Hi,

Sounds fine...I would check if the lime desolves in water (i.e. check if this stuff is like kalk) by checking the pH when it is in water.

I would also check if the lime is relatively pure (i.e. not too much black bits and non-CaCO3).

$3.89 a bag is pretty expensive though...I got my from Revy for $2.50. I didn't like the HD kind...it was not as fine as Revy's and it was not as white, although HD was cheaper ($2.25 or so).

hehe we are on the island add at least a buck for shipping hehe.. one bag was split so I am going to take a baggie ther tonight and get a sample and try it in water. althouht my PH is 6.8 so it might go up some..

the broken bag was all white.. like baby power white would look beautifull in a tank I think...

Hi,

Ummm...really...$1 for shipping. I grew up in the pacific northwest BC (near the Skeena river) and my parents live up there. They told me that lime is about $2 up there...and its about a 1600 km road trip to get there.

But, it sounds like the right stuff.

Hi,




BTW, X mesh means there are X squared openings per square inch. So, a 100 mesh has 10,000 openings per square inch (each opening is 1/100th by 1/100th of an inch).

and

1 inch = 25.4 mm.

So

1/100th inch = 254 um or 1/4 mm.

yup I know all that.. I use mesh sizes at work for various oil, water, freon, ect filters and strainers.

I currently have crush coral with agraganite sand on top, and I was told that this was a big factor in why I have such a high nitrate concentration. I am thinking of switching over to domilite lime. Is there a way to easily separate the crush coral from the agraganite? Is it worth while to try and save some of this stuff? I figure if I throw everything away, I will be removing what little worms and copepods I have. Can we buy these critters in to put into the tank? Should I move all my old stuff to one side and put the domilite lime on the other side and hope the critters migrate to the domilite lime? This whole thing is getting complicated. Is it even worthwhile to switch over?
