I noticed a couple of these little critters crawling on a rock this morning. His actual size is apx 1/2 of an inch across. The colors on it are what have me completely confused. I have seen smaller, all white, starfish in my tank. I pretty sure those are just the astroidea. This little fella is...

I have a set of Coralife dual-bulb compact flourencent light fixutres (like this) on my tank. Some salt creep got up into one of the units has has corroded one of the sockets and that bulb no longer works (pin fell right out from the corrosion). Does anyone know where i might be able to buy a...

I can't believe they actually thought this was a good idea: http://www.miami.com/mld/miamiherald/15560115.htm

I know I would. Good ol' scotty from star trek was right on the money! Stronger than glass (therefore much thinner panes would be needed). More scratch resistant than glass. Lighter than glass. oh... and it'll stop a .50 cal armor piercing sniper round...

... and I'm addicted to the World of Warcraft. It has come to my attention that I am, in fact, addicted. Many addictions cause one to neglect their friends and family. Part of the recovery from addiction is to make right by those you've neglected. If I have neglected any of you, you have my...

I use an ATC refractometer to check the sg of my saltwater tank. Has been very accurate and a great tool for me. I was brewing beer with my brother a couple weekends back and I brought along my refractometer for testing the sg of the mash. (the pre-beer after first boiling the grains) The...

This is a little SPS (encrusting) I found on a piece of LR rubble (yes, same piece of rock as my other post). When I first got the rock it seemed to be just a coral skeleton. No polyps visible at ALL. A few days after I upgraded my NO lights to the PCs lights I noticed polyps! There were only 4...

Found this on a chunk of LR rubble I got from my LFS about a year back. I barely noticed it when I first put the rock in the tank. It was a tiny patch about 3/4" in diameter. This pic shows the whole patch has nearly doubled in size and is about 1-1/2 to 2 inches across. Slow growth I know, but...

I've been fighting a never ending battle with blue-green cyano (including completely draining and scrubbing the tank, gravel and plants) with zero success. I've been reading up lately on folks having good success with erythromyacin to treat the cyano. I've purchased a package of "Myacin" which...

Just thought some of you would be interested in the story. Discusses how (part of) our hobby is affecting the reefs as well as other factors affecting the natural reefs. As always, please do what you can to buy Tank bred livestock and aquacultered live rock. This promotes the industries efforts...

my system is coming up to it's 2 year birthday. A month or so back I added my first corals; a rock with two types of mushrooms. The day after adding them to the system they were in FULL bloom, better than they looked in the LFS. About a week later I noticed them splitting and multiplying like...

It seems like us reefers are always on the look out for old castle sand. Well it's the prime time of year for it to actually start appearing in the stores so I thought I would create a thread for folks to list where they've found it so others can get their hands on this elusive white gold...

I purchased a group of these float switches a while back as a number of folks here raved about them. I've been trying to think of an easy to make and easy to adjust mount for them. What have you folks come up with for mounting yours? remember, pictures are always helpful in this forum! :wink:

My mushrooms are reproducing like rabits! Since I bought the small piece of LR with them about a month or two ago I now have probably close to a dozen new mushrooms. I'm not complaining, honest. But they're all in that same little spot. Some of the bigger original ones have started to slide off...

during one of my frequent forensic level observations of my tank (I'm surprised I don't need to wipe nose prints off my tank!) I noticed this little fella... Bubble anenome? Coral? If you look close he actualy has a few siblings. This is on a rock that has been in my tank for over a year. The...

I'm extatic! Over the last couple of days I've watched my newly acquired mushrooms bud off 3 new additions to my tank!! And I have pictures of the process!! I feel like a proud new daddy!

I've recently added a rock with some shrooms to my system and so the time to keep on top of my Calcium and Alk have arived. I just did a 20% water change yesterday. Readings as of 5 minutes ago: Ph: 8.0 Ca: 310 KH: 7.0 (Meq/L: 2.51) What I've purchased to keep my ca/kh in check is Bi-Ionic as...

One of the most important visual points to me is the propper color of the wood when done. To this end, I've saved a few scraps of the oak boards I used to construct my stand and have been test staing the scraps trying to find the right stain, application technique to get the color and darkness I...

well... i did some experimenting and came up with this design for an EXTREEMLY cheap and EASY overflow that handls about 600 gph. THe last image attached below is the whole unit stretched out so you can see how things are linked together. The other two are to show you how it looks before it'll...

I'm experimenting with a DIY overflow (pictures will come once it works!) and I'm concerned about the flow i'm getting. I'm using 1 inch PVC but.. I'm using a Mag 9 as a test pump and the pump is winning hands down in about 4-5 seconds. Is my overflow carp or am I simply expecting too much of a...

this is a crop from a pretty detailed report on an LED. any thoughts on the quality of the light? The only thing I'm confused about is the spec sheet only lists "Candela" for the intensity. How does candella compare to lumens? anyone know?

I'm just finishing up a DIY hood for my FW planted tank (20g) and am debating which lights to put in it. I am currently considering this CFL by philips. I have these exact bulbs in the mirror in my bathroom and I like to cool white light it gives off and I think it would be plenty bright enough...

does that subject even make any sense? lol anyway, here's my latest brain child. Take a gander at the attached pic, return pump from the lower sump tank output to the output of the closed loop pump. Yes the output, as shown in the diagram. The basic venturi principle should "assist" the lower...

I hacked up my 10' of 1/2" PVC the other night and pieced together a closed loop. I currently have a mag 7 driving it. The pump is outside the tank. After hearing so many folks say that they don't even bother gluing their PVC pieces together, I dry fit it all together and turned it on. After...

I'm looking for a good grass-like or low bush (1-2" height) style plant for my 20 gal tank. I saw some pics, that I, of course, cannot find again, of some tanks with a moss like grass plant covering the majority of the bottom of a tank and I loved how it looked. Searching store sights I can't...
