Hi, I'm replacing my sump with with a sump/refugium and as long as I am doing this, I'm also going to hardpipe my overflow & return lines. I'd like to modify my external overflow box to hang at the bottom of the tank, but still higher than the sump. This is to to hide the box and muffle sound...

I have a bunch of what look like whitish pink "cocoons" growing on the underside of my rockwork. They are barely distunguishable to the naked eye, so a picture would be impossible. The only way I can describe is just like a cocoon, but faintly pink. Any idea what this may be? Especially if...

I've had my 55 gal set up for 8 mo. now and the warnings I had from people in here are coming true. I originally started with UGF, CC, on the advice of LFS. After joining AA, many advised me to tear out the UGF before I added too much. Well, I didn't listen and my tank parameters and algae...

I have something that I can only describe as what looks like an irregular shaped, orange human nipple with a black tip. It's very thin, clinging to rock, and flaps in the water stream. It's about the size of a penny. I can't remember coming across anything like this in my invert books, but...

I recently upgraded my lighting from std fluorescent to 2X65 PC 50/50. I got it from LFS for $150. LFS recommended just to put the strip over the open tank. I was leery of this (heat, contamination, evaporation) from the beginning, but after 3 days, I realized that I really need at least a...

This poor guy doesn't look good. I can't think of anything in my tank that would do this. The best news I can hear from anybody is that it is some kind of normal process, but I don't think so. Is there anything I can do for him?

I was trying to find posts/articles on the effect of using a flash for tank pictures. I couldn't find one, so I am posting. Can using a flash be detrimental to some of the nocturnal inhabitants ie. brittlestars? I seem to get the best pics when I use the flash, but I only use it sparingly as I...

I have abundant white, hard dots that stick to my glass. I have to use a plastic scraper to get them off during cleanings/WC. When I researched this before, I thought they were heteropods, but heteropods swim. These guys just stick to the glass (and rock). The pic isn't great, but it's the...

Hi, I just recently added a green carpet anemome to my tank. He was doing fine for the first few days, opening up, looking pink and healthy. He moved from substrate, over a rock, anback to substrate onother side. This is where he is now in the pic. He's benn like this for a 1 1/2 days now...

I just recently acquired an electric green carpet anemone. He aclimated just fine, and looks beautiful. As soon as I added him to the main tank, the 3 peppermint shrimp I have jumped on him like flies on This portion of your post has been edited, it is in violation of the User Agreement...

I just got a blue linckia and he's very rigid. I thought for sure it was rigor-mortis. He's been acclimating in a drip for an hour now, and I'll keep him acclimating and checking posts. He's still got great color, but he was shaped like an umbrella when I put him in acclimation pail and he's...

Hi. First pic shows a colony of tiny orange polyps on my rock that are starting to protrude and becoming tubular (I think). Is this some kind of sponge or coral? I'd like promote it's growth whatever it is. Second pic shows what looks like caulerpa (according to someone who only saw it with...

Hi, I have a pic here of something that looks like aiptasia anemone, but has white rings on tentacles and looks really cool. It's body is about a nickel in size. Hate to get rid of it. In the upper left corner, you can kind-of see what I think is really aiptasia. There's a second pic with...

had this Blu-Devil Yellow Tail Damsel since August when I started the tank. Everybody is doing fine except for this little guy. Last week, I noticed a vertical white mark on his body. Thought it might be a parasite, so I watched closely. Now, he looks like he has stress marks on the other...

I am at a sort-of crossroads. I have a 55-gal set up for over a month in which I was advised by LFS to start with 20lb live rock and hardy fish, coral substrate. My existing set-up was with UGF and two power heads, std fluorescent lighting, once again, LFS advised that would be fine for FOWLR...

Newbie questions... I started a 55 gal tank 3 weeks ago with crushed coral substrate, 20 lbs live rock, 2 damsels, & 2 clowns, 2 blue hermits everything is going fine, all chemistry is stable. Everything is lively. I'm seeing some cool stuff coming from the LR. I'm pretty sure the tank is...

I have a starter tank going for two weeks with live rock, 2 damsels, 2 clowns, 2 hermits. Everything is going fine. I feed dry flake at 7pm, with a light feeding at 6:30 am. My lighting is from 12 to 12. The fish don't seem to be awake for the morning feeding (clowns are a little). Should I...
