Aquarium gravel as soil was created by Mikayil

Hi there.?
I am in Azerbaijan, and we dont have proper bonsai culture. So shop where I bought my Sweet Plum bonsai planted it in full peat. It was hard to water it as water was not draining at all. We do not have pumice, akadama, or any other soil mixes here. So I came up with an ideo of using my old natural aquarium gravel. This gravel is a mix of basalt, pebble sand, and limestone. I mixed it 40%peat and 60% mixed gravel. Now water drains well. Did I do the right thing under these circumstances? I know that basalt is good for any plants. Not sure about the rest. Is this solution better than letting my bonsai stay in peat? I have 2 bonsais at the moment, bought them couple days ago. I repotted my Sweet Plum to a bit bigger bonsai pot and with mentioned gravel/peat mix, but the other one (Chinese Elm) is still in its original peat soil from shop. Chinese elm despite having very similar looking peat soil have acceptable drainage. So I decided to experiment with one tree at a time. Any thoughts?

If that is all you have then that is what you have to use, as long as the gravel is small and new not used I would mix about 75$ gravel 25% peat, if the Chinese Elm is draining leave it for now.

My first bonsai book said to mix leaf mold with coarse sand. This was in the 1960s when none of the modern stuff like pumice were available here.

People here grind up pine bark in a food processor for organic water retention and mix that with sand or gravel. One person crushes bricks up. That seems like a lot of work to me.

What is important is that the soil mix your tree is in holds water between watering but drains enough that roots don't rot. How you get that mix is more important than the ingredients you use.?

Can you find any clay based sanitizing grid, pelite or vermiculite locally. All of them is better than non porous rocks.

Some people use kitty litter. That is available in most pet stores but you have to get something that has no deodorants or other chemicals.?

It is very specific kitty litter, not any one will do.

Around here it is not possible to find any non clumping, non parfumed kitty litter made from burned natural clay. But same products is sold as absorbant for sanitizing. That is why I shosed to recomend that instead.
