feeding? They are about the size ( about 1 cm with everything out and a mouth maybe .5 mm) of a brine...

I see posts all the time with a number of photos. Do you post additional photos as replies?

How do you post more than one photo?
