Hi guys,

TDS reading for my tap water is 41 PPM
TDS reading for my FW planted tank is 81 PPM

The number 81 means I need to do a water change for my planted tank?
I'm not sure what the number represents, what number is good or bad.. no idea.

I am going to set up my R.O unit and test for TDS, wondering what number will turn out.

So do you guys know the PPM of your reef tank water?

BTW, I got my Remora skimmer 1200 and that thing is a bit of loud..
Hopefully the noise get better after the break in period.
