Along the lines of 'making sure it's plugged in'...Remember that vals need to be planted with their crowns not buried in the gravel. If the crowns are buried it will kill the plant. BTW, vals love hard water, that shouldn't be a problem.

That's something people often overlook, even though it's the most important factor when keeping Vals. You should plant it so that 2/3rds of the crown is visible.
