Either way, I'd still be putting a fertilizer tab under each plants root
ball. You can make a circular hole in your current substrate too, put in
a fertilizer ball, cover with fine gravel, plant your plant and then top
up with your normal gravel and you'll never know it's there This way
the fertilizer nutrients will leech along the bottom of the tank,
providing fertilization for anything in the substrate.

I do basically the same thing for my outdoor plants. How long do the
fertilizer tabs last?

The ones I use (JBL - Germany) last 12 months. They disintegrate over this
time period. They are the longest lasting I have come across in Oz. They
sell "Dino-Dung" locally made, but it only lasts 6 months in potency and
structure.

I think the average ball lasts about 6 to 8 months - Seachem etc...
