so i've tried contacting GARF, and i've visited all my local Home Depots and Lowes, and i cant find anyone who sells low alkalinity white cement. I need it to make the magic aragocrete mixture. According to Portland, quikrite supplies their white cement, but according to quikrite, they have no...

Thanks guys! What I plan to do is mix up some aragocrete and pour it onto some eggcrate that i've measured for the walls, let it set, and then build stuctures and whatnot onto my new rock wall. Do you think this is a good idea? most things i've read about aragocrete say curing time is 6-8...

So I'm designing a new display tank, its a 200gal display in the main lobby of my building. I want to build a natural looking reef structure without having to buy hundreds and hundreds of pounds of coral base rock. Any suggestions? A friend mentioned using concrete and molding it how i want...

I've come here for suggestions on buying some coral taxonomy books. Is Corals Of The World (3 Volume Set) by J. E. N. Veron any good for taxonomy?

any suggestions on where i can purchase said bulb?

METAL HALIDE 400W 14K BULB with METAL HALIDE 400 WATT ASSEMBLED BALLAST (both supplied via Hamilton Lighting Technology)

any ideas?

hmm,... well they are research aquaria, and i'm supposed to be the only person handles the tanks... but we recently had a new PhD student come that thinks she can take samples whenever she wants, and may have used a rusted razor to scrape some xenia off the side of my tank.... hmm...

about a year and a half now.

Hey all, I've been slowly trying to increase my light levels over the passed year and a half by lowering my lights, right now they are at the lowest i'm comfortable with putting them, and the light intensity is barely 400uE. (microEinsteins). (I maintain coral aquaria for research at rutgers...

well, he's still alive, but hasn't moved much all day. He's got one spine left, it looks terribly sad. :cry: Also, the nubs where his spines used to be are red. Is this a sign of regrowth?

I measure salinity daily with a refractometer. I have float switches to replace evap loss, so the salinity doesn't change much more then +/- 0.5 during a given day. I have heaters and chillers working to keep the temp a steady 25 +/- 1. My pH is lower then i want it to be, but it is pretty...

I've got two seperate systems going, and ~2 months ago, an urchin in one system started lossing spines and died a few days later. Now this morning, i notice in the other system, yet another urchin is losing his spine... and will eventually suffer the same fate as his commrade. Any ideas on why...

I already did a search for my question in previous posts, but i haven't found anything helpful. I started noticing my Xenia weren't looking too happy, but the pH was steadily 8.2/8.3 But when i tested alkalinity, it was way low. I need to bring up my alk, what should i do. I have some...
