my tds after going through the ro/di system is still 30 ish (it starts 200-225). The system is only about 3 months old- time to flush ?

its a coralife system do I need to add another external DI cartridge to get down to zero ?

had my well water tested and came back 3 ppm of nitrite/nitrate will the DI cartridge get rid of nitrites ?

can you buy the stuff to make a back flush kit from hom depot ?

how does it work ? are you basically just pushing the water through the system in reverse?

I'm not sure that you can get all the parts at HD. I just bought a flush kit and there's a new restrictor supplied.
