How do i lower them?

a PO4 binder like RowaPhos... as for NO3.. there are some sponges out there, I don't use them.. I do a 10%15% water change every week, it keeps them down for the most part.. a protein skimmer helps a lot also, it removes fish waste from the water before they can turn into NO3....
do you have high levels or are you just wondering?
