View Full Version : Gray Coast?
I am hoping to get some more specifics about this product:
Where does it come from? (I am not looking for an address, just a region, like Fiji, Hawaii etc...)
At what pH does it actually begin to "buffer" the water? (Higher or lower then traditional Aragonite sand?)
Being so high in Magnesium, do I have to worry about elevated levels of Magnesium, as compared to NSW?
Is this product to coarse for me to use as a traditional DSB, with sand dwelling creatures, like N. Vibex, misc worms, and other "mini stars"?
I am moving in February, and this product has recently been recommended by Mr. Calfo, but before I commit to this, I would like a little more information.
Thanks for the response, however the link you provided is broken. Can you please check that for me?
I think I have found the link you wanted me to see,
Now the question is, is this product synthetic or biogenic? Please understand I am not trying to be a PITA, but I want to make sure I do my new tank up as best I can.

It is a mined product and is not synthetic.
I have put both Seachem Graycoast and Seachem Meridian in a brand new tank with water.
How long does it take for the 'dust' to settle out of the water?
I have a small filter in the tank and just put in a smalll heater. I have not added the Seachem Reef Salt yet.
Is the water cloudy white because it is in the process of 'buffering' the water?
And if so does it need the correct temperature and salinity to buffer first?
I am asking because I would prefer to change the water many times BEFORE adding the Seachem Reefsalt, if I have to.
Thank you in advance for your help with this.

I may change the name of the thread in the future to: Salt Water Plants = Seahorse Tank.
It seems to be EXTREMELY hard to find information on growing plants in Salt Water or Reef Tanks.

It shouldn't take more than a day to settle depending on how well you have rinsed. If you have not rinsed it well, the cloudiness could be due to this. If you have any room to put some filter floss in, this will help speed the clearing up. You could also use some Clarity along with this.
You will need to add the ReefSalt to the water before adding the water to the tank in order to mix it well. If you have freshwater in the tank right now and you are trying to keep a saltwater tank, you will need to replace the freshwater completely with premixed saltwater.
Seahorse.org has a really good forum with some info on keeping a seahorse tank. It also has a section on the forum about keeping a marine planted tank.
Here is the link: http://forum.seahorse.org/
We are in the process of expanding our articles section on our website and there may be some articles available that will help with keeping saltwater planted tanks.

This is encouraging.
Like I said, finding good information on this topic is NOT easy.

You are welcome.
