Get your tds to 0 first

RODI should be at zero. Somethings not right.

I used color changing resin to refill .I packed it kinda of tight maybe to tight .The color hasn't changed at all and the water came out zero at first but then after I made 24 gallons it was up to 3 tds already .

I’m wondering if the o ring on your ro membrane is seated properly. I hate ro issues. If you have a backflush is the valve open by mistake? Good luck.

I doubt the ro/di is pushing up calcium. 540 ppm is fine and I’d ignore it.

it would be good for other reasons to get the ro/di to 0 ppm tds.

Thank you I changed di resin.It is back to zero .What is a to high calcium level ? I thought with high calcium you get a lower dkh .
