I received this tank for free from a friend. I was going to clean and resell. Now I am interested in maybe keeping and moving my 75g over to this tank. However, I'm not sure how this overflow works. The main overflow is in the center of the tank with several dividers on both sides. At the...

So I did a water change and good tank cleaning on Tuesday. Today when the lights came on I noticed several of these bright lime green tubes. I watched all day to see if something would come out of them but they just hung there. They were not there on Tuesday and I have never seen them before...

What is this? I have several that rode in on a piece of LR and now they are growing in my tank. Are they good to have or should I start weeding them out?

I was wondering who all is running tanks with refugiums? I got my HOB fuge about a year ago and was enjoying it. My problem is that between my Super Skimmer leaking and my fuge leaking I just had to replace my 72g bowfront (the stand was all warped) with a 75g tank and oak stand. I upgraded...

I am going to need to buy a new tank and stand and was wondering if there was anything special I could put on the stand to protect it against leaks and salt buildup? My current stand is getting warped due to some water leakage from my HOB fuge and just wanted to see if I could avoid this...

This crab showed up about 2 months ago and was small and white. Now he is getting bigger and darker. I'm not sure what kind of crab he is and if I should take him out. Any help appreciated.

I feel like an idiot asking this question, but I am having trouble figuring out my refractometer. I can see it, I have calibrated it, but I am thrown off by the numbers. I am used to reading SG and seeing 1.026 but now I am looking at salinity readings and my refractometer goes to 30. I...

I just wanted to poll everyone and see how they are cleaning their glass. I am getting some BIG circles of coraline on the front and side glass panels and it is sooo hard to scrape them off. Just wondered what everyones solution was and what instrument they were using to clean. Thanks in...

I got a new Coralife Super Skimmer. I know that they are very "touchy" skimmers. However, mine will not produce any bubbles. It is brand new just out of the box. Any idea's on how to troubleshoot?

My starfish has a HUGE hole in its head. It came out tonight and was curled up with the smaller red starfish and I thought that it had eaten my Mandarin by the way the hole looked. It has some blue and red coming out. But to my surprise I found my Mandarin swimming around. I kept looking at...

I bought a feather starfish a couple of days ago and have been trying to figure out what they eat. It seems very happy in my tank right now but I don't want it to starve to death. I tried to hand feed it a piece of clam like my other stars eat and no luck. Any suggestions?

How long is too long to be missing a yellow goby? I haven't seen mine in weeks. He used to follow my cleaner shrimp around and I have been missing him. I looked all over to make sure that he didn't jump out. I have glass covers and also a canopy so he would have to be very determined to...

I have decided to construct a refugium out of either a 10g or 20g tank that I have at the house. I have been doing research and have come up with one question, Do I need a mag pump on the return line and another pump on the intake line? Or is there only one pump? Thanks in advance

My first stocking attempt is not going so well. Last Tuesday I went out and bought 4 pajama cardinals and one blenny. By the next morning one was dead. OK, I just thought that it might have been a fluke. Friday on my way home from work I bought two more. I know that they are school fish and...

I have someone offering me an orange sponge b/c their child wont leave it alone. I have not added my livestock yet (only the damsels for cycling) and was wondering if I should take it? Are they hard to keep? It sounds like everyone on here has a sponge or two. What do I need to feed them...

I just got skimmer up and running today and I have a problem. It is a JEBO 180 skimmer. It runs great but I have A LOT of tiny bubbles flying out into the aquarium. If I tighten the air flow knob shut they stop but the water fills all the up into the collection container, and the flow is so...

I have my new tank up and running, since yesterday. I have nothing alive in it yet. I have my hydrometer inside which is reading high, but my temp went up to 84 last night. I turned it down slightly this morning. My question is, is there an easier way to determine salinity and specific...

I am new to the saltwater world but currently have a 125g freshwater cichlid tank and a 10g fry tank. I am trying to get all of my equipment together for a 72g bowfront saltwater tank. I have read one book and have two more on the way. I have a question, I read in the book about making sure...
