How do I purposely raise phosphates in my tank just a little? I took out the phosphate remover 3 weeks ago after learning that my nitrate reactor's bio pellets actually need some phosphate to grow nitrate removing bacteria. My Salifert test kit expires in Oct. 2020 but reads 0 phosphates and nitrates still climb quickly even after water changes and less food being fed to fish. Has anyone used Brightwell's NeoPhos with any success? Any suggestions would help.
