No problem Steve. I have noticed that there are different types of domilite lime -- some have chemicals in them that make it easier to spread on your lawn ($10 a bag). Just look at the label and see if they add anything special to it. It should contain mostly calcium carbonate and magnesium carbonate.

Basically, I look at the mesh size and if 50% is bigger than mesh size 100 and 50% is less...than its good enough for me. I also look at the guaranteed composition and make sure its mostly Magnesium Carbonate and Calcium Carbonate. Lastly, I take a sample of stuff and dunk it in saltwater. Wait 30 minutes. And measure the pH. If the pH goes up...this stuff has kalk in it. If its stay the same, then its good.

As for it being too fine. I thought that would be a problem at first. When you plunk the stuff in, its going to make your tank look like milk. After a couple of days, it will settle. After a couple of weeks, the bacteria and algae will start to grow on the fine sand, and the fine sand will always sink.

If you think it is too fine, you can add a bag of crush coral or something similar.

Hope that helps.
