PanW Posted April 19, 2017 Report Share Posted April 19, 2017 Hi shrimpers, how often do you change your water? I've done 10% water changes every other week and still have nitrates problems overtime. I also used active substrate which became more acidic overtime- is it because of the nitrates built up? Quote Link to comment Share on other sites More sharing options...
OMG Aquatics Posted April 19, 2017 Report Share Posted April 19, 2017 If you are not dosing NO3 and your new water contains no NO3, it is because of buildup of waste within the substrate which will create an acidic environment. Do a gravel vacuum or use bacteria supplement designed to decompose of waste such as Seachem Pristine. Quote Link to comment Share on other sites More sharing options...
