Thinking about getting some sand for my 90 geo tank but I don't want the fine sand that blows everywhere. When it comes to mesh size, the higher the number the larger the grain or opposite? Not to much clarity from Google

If you are looking at specifically garnet sand, the smaller the number the larger the grain. So 40-80 mesh is somewhat finer (getting closer to powder, usually 100+ is like powder). So ideally, you'd want something under 40 mesh.
I just bought some garnet sand that is listed as 30-60 grit, 50 pounds for $30 Canadian (currently about $22US) at a discount tool place called Princess Auto. Two bags on separate occasions, one was slightly less red than yours and one with very little red at all. Mixed 100 pounds into the 250+ pounds of pool filter sand already in the tank and it darkened/coloured the substrate very nicely.
Maybe not the perfect choice if the reddish colour is the goal, but...at 75% lower price... It's a very dense, heavy sand that doesn't stir up into the water column.
