Coral sand is likely to increase hardness that may not be wanted depending on fishes you plan to keep in the tank.

River sand is awesome, if you can collect your own, you can get rougher grain sand by being selective of the area you dig it up from.
But even the finer stuff has fairly little dust in. It gives me so much pleasure watching my sandfish forage in the sand from the river they come from. The cory's and pleco's also seem to enjoy it.

Thank you for helping me

I would assume that all rivers are different so the sand will also be different? Depends on what rocks are eroded and broken down to form the sand.
So the problem with coral sand is just the PH right?

I'd imagine it to be very high in salt too.

Coral "sand" is a natural buffer that keeps pH around 8+. This is what marine environments need. You cannot use it for a planted tank.
So i will take river sand...and thank you for helping
