Comparing TDS readings

[BBQHILLBILLY]

Removed an ugly looking DI filter and bought a handheld TDS hopefully with DI TDS will be around 0

TDS tap 288 and RO 61 with removed bad DI

I only use RO water but try and keep mine under 20. I will let it go if the algae doesnt get bad though. Oh and my tap is always 260-280 range.
