Does 0 TDS is good for SPS tank?

Hi everyone,

Just moving establishing SPS tank instead of my LPS tank.
Now my RO system tke water after 15 min work as low as 7TDS an sometimes 4TDS but after 15 min work at least.

Should I put another steps to RO system with resin media and go to 0 TDS?

Thank you.

Yes, I would get another piece that allows you to add DI to your RO system.
Almost everyone here does to help remove any left over phosphate for example that the
RO misses.
