Tank Gone Pink

[Dana C]

I used some interpet flora boost fertilizer in my tank on saturday and it turned my water bright red, the water has now cleared alot but my sand has gone a pink colour.
Will it stay like this?

Does anybody know a better fertilizer to use?

Thanks for any comments.

Correct me if I'm wrong, but the fertilizer you used is for ponds.

I use Seachem.

Others use different.

Thanks for your reply,
It did say for aquariums on the bottle but I don't think I will use it again as my sand is still pink, I will try the one you use instead.
Hopefully the pink will just fade away on its own.
