Hi
I have a 240L planted tank.
I would describe the planting as medium to high.
I think for the size of the tank the fish stock is low.
I have CO 2.
An external Oase 850 filter.
The tank has been running for almost 1 year.
I have been testing the water with the API freshwater test kit.
Apart from the Nitrate all the other tests are very good.
Over the past couple of months the Nitrate has been going steadily upwards 80+
I have been doing water changes of 25% twice a week.
The filters are are closely monitored .
After all this the Nitrate does not improve.
I now have Pro JBL Aqua test.
The Nitrate reading is between 15 and 30.
Clearly this is a huge difference.
Point is which do I go with.
The fish appear happy enough. I would have expected some to be killed off at the higher reading.
Hope someone can pass on some ideas.
Just to add the API has an expiry in 2005.
