Re: EI and ADA substrate
What Alex said.
I have the same beef's.
So many folks rattle on about how great it is, well, in some respects, but the two layer approach has trade offs and I don't like the low density, goes flying all over. Takes longer to do the pruning.........
Add the white sand front and any terracing over the long term........you know what is going to happen and folks can say whatever they want, we all know it's going to mix.
