    Substrate

    Just wondering what the best recommended substrate is. I currently have crushed coral but am considering taking ~60% of it out and adding sand. Is this a good idea or should I take it all out and just use sand? My tank is a 35-40 gallon FOWLR.
    Thanks in advance for the suggestions!

    Hi Xena47r,
    I personally favor very little sand or substrate.The little substrate I have is araganite, which in my opinion is the best for Reefs.

    Thanks for the reply and the welcome!

    I have to ask though, I have never heard of aragonite. If you don't mind, could you tell me a little more about it? Sorry for being such a newb! And thanks in advance!

    Hi Xena,
    Got this from a write up I have on araganite.

    Aragonite is a naturally occurring, calcium carbonate mineral. It is precipitated from ocean surface waters mainly by organisms (e.g., coral) that use it to make their shells and skeletons. In recent years, aragonite has nearly eclipsed all other marine substrates. This is chiefly because of it superior buffering capacity. Aragonite becomes soluble at a pH of 8.2. At this pH, the release of calcium and carbonates into the aquarium causes an upward shift in pH. This occurs so slowly, however, that aragonite is less of a viable buffer and more of a safety net. With aragonite in the aquarium, one can be reasonably sure, that the pH of the system will never go below 7.7-7.9. Additionally, aragonite's porous structure and size make it ideal for the propagation of denitrifying bacteria.

    Aragonite is a common carbonate mineral. It is a polymorph of calcite. Carbonate minerals with this same structure as aragonite belong to the Aragonite Group of minerals. The structure is responsible for the similar properties of this group.
    In a good way Aragonite acts as a buffer to maintain your Ph and also some of your calcium levels.

    Yes, I am going up there today to find out if he has any or as you said order some in. The major problem with this is the cost of shipping. But he may be able to work something out for me.
