Sera plantrit + coralsand?

[Slan]

Hi every one.

Yesterday I bought a bucet of Sera Plantrit, I should mix this with some sand I guess?

Would coralsand be good ? i mean maybe there´s things like calcium and kalk in there which is good ? I have other kinds of sand to, but i´m thinking coralsand may fill up some needs to in there. just guessing.

Have a good day, and night.
Greetings. Simon

Coral Sand will increase your Hardness and pH and later you will have problems lowering the values.
