Ah, of course!
Am so glad I asked for opinions, I actually did not think of this and it seems very obvious now.
That probably saved me a ton of trouble if I went ahead and mixed the senegal sand, which is larger and coarser than the sansibar sand therefore ending up with a concrete like locking of substrate.

Excellent, will have to pop into my local M.A and see if they're selling these Unipac bags cheaper as you say. Thanks
