You should use more akadama and mix that with your molor clay.
Its what you will find most on here put in there mix for deciduous trees mix 2 or 3 parts akadama with one part molar or use boons mix just add an extra akadama part.
Yeah everyone uses it.. I'm just not so convinced it's the only way of doing things. Plenty get by without.
Our Tesco cat litter is supposed to be the equivalent of akadama, according the bonsai4me and recommendations. That's why I'm using it . Although I'm told you can use 100% inorganic, I learnt quickly after repotting that'd be useful to have parts organic, dependant on the preference of the species.
But one thing for sure and that I agree on, my mix will change next time round
