Firstly accept my appologies for asking yet another question about high nitrates, I've asked a few I know!
The nitrates in my tap water occur at 40ppm as we are a very agricultural area, so before I even start my nitrates are high let alone what my fishes add to it. I have been researching Purigen as a method to lower the nitrate level, what do you think and PLEASE PLEASE PLEASE don't say water change or I might scream, I know this is how to lower nitrates but when your tap water starts off at 40ppm this makes no difference to your tank when without the natural level they only increase by another 10ppm.
In theory if the purigen can remove the nitrates in my tap water the only thing I'm battling then is the nitrates my fish produce at 10ppm which I can control with water changes.
Or, does anyone have any other suggestions?
