I haven't had any ill effects yet. Now, I'm only running it in my 2g cube at the moment. I'll have a DSB in my 75g, but that's still one of those projects in the making Now, when I first started my tank, I had a little longer Cyanobacteria bloom than normal, but that is probably because of the purity issues of pulverized limestone. Other than that, all is good. Corals growing, fish living, critters digging, etc.

Thanks Travis, I picked up 200lbs for the 150 project I will be starting. I can't find any info related to concern brought up a few posts ago regarding the possibility of an unknown additive.

I think getting the generic, agriculture based limestone is going to be fine.

Nope, sorry Jarrod. And I probably won't. I'll have to dig up the information again, but crushed oyster shell has elevated amounts of phosphates in them. Of course, this is probably like any other non-pure substrate; you'll have to deal with the impurities and the consequences until they are used up or taken out.

Jarrod, here is a short read on it (page 5) http://archive.reefcentral.com/forum...73#post9171173

Thanks Travis.I do have a 19 pound piece in my tank that I made out of the oystershells.I wonder if its possible to leach out the phosphates?I was just thinking of the whiter color versus they grayish color of the limestone.

There is, kinda. Growing macro algae, doing water changes, and running Iron Oxide Hydroxide (GFO) Phosphate Binders. While you can't just "wash" the stuff and have it all come out, you can use these methods (which most people already use) to take it out as it comes out of the crushed oyster shell. Someone using this in rocks or on the substrate might see an extended microalgae bloom, but just let it run it's course and don't freak out. Even though it is growing and looks unsightly, it won't harm anything (as long as it doesn't overgrow corals). So, let the cyanobacteria/dinoflagellates/diatoms grow, and just syphon them out during a regular water change.

Works great for me. Two tanks so far and three more eventually on the way.

Working great for me as well on my 150. The only bad thing is the amount of rinsing you have to do to get it ready, but at under $5 for 50lbs, I was happy to put in the work

That's impressive because it took several hours to rinse and it looked like watery quickrete to begin when I started. Turned out just fine, just took a while to rinse

In the tank it looks fine, very white with scattered specks of gray and black. I'm talking about the run off water from rinsing it looked like watery concrete.

FWIW, I used the pavestone and hated it. It was like concrete mix, slushy and muddy, I still have it cloging up my pumps. I rinsed it for hours before I added to my tank. And a few months ago took most of it out. Just my experience, will get crushed coral next time around.

Hey Travis,
What exactly is the name of the stuff you used? I am having a hard time finding anything even close. Is it outside with the paving stones or inside? Kind of off topic, but kind of not. I am going to put a DSB in my refugium. What are other alternative sands to use if I can not find pulverized limestone? I guess I should say cheap alternatives if you get my meaning. The fuge will be for growing cheato mostly.

It's called exactly Pavestone brand "Pulverized Limestone". It's the exact one in the pictures of this thread and featured in my 75g tank build.
Right now it's hard to find because it used in gardening, and well...the weather...you know. If you're in a serious pinch, just gether Natural White color of Reptilite reptile sand by CaribSea. It's the exact same thing as their aragonite reef sand, just packaged in smaller amounts and labelled/marketed differently.

I have used it for a year now and its done fine by me but I washed the hell out of it because it did look like concrete mix but after several hours of washing and rinsing it worked perfectly well.

Hey all. Has anyone found this recently? In the crushed instead of powder form? I called my local HD and they only had the powder. Thanks...

Hmm, I had this in my 10 gal, and I never rinsed it out. I just had poured my water into the overflow and let it run down the sides to reduce the sand being kicked up.
After it became colonized, it was fine. I wonder if some people got bad batches? I believe Hefner, that you do not want the powder form. Also, welcome to the board!!! |
