You will be happy with it, try and keep water change water relatively close to the buffered water from the substrate (pH wise). How long are you planning on running this tank? That substrate turns into black muck starting at about a year old. I would also invest in some root tabs, they drastically helped my plants when i used the fluval stuff even tho they classify it as a planted/shrimp substrate. Overall you should like it, easy to plant in, looks nice and keeps a stable pH.
I'll keep that in mind in around the year mark. I plan to have this tank for that long at least. No sure how I'll buffer the water changes though.
