    Gemini - why don't you "JUST ADD" the 8kg's aragonite ON TOP of the DSB? The DSB will automatically "adapt" - the life fauna won't impacted, because they are burrowing in any case....

    How full? What is the "depth" of the water between the water surface, and just above the DSB top level?

    No man! You will MOST likely only loose like 2-3cm from the 14cm! MORE THAN ENOUGH SPACE FOR THE MUSSELS and CHAETO!

    I'm not jacques (lol) but will answer. It only tumbles on top of the DSB in the water.

    You don't "incorporate" it Brent. You just PLACE it there. Important thing about all/ANY nuisance macro algae is that it does not get into your pumps, ie skimmer pump OR return pump. It can STUFF up your pumps badly. I have my chaetomorpha in seperate "floating" "tupperware like type" containers, that I have cut slits in, that the water can flow through, but the chaeto cannot easily come out of.....

    You can use a 6500 kelvin globe to grow the chaeto. It also needs nutrients to grow, so if the nutrients are very low, it will look like the chaeto is standing still (not growing)

    I can't see that asking a question related to the subject is a "hijack" - that is how we learn, by asking ;)
