Fluorite substrate questions

[valen1014]

For those who use fluorite sand, do you have problems with airpockets? do you use root tabs to supplement root feeders?

I've never used fluorite, but I was told it's better to just use playsand and a liquid fertilizer. I have root tabs but I don't use them (I dig around a lot and when you dig one up it makes a huge mess).
