So I'm using a 5 gallon dwc right. I'm ready for a water change I'm guessing at 2 weeks. So I tested what's in there now and it's still running 5.6 on ph and at 600ppm does it need changed. Will nutrients decrease over time from the plant. Do you just change the water for fresh water. Any help appreciated
Thanks tahcoe
