Di resin bed

[Will]

Is it worth the price difference to purchase Nuclear Grade Resin. Or should I just go with standard?

I tested my tds today and is at 6ppm. Water supply is at 435. How could this be after only 3 months of 10 percent weekly water changes along with top offs?

A water supply of 435 is why. In the Seattle area our incoming supply is under 50 and most reefers replace their filters at least once a year
