Marco Key Largo Dry Rock
Anybody who has used this rock from "Marco Rocks" experienced any issues with phosphates. How did you prepare the rock for the tank? I am thinking about ordering from them but wanted to get some feedback before I pull the trigger.
Thank you in advance! |

I've used it successfully in the past, and ordered it for a new tank that I'm setting up again. Most people report good success with it - if you want to be extra sure soak it in RODI water for a few days and find out if your specific rock is leaching or not.
If it is, you can treat with gfo, phons ban, lanthanum chloride, etc until the rock doesn't leach phosphates anymore. For what it's worth you can have the same issues with real live rock

I've used a few hundred pounds and never experienced elevated phosphate levels from it

Any of you used their aroganite sand? How fine is their "fine" sand?

Apparently, Florida is full of phosphates...
FGS, Florida Minerals - Welcome | Florida Department of ... http://www.dep.state.fl.us/geology/g...s/minerals.htm Phosphate - Florida producers supplied approximately one-quarter of the world's phosphate needs and three-quarters of US domestic needs.

I just went and tested the RODI water I've had some soaking in for the past week - 0 PO4.
I'd recommend testing your rock, who knows - it could be different. It's easy to do.

Marco Key Largo is fantastic dry rock. Porous, lightweight, and zero phosphate issues. I used 150-175# of it as base rock in my 465 gallon SPS tank, and placed my live Totoka from the old reef on top of it. No PO4 issues in two years, and I have never heard mention on RC or any other Forum about phosphates from it period.
The stuff stacks and locks together like a jigsaw puzzle. Great for building a reef structure.

I've had 150 # of it in one of my tanks for about 16 months now. Never had any problem with phosphates.

Thank you all for your contribution! It seems the majority of people have not experienced any issues with the rock leaching phosphates. If I decide to go with this rock I will make sure to test it before using it in the tank to make sure its phosphate free

I tried searching and didn't find any threads of phosphate issues.

It is the BRS Pukani that has to be acid washed, apparently. The Key largo is just rinse and place. There are no organics on it since it is quarried.

I ordered 100lbs of marco dry rocks. No problems at all. Just make sure you leave a message at the checkout to package the rocks with extra padding. I had lots of crumbles two make two big rocks. Overall, nice rocks!!!

MarcoRock does ship each rock wrapped separately. Some does break anyway, but most arrives intact.

I used about 25 pounds of Marco rocks in my 55. It has been running for about 4 weeks, the rock is still clean, It may be early yet but very little algae except on the live rock I bought last week and today. I did not even rinse the rocks before filling the tank. We will see how it goes.....
