I recently have had a outbreak of flatworms in my 90 gallon reef. My LFS was out of Six Line Wrasse's, which I've read Love to eat these little pests.. So I picked up a Spotted Green Mandarin after reading online that they love flatworms. The mandarin is doing a alright job I guess...His belly...

Hi All, I purchased these water meters in bulk with a bunch of friends who also have salt water tanks. We have a few left over and I thought I am offering them to diffrent group members at a discounted price. The JBJ model of this meter sells for $100+. We are looking to sell them for $60. It's a...

Is the clown/anemone relationship a learned one or is it genetic? In other words will a clown take to an anemone if he has never seen/witnessed another clown fish in an anemone? I am asking because I have a tank raised percula clown who is not taking to my sebae or condy anemone. thanks.

It's time for me to propagate my Sarcopython. It's huge. All sites I have visited to propagate say to cut off the cap, cut it into sections and glue it to plugs or small pieces of rock. Because it's about 10" high I was wondering if I can cut it closer to the base. Does it need to be cut close...

OK I took the plunge. Ive got 100 lbs of Rock on the way for my 65 gallon. As some of you might have experienced, the internet can sometimes be an imformation overload. I`m Planning FOWLR . I`m not sure I`ll ever want to upgrade to a reef tank, but I DO know that I dont want to have to move fish...

hi, First of all---thanks for all the response Ive received on the NG. You have been VERY helpfull and patient. But I am SO frustrated. Here is my situation: Back in the 80`s, my wife and I enjoyed a great 45 gallon marine tank. It ran on a cannister filter, and an undergravel filter with...

Hello, I came home from work on my lunch break yesterday and thought that I was missing a clown fish. After putting a bit of dry seaweed in, he came out from hiding in a far corner under some pieces of live rock. For my clowns, this is VERY unusual behavior. They usually don't even go down to...

In a reef tank I use Instant Ocean salt. Can I simply use different salt, like Oceanic, for a water change or something bad will happen? Can I generally mix and match salt brands in a single reef tank or this is not recomended ?

OK--- been getting LOTS of great advice. Is there a power-outage contingency? What if you go away for a week and the circuit breakers go? I guess the Live-Rock continues to do some work for a while---but are there battery systems out there that kick-in in case of power outage?

Reading Borneman on the capnella/tree coral and he says they rely more on dissolved nutrients than xooanthellae. By dissolved nutrients, does this mean organics dissoved in the water column, or extremely fine food particles like zooplankton or prepared meaty foods? Thanks, Mark

hej, we live in northern europe, and have experimented with reef aquariums. Our live rocks (filled with algae, anemones, seaplants and tiny brushworms) are growing great.. and we just found a little, white hairy crab inside, which is getting ready to leave his crevices (probably getting too small...

"Natural Reef Aquariums" by John Tullock is the book Ive been using to research starting a reef tank. The guy seems to have all the bases covered. In his 50 gallon,36" set-up he includes a Yellow Tang in his habitat. Most of the tank requirements I see on the internet suggest a minimum of 70-100...

Plenum: from what I read It sounds like its just a raised platform so that there is water below the sand level. Would a capped,un-connected undergravel filter be suitable to use as a Plenum? I havent set my tank up yet so I still have time to do this. Is using a Plenum better than not using one?...

I had to help out a friend get some livestock, etc out of his tank. I know three of the fish but these two I'm not sure of. I'd appreciate the help. I know I've seen these before while surfing but now that I need to know, alas I cannot find them. (Yeah I was a bit amiss that he didn't know...

I just bought a condy anemone. What if anything should I feed him? The guy at the LFS said nothing.

I am leaning towards TONGA live-rock. Im cycling my tank with it. The Drs. Foster and Smith site have it for about 3/5 the price of everyone else. Are they cool? Alternate suggestions always appreciated.

I've had a group of three Purple Firefish for quite a while now, at least a year. Recently, one started losing weight and finally expired. Now, I notice one of the others is looking a little light, and I'm worrying. The other fish in the tank are eating and keeping their weight on. I feed everybody...

I am looking at various brands of PC bulbs online, and am wondering about some of the brands I am finding. Has anyone had any experience with the "True Aqua" or "Jalli" brand? Sometimes it's the same bulb under a different name, and sometimes it's not:) Thanks, Mark

Hi guys, I've had a 30 gallon reef tank for the last couple of years and I've decided that it's too much trouble (for many different reasons). Currently, I have some live rock with some riccordea, some green polyps, two leather corals and some miscellaneous mushroom anenomies. I have PC...
