I have a 10 gallon tank already established with plants and fish.
The floor is plain gravel (blue !!) of a larger size.

I'd like to build up a layer of substrate underneath it without
disturbing the tank too much.

I've read that clay can be made into balls, baked, then inserted into
the gravel.

Anyone try this or have any tips ?

When you mix small gravel with large gravel doesn't the large gravel tend
to rise to the top? You might try mixing some flourite with your gravel
and stirring it up a bit to get the blue gravel back to the surface. The
flourite seems to be lighter than gravel, though. Perhaps that is just
my imagination there....

Anyway, that might be worth a try since the flourite is an excellent
growth medium.

you can also crush the florite can't you?

Have no idea how well that would work. I think you would end up with a lot of
dust and fines. The Flourite is only 1-3mm anyway.

The only stuff I see in the stores locally are the 20kg bags and that has
the 5mm+ granules. I've never seen smaller granules, nor have I seen
smaller packaging, which sorta bites, I don't want to add another 10kg of
gravel to my tanks.

Hmm,

Someone in my office suggested filling a tube with the substrate you want
and somehow blocking it from spilling out, placing the outlet at the level
you want in the existing gravel and then somehow opening the bottom of the
tube. Now I've used a similar technique when using cement grouts in wall
cavities but maybe the same could be done with a funnel and hose, you'd
probably spill a bunch into the water too

We are not talking about the same stuff, then. All of the Seachem Flourite
products I have seen come in 7kg (15 pound) bags.

Another option would be to use Profile Aquarium Soil. This is much less
expensive and seems to be uniformly smaller than Flourite. The down side is
that it is even lighter than Flourite and has the coloring of kitty litter.
You can find this at your local Home Depot.

For your 10 gallon tank, you would only need one bag of either product by
itself to get something like 1.5 - 2.0 inches depth.

Diana Walstad suggest wrapping up paper parcels of soil and pushing
them into the gravel. I've not tried retro-fitting soil, but I'd
recommend it as a growing substrate:
