coral skeleton

Hi everyone. I'm in the process of cleaning out my calcium reactor and changing the media. I had been using ARM media before and have always had troble keeping the calcium, alk and Mg levels stable despite stable CO2 and flow settings. I found some new media called GEN-X C.R.M calcium reactor...

First and foremost, I would like to say hi, I randomly stumbled across this site when doing research for my marine tank in the near future and these forums look like a collage of collected people of similar interests and information, so I figured it was a good place to start asking questions. :)...

Ever since day 1 the little joker loves to "hide" at the top of the tank. It is like his little area in the tank. He stays in the corner all day and night and will come to the front when I feed him. He has been a solo fish for over a month now and I was going to get him a friend and wondering if...

I have always wanted some sort of saltwater tank and I had a old aquarium and a stand in the garage so I took the plunge and started a really basic tank. I did a bunch of research and after lots of reading I decided that I am totally confused but with the knowledge I did obtain I thought I would...

Hi all, I have been waighting for the right time to add fish to my newly setup 20 gal tank. Everything is good with the tank but i'm worried about my new fish. I got two verry small clown fish and all they do is hide behind my power head mount accept for feeding. I figured they just need time to...

I currently have a 125 gal tank with 3 emperor 400's running in my fish only tank. no reef tanks in hawaii. I have decided I want to move to better filtration and I was wondering what size wet/dry I should get. specifically dimensions or gallon size of the bi-ball container. I know the sump can...

OK, I know you have all heard the rumors, so here is the official announcement. I will be hosting a get together on the East Coast in the Spartanburg, SC area for TRT at the Walnut Grove Seaquarium (my house) on SATURDAY, May 17th, 2008 from 12:30 PM until dark --RAIN OR SHINE-- (we'll have BIG...

Ok, I feel like I have a good handle on the basics of reef keeping 101. I measure this by the fact my current 180 sps tank is doing well. The sps are actually growing with what I consider decent speed and coloration. I have the origional two sps colonies that started my tank over 18 months ago...

This is a Octopus CR-140 6 1/2in dia single chamber. The water flow inside the chamber is so strong it is blowing the media all over the place. There is a bracket in the bottom of the unit with holes in it. on top of that is about a one inch thick sponge. Then comes the eight pounds of...

I'm a complete noob to this hobby and started myself a 14 gall bio cube, i got some live rock from the live rock pit at the lfs and picked out some varried lookin pieces. but i'm starting to think one of my chunks may not be live rock at all, but more like some dead hard coral or ...

Reg and I have been planning to put together a 40 breeder system for months. A few weeks ago, I finally found a new job (working in the aquarium industry no less!). This means we finally have the means to do what we first envisioned for this project. First, we both work full time, go to...

I wrote in last week about my brain not doing so well. I think I may have bought it already bleached. I placed it under a ledge and have been trying to get it to eat. I noticed some white under it. I guess its melting. Does anyone think it has a chance at this point. Any more suggestions.

Hi Guys and Gurls, I am in dire need of a replacement 3200 GPH Dolphin (Ampmaster) marine pump if anyone has one or knows of one locally that I can buy (even retail at this point, $$$, the days will make a difference). If I cannot find one by Saturday evening, I guess I will order one and...

I have a brother that lives in Japan. He is getting ready to move and would like to send me his corals from his tank. He has mostly Zoanthids. That leads me to the title. 1. How should we go about sending these corals? 2. How do you recieve these? ie. how to get them through customs 3. Which...

Ok, I know that Magnesium and Calcium go hand and hand, Strontium is also somehow added as well. What exactly are all the relationships with the three, how do they work together and against each other?? What levels of each are going to be most beneficial and stable in a reef tank, and if one...

I would like some clarification please. It is established that sand will absorb phosphates, and rocks will through wicking. Will rocks in a bare bottom eventually absorb phosphate also? What about crushed coral, argonite and other substrates? Thank you.

Purpple digi frag... this frag and a few more in later photos came from a little bitty piece that was overrun by xenia. I pulled the xenia off and left alone for 6 months.. viola.. Feathers at base of closed toadstool.. can you see the chromis? Zoas/palys I got from Todd.. they were...
