Need help

[JDM213]

need some help everything was doing great until about 3 days ago my pink lemonade started to RTN and was completely gone in 2 days now my tricolor started RTN and my starbursts monti also started to RTN My parameters stays at alk 7.6 cal 420- mag 1440 using a calcium reactor. The only thing that change was my nitrates they were at 5ppm but like I been busy at work I was only feeding my fish once a day I tested today and my nitrates are at 0ppm and my phosphates are around 0.25 could these bee the reason for the RTN? Thanks in advance for the help Tricolor one right you can see how is RTN .
