Thanks again for your reply!

API master kit says Nitrate of tap water is zero, tank Nitrate has come down a little to just above 20.

Does the flow rate impact at all how well the biological filter deals with nitrates? I had set the pump to the highest flow rate (600l/hr) to generate more oxygen. Having looked online at Ex-Nitrate by Seachem, it says the flow rate should be no more than 200l/hr for this product to work. Is this the reasoning behind it?

Will do 10% water changes for now!
