    Clam Identification

    That clam is Tridacna deresa. I have a few Tridacna, but not that specie. A source for info on Tridacna is Daniel Knopp's book "Giant Clams". Knopp also has written some on-line articles. Deresa's can get quite large and have a reputation as being one of the easier clams to keep. Two...

    Lets Talk About ~Filtration Concepts~

    Doug, thanks for responding. Could you guess what your flow through the scrubber was, and what was the flow relative to the display tank volume? Do you intend to include an ATS in future set-ups? If not, what style tank do you think you will be moving towards? I've figured a way to surge an...

    Lets Talk About ~Filtration Concepts~

    Doug, I'd be grateful if you'd elaborate with more details about your ATS, how you used it and for how long, and what you thought of it.

    MH lights Question

    I'm sorry, Kevin, but I think you misunderstood that Mark was referring to a 250W ballast. A M81 (250W "HQI") does not drive a bulb harder than a standard M58 (250W probe start), which is what I believe that the eBay listing shows. A main difference is that the M81, and all "HQI" ballasts, has...

    Nice place you've got here...

    Nice presentation you gave at our PSAS meeting, Jon. Setting NSW constituants at unity, then showing how different methods of water husbandry makes the constituants in our tank water differ from unity was a good way to explain it for me to understand what you were saying. Hope you'll come back...

    Group purchase Fritz super salt concentrate?

    Thanks for the inputs, really. But I'm not currently interested in where to get inexpensive IO or the merits different of salts, in general. There are plenty of threads over the last year on RC for those people who want to discuss or read about the merits of salt mixes. I'm looking for people...

    Group purchase Fritz super salt concentrate?

    Fritz Super Salt Concentrate Same product sold through Aquacenter commercial supply Aquatic Eco System sells the same stuff, repackaged, as Proline Salt Concentrate. I'm trying to gage if there is enough interest in using Fritz salt concentrate to justify going through the effort to organize...

    Need dontations or cheap corals, fish for school tank

    You are welcome to these goldstripe Premnas , but consider potential conflicts between them and other anemonefish in the tank. I also have a blue Mespilia globulus (tuxedo) urchin to give away. I have Sargassum sp and sand-associated Halimeda sp plants that I think are appropriate in a...

    Most Sought After SPS's

    The very pink, very fuzzy Stylo that they have in the show tank at Waves (eCorals) in Portland. Not the digitate one with short polyps that is readily available. This one has a rounded shape more like P. damicornis, with fuzzy tentacles that shimmer in the current.

    What Have You Fragged?

    I accidentally split a Cycloseris disk coral after Calfo's talk. The coral had been severely damaged coming from the seller's tank, and never re-grown over all of the recessed skelteton after several months. Algae encrouchment was becomming a problem. I was trying to clip back the back the...

    Chelmon rostratus-Copperbanded Butterfly

    Minh, my tank is overgrown with small fanworms and tiny colonies of hydroids to the point that I could really use a grazer of such things for control like a CBB. The warning I always get is that CBB can turn on Tridacna or certain corals. My instinct is that the risk is overstated and it...

    How to clothe barebttms

    The basic idea of the starboard is to put a liner for mechanical cushion between the rocks and the glass, in case the rocks tumble. Starboard also gives the bottom a white color, initially. If you are not concerned with tumbling rocks damaging your tank, you could just use the glass bottom...

    Great meeting!!!

    I could see that the leadership of PSAS and some helpers obviously went to a lot of trouble to organize and prepare the Calfo talk, frag give-away and raffle. I was thinking as my little group rushed off to catch the ferry that the least we could have done was stay and help clean up. Sorry to...

    flatworm treatment?

    Hi Heidi, My refugia has a large population of red planaria. They appeared after I introduced 20 or 30 pounds of rock to the refugia from another reefers tank after the last frag swap. I believe that this reefer had previously had a problem with red planaria, and had treated his system with...
