I'm running ozone for two reasons. 1) It clear up the water a lot. Got the same effect of running active carbon, but with ozone, I don't have to keep changing the carbon. 2) I added some new fish. I do have a quarantine tank, but it's only 25gal, so doesn't work well when I add 7 lyratail...

Looks like some bubble algea is on the shell. Next time I stick my hand in the water, I'll scrap off the algea off the shell. The clams are on rocks under the sand. :) You're probably right that sometime had happened to it months ago, but what can cause it to bleach slowly? I don't think...

Here's the picture. Corcea on the left is bleaching.

I have 4 clams, two of them are corcea clams. I have them for over 3 years now. However, recently one of my corcea clam is bleaching slowly for 3+ months now. What can be the cause? I haven't change the metal halide bulbs yet nor did I lower the distance to the water level. The other corcea...

My tank is 180gal reef setup. I only have 4 large blue tangs and 2 clown fish. The ORP probe is hanging in the overflow box. I read that during feeding the ORP reading should drop, but mine stays the same. I'm not too worry about my water quality but more on if the equipment is working...

I recenty purchased a red sea ozone with controller rated at 100mg max. When I hook up the probe, my tank's ORP measured at 230. I have fed the ozone at 40mg/hr into my skimmer for 2 days now and my ORP reading still stays around 230. Does this sound right? Daniel

Hi, My sequmose clam lost its foot today, but it still looks ok. I heard that some clams will loss its foot once it get big enough. I never had this happen to my clams before. Usually how big do they get before lossing its foot? Right now, it's about 3.5"-4". Daniel

yes, I have lost many fish to an elephant ear. Then I took the elephant ear bak to my LFS.

I'm thinking of getting an anemone for my clown pair, but how do I keep an anemone happy in one place? I have a 180gal tank with lots of sps and clams. I don't want the anemone stinging other corals and clams.

Please help me ID this snail. I see several of them at night. I haven't seen any on my clams. Are they good or bad?

Anyone live around Portland, OR have a Velvet Nudibranch that need a new home full of flatworms? If so, please let me know. I can't seem to find them. Thanks, Daniel

Are they good or bad for my reef tank? Daniel

Have anyone seen this before? What is it? I have thousands of these things in my tank. They are very small.. roughly 2-10mm in length. When I cup one of them out, I can see it move very slowly. http://genji.image.pbase.com/u10/da...80.CRW_0177.jpg Daniel

I just brought a nice size acropora (5" diameter) last week. Two days ago, my two green Citron gobies decide they want to nest in the acropora branches. Today, they have ripped off 50% of the tissue mass from the entire acropora!! Do these gobies require that much space to nest? I have...
