    Here you can check it out.. Some test that where done on it..

    I ran the stufff for over a year in a 30G tank.. and i moved the tank 5 inche deep and the sand was the same top and bottom.. No clumping.. nothing.

    Just to clarify aragonite and calcite are different forms of Calcium Carbonate, but their crystalline shape is slightly different.

    Aragonite is less stable so is considered to have more calcium buffering capasity than calcite. But so far I have only used Bomix(calcite based) and I am still in the preliminary stages to make any conclusions.

    From what I have seen of these Bomix bags in the stores, I agree with Venki that it is not aragonite based, although I thought it was silicate based, Venki says it's calcite based and I will believe him.

    I agree - Bomix Makes both silicate based (brown) and calcite based sand(white).

    BOMIX

    Yes the white Bomix is Calcite based and is perfectly fine for tanks. I've been using it for a few years now. Calcite is in the same family as Aragonite but is a crystal formation down from Arogonite. I also think it is from old seabeds. Now, I'm no scientist or chemist so this is just info I've learned and from using the stuff.

    Since my freshwater tank has been emptied, I'll be converting into a SW tank. I'll be tearing down my current 37 gallon setup (With Bomix as DSB) to make it a sump for the 72 Gallon tank.

    Anyone volunteer for this activity? you can get a first hand look at the life forms at different depths of the DSB. Beer is on me.

    Ivan,

    I'll take you up on the offer.

    I have sent you a PM with the things I need for the new setup can you give me a quote?

    May be we can set this up together some weekend. May be this weekend if you are free.
