RO system check

[assafelbaz]

Hi.

How can i check if my RO system is working well? I still have a red slime issue in my tank. (lights been replaced and time been reduced, feeding reduced too)

Thank you.

you can check the tds of the water coming out of the unit. it should be 10 or under

What is TDS?
And which water exit, the filtered water or the trash?

TDS = Total Dissolved Solids
You need to check on the Filtered water.
I would suggest get a TDS meter. Good way to know when to change the filters. My DO/DI unit came with a dual TDS meter.

Mine came without it... I will purchase one.

Thank you all!!!

you can get one for cheap on ebay, and dont forget the calibrating fluid
