Hi,
Have an established 60ltr well planted tank with an equal number of fast and slow growers and a small number of healthy small fish, the substate is Molar clay with a sand topping.
Been using the APFUK ferts for a couple of years at the suggested level and growth etc is ok, but just prior to the water change the Nitrate level seems high at around 60-80 ppm ( api liquid test kit, tap water virtually 0 nitrate ).
Is this a typical reading for Nitrate using this method of fertilisation or is it too high and we should start halving our dosing ?
