Filter media

Any filter media will help with the Ammonia level, as long as the filter is cycled. That means it's been left in the tank long enough to build up a population of nitrogen cycle bacteria. Thats the best way to handle ammonia in a tank.

Nitrate is best controlled by water changes. You can get filter media to absorb nitrate, but it's a one use thing. Much easier and cheaper just to change larger amounts of water.

All filter media will remove Nitrates in the right situations

All it needs is Anerobic bacteria

Purigen is by far the best I have used in normal instances to remove Nitrates

Or set up a Nitrate filter with a very slow flow rate and it will handle Nitrates

If you have a large tank set up a FBF with Purigen and you will never have a Nitrate problem again

Though this doesnt remove the need for a water change
