It's hard for me to find a balance...I have sps dominant, but love softies as well...haven't found that magic number yet...I've never had phospate show on any my tests, even try to over feed but still stuck at zero...guess that's the reason I'm getting burnt tips and some stn..
Is it burnt tips or new growth? Yeah softies in my experience don't do well they like dirtier tanks my blue Xenia and palua nepthia has stayed frag size for almost 2 years.
