I have switched to from Aquasoil to Flourite about a year ago, at the beginning, I kept my Toninas in a small pot with ADA Aquasoil just in case, at the same time, I planted a few stems in Flourite for experiement. The differences I found was minimal, the ones planted in Aquasoil are a little smaller and that's all. The tank parameter back then was KH = 2, GH < 1, and pH 6.4.
Now I am planting all my toninas in Flourite, and in recent 6 months, the water parameters have been changed, to KH =5.5, GH =4; the thing is my toninas are still thriving.
I have been planting Toninas for years, admittedly it does best with Aquasoil, but the most important factor is extremely high light, acidic water and penty of CO2.
Hope this helps.
