I had a saltwater tank for about 1.5yrs and had to tear it apart when I moved about a year ago. I'm starting my tank up again soon but it's much easier now that its all empty to get those 'upgrades' I wanted back in the day. First and foremost is I want to ditch my old canopy/hood and get a...

I just saw this little starfish in my tank. I was watching it for a few minutes then I saw it start moving along the LR. Anyone know what kind it is and want to make sure it's coral safe too.

Does anyone know of any cool coral reef or marine fish Videos, DVD's or TV shows on cable (such as Discovery, Animal Planet, National Geographic, etc.). Or any Video on 'keeping saltwater tanks' or 'reefkeeping'. It can be from any media source such as 'online videos' or DVD's.

I picked up a new piece of Hammer Coral from a buddy, pretty large, 5-6heads. I put it in my tank and within about an hour a few of the tentacles got really long and stringy. Theres probably about 7 or 8 that are like long, maybe 4-5inches long and stringy looking, all the rest are normal...

Has anyone ever modified a 'wall pack' style metal halide fixture to work for an aquarium? I know you'd have to change the reflector and remount the mogul but is it possible?

I was going to upgrade my lighting from PC's to Metal Halide but I'm reconsidering due to my canopy space. I'd pretty much need to build a new canopy again. The bulb would sit probably only 3"-4" above the surface and wouldn't have any protection, seems very risky to me, also even if water...

This soft thing is on my live rock and I can't figure out what it is. It looks pretty mushy and has 2 visible holes that look like they have white cilia hairs around the opening. When movement comes by the front the holes close up quickly. When I poke at it, it seems to close up and gets...

I'm looking for some new coral frags. Sick of my LFS's current supply. Anyone have anything and live in or near Orange County, CA? Please let me know. Looking for anything as far as LPS, leathers, polyps, cool shrooms, zoos and other softies.

I'm upgrading my lighting from PC's to a Metal Halide. Its for my 29gal tall fish/reef tank. I found a source that has 2 very similar setups available to me, both are Retro-Fit. I need a little help as to which one I should choose, since this is my first dabble into MH's as I've always had...

I picked up this piece of Green Tree Coral, it's about 6in. tall when fully erect. However it's not attached to any rubble rock or base. The cut part has healed up nicely but I'm trying to attach it to a rock. As you can see by the length of this post I'm getting really frustrated and ready...

I'm trying to glue down a frag of Green Tree Coral to a piece of rock base. Can this adhesive be safely used in the aquarium?

I don't now and never had a sump on my tanks. I was thinking of building one for my 29gal. The stand, canopy and placement of the tank make it hard to even have a sump but I was thinking about trying. The only thing is it would be extremely difficult to incorporate a HOB overflow onto the...

Does anyone have any experience with in-tank refugiums and ideas on how to make one. Would it be noticeably beneficial to have an in-tank refugium? I have seen several and am considering making one for my 30gallon tank. I can't have an external sump/refugium on it for multiple reasons, I...

I just noticed this thing growing on my live rock, it must of just started taking shape a few days ago unless I'm completely blind. It's raised almost like a half-circle dome. Looks like it has a coral skeletal structure that runs outward from the center radius. It's pretty symmetrical for the...

I just purchased a new refractometer and wanted to know about calibrating it. I'm sure I need to calibrate this before using it. It does have Automatic Temperature Correction but I need to know how to calibrate it. I know you can buy a saline calibration solution but is there anything else I...

Well I finally finished my custom canopy last week that I made for my 29gal show tank. The old one was modified to fit my new lighting but wasn't working out too well. The lights were getting very hot and the plastic cover started to warp, plus it was very low to the water and really heating...

Does anyone know of any effective yet not overly huge protein skimmers that can be mounted in-tank? I have a 29g tank with a custom canopy that won't allow for a HOB Skimmer. I wanted to see what my options are for filtering out free floating debris (I have no mechanical filtration, just bio)...

I have a 30g tank with natural filtration only (i.e. no filter, no skimmer). I have about 50lbs of LR and 40lbs of LS and 3 powerheads (tank turns over about 14x per hour). I wanted to see if anyone has any advice or tips & tricks with tanks that run natural filtration? Will I ever need to add...

So I know more than well about the facts of not joining multiple clowns from different species. But has anyone done it successfully and which pairs are best suited for the least chance of aggression towards each other? I'm sure some people have tried it and I believe it's probably just a...

I know everyone has their own opinions on what the SG/Salinity should be in a tank but I'd like to know what is best from 'personal experiences'. The reason I'm asking is because I used to have my SG @ 1.024 and some people told me they'd bring it down to around 1.020 because it's easier for...
