If one has a ballast and socket kit for straight pin power compacts but has some old square pin bulbs lying around, is there any kind of adaptor one could get ot use the square pin bulbs in the straight pin sockets?

Tonight while working on my canopy, I dropped a steel screw and screwdriver bit into my tank and it has been lost in the rock structure. Did I mess up big time? Will this affect my fish or corals in any way? I realize that the screw and bit will corrode and release iron into the water - will...

I have a Kent Nautilus ex 24" venturi skimmer and it is producing no bubbles whatsoever. It is in sump with a 6" length of flexible pvc to the pump which is a quiet one 4000. I don't know what could be wrong here. It has been setup now for over a month and still producing absolutely no...

OK, here's the deal. I'm just getting the plumbing set up on my new 125 gallon tank and I have never been so frustrated in my life.... I have two overflow chambers with those standard All-Glass overflow piping kits. One is running a closed loop so it overflows into a 1 1/4" pipe which is...

Title pretty much sums it up... the center support of my 55 gallon aquarium let go with a loud band last night. I idn't even realize what it was until this evening. What do I need to do (if anyhting) about it? Is it safe like that?

I have heard it said, on normally good authority, that the default --- for these fish is male. Is that right? It would seem to be at odds with most other species. Anyway, I ask that question because I have a female but would really like to have a male but I dont think I have room for another...

I'm moving this weekend and taking the opportunity to upgrade from a 55 gallon to a 125 gallon. I have a mixed reef tank and will be moving to the same. Can I just take the stuff from the 55, add the extra water, and move it all into the 125? Or do I have to cycle the 125 first and transfer...

My question is: if you put frogspawn corals in high light would a) their zooxanthellae multiply to grab the light and "brown up" the coral, or b) their zooxanthellae become less prominent due to higher light conditions and therefore less demand for light absorption and then the coral becomes...

There have been a number of posts on the board of late suggesting that iron is critical to success with goniopora corals and that it should even be supplemented. This is the first time I have come across this info and I was wondering if anyone else has had any experiences that might indicate...

I'm about to setup a new 125 gallon aquarium. It has two overflow boxes predrilled and two drilled bulkheads. Below you'll see a diagram of the flow layout. Basically it's a little busy but what it is trying to show is that there is a main system pump that takes its water supply from one of...

Well, it's not exactly new. It's been up for about 3 months now. It is a 12 gallon JBJ modified with 96 watts of PC lighting. It has the pump replaced with a 150 gph pump and another small submersible pump (you can't see it in the pic) around 90 gph behind the rockwork. Corals include...

Well, not yet anyway. I am moving from a 55 to a 125 gallon tank and I just recently purchased a Kent Marine Nautilus EX 24" model as the primary protein skimmer. The skimmer is rated for 400 gallons (I think) but based on what I've read on this (and other) message boards., it will probably be...

I purchased this online a few days ago and it came to me by air yesterday. The bag it cam in smelled rotten. It looks like a few of the polyps will probably die. But more importantly, I paid $350 for it under the impression it was an Acan Lord. Which I don't think it really is. Anyone care...

I bought this coral yesterday advertised as "alcyonium sp." at the store where I bought it. I'm not quite sure it's classified right. It seems to "hard" to be alcyonium and the spicules seem too prominent. When you touch it it's like its made out of wood almost, it's so stiff. Anybody want...

Anybody have any idea what might be happening to this Capnella? I have had it for about 3 months. That whole time it has looked like this. It was originally in my 55 gallon and I tried it in a variety of places in the tank. It seemed like the more light I put it under, the worse it got. I...

Hey anybody ever seen this happen before???

I've got a piece of LR in my nano cube covered with these things. Any idea what they are?

What do you think this is? I bought it as Nephthea species but do you think it could be more likely to be Capnella?

I just recently bought an ORP monitor to use with an Aquamedic denitrator unit and I just decided to measure the ORP in my display tank. It was only around 80!!! My understanding of ORP is that it needs to be somewhere betwenn 200 and 400. Shouldn't my tank readings be incompatible with life...

So I'm soon going to be building my own house and I was thinking of setting up a custom tank in the living room. What I was thinking of was a 4 foot by 4 foot by 3 foot deep "cubic" aquarium with a central overflow. I was also thinking about setting up a "stepping" system of pvc pipes around...
