Idea on making "aquasoil"

Has anyone ever thought about how aquasoil is made? I've been reading lots and lots of posts on the web about other peoples ideas and what they think goes into making aquasoil. My idea was mixing bentonite clay as the "bonding agent" so it won't break down, humic acid, and mineralized topsoil (minus the clay), and then baking it in a kiln or oven. To get the round shape I'm sure there's a tumbler or a granulator or something. But I wanted to know what anyone else thinks about this.

This method might result in a usable nutrient filled substrate, but it won't make Aquasoil. I don't think this should be a concern to you. Just work out what gives you a good enough substrate at a cost and amount of effort you can handle. This method might end up being far more labor and time consuming than you want.

Wish it were possible to make it for I can't afford it. Thus after I break down a tank I will using a version of CO2 Generating Substrate.

Layred out so
1st Layer:
Blood Meal (Nitrogen)

2nd Layer
KNO3 (Potassium nitrate), Sodium bicarbonate (Baking soda), Scotts Hyponex Potting soil

3rd Layer
River Sand

Yeah, you're probably right, Hoppy. It'd be interesting to try, but its definitely way too expensive and labor inducive for anyone to consider doing unless they already have all the equipment and funds to try it. But it is a very interesting topic IMO. Some day someone will find a way to make a similar product.

Wouldn't the baking soda and sodium nitrate dissolve as soon as you filled the tank with water?

I think blood meal will generate ammonia, which is ok only if the level is low, and the water pH is controlled so it remains in the correct range. That potting soil may also contain ammonia generating materials. I don't think I would try this without doing enough research to be sure I wasn't creating a monster.

No, for there is a 1.5 in of sand over the substrate.

I have not had any problems with the potting soil I have used for a few years. The blood meal I read about here.

The recipe in the link says for the bonemeal to use "1 desert spoonful per 30 cm square." That's not enough for me to worry about amonia.

You have done the research and are careful about how you apply it, but a random person, who just assumes he can throw this stuff together can look forward to problems.
