    My first tank I used live sand from the beach, I've just upgraded and aragonite was recommended, apparently it helps with the PHOTO, Alkalinity and calcium levels for corals. I must say it looks a lot nicer than the sand. Only draw back is it takes 24 hrs for the water to clear as It gives off a white cloud when you fill the tank. Hope this helps. I bought mine from my LFS at Greenacres. I see you are In George not sure what shops you have there if any.

    id personally reccomend aragonite every time, it gives one a number of advantages in a marine system over other types of substrate.

    try get one that is 1-3mm particle size as that will give you the most stable envitonment for micro organisms to grow and will be heavey enough to resist the currents created inside a reef tank.

    also when you add sand (what ever you choose) remeber to have water in the tank first and leave some space for the displacment. this way the sand falls through the water and releases any air or gasses which would be trapped if you added water to a dry substrate.

    I'm starting a tank soon. And I've opted for Aragonite Seaflor 1-2mm.. 18kg would be around R600-R700

    Crispy, this has always got me thinking as to why this is recommended. Why would trapped air effect the tank/substrate.

    Butchers is surface area not surface area. Do you imply that trapped air will change the surface area? I would have thought that the viscous of the air to the substrate/ water would not alter the surface area.

    Beneficial bacteria can't live in air, but in water therefore more air less area for the bacteria to live on. That's how I see it.

    This subject has many opinions and will derail the thread. Perhaps move this discussion.

    Back to the discussion. I thought that air and/or the lack of it provided O2 and CO2 to the different bacteria.

    I am thinking, wet dry filters, trickle filters, Deep remote sand filters, bomb method with bio cubes etc

    thats how i see it too.

    i see the trapped air as being a blockage for aquatic life to live in and thus the area around the air reduces the surface on which bacteria and organisms can collonise or burrow through.

    personally where the difference lies between air trapped (static) in a substrate and the O2, CO2 you are refering to is that O2 and CO2 are disolved in water, which is not the case as in the gas form of trapped air. Also with the trapped air being static it forms a barrier through which aquatic organisms (from microscopic to bigger organisms) cannot pass through, as well as a barrier for which liquid cannot pass through. Its this barrier effect thats always concerned me most, not so much the reduced surface area, although there is that too.

    thats how I see it anyway.

    another advantage of substrate falling through the water collumn is that you rinse it well, causing a milky sand storm for a few days, as opposed to that fine particle matter being released each time a flow pump or fish disturp the substrate over a long period of time.

    Crispy, I understand what you are saying. And it is important to have discussions and for members to understand different points of view. They can then do research and choose the route to embark on. But IMO I feel that there are a huge amount of myths and " hear say's" that are fed to newbies. I do consider the traped air one as a myth. For all the reasons anyone can think of. Just my experience.:thumbup:

    However for many years we have always aquascaped, first to lay down the dry rock on the tank bottom. Glass or acrylic. Then add the substrate. Allow the aquscaping fixing and glue to set, then add water.

    As we set up and move at least 50+ tanks a year. I am sure we would have found a problem if there was an issue with trapped air.

    Maybe we are derailing the thread a bit...
    I agree with Keith, are bubbles a major problem? My sand bed has developed gas pockets, which I assume are a byproduct of anaerobic bacteria. Are these bubbles an issue? Would the oxygen trapped in the sand from filling the tank not be used up anyway?

    Hey man I just changed from crushed coral to React Eco aragonite live sand and it looks amazing. Will post a pic for you to see, my tank looks much brighter now.
