Holy crap! I have been using 170ppm TDS water!

[mrhasan]

So got my TDS meter since I was very curious about what TDS water I have been using for the past year. Turns out to be 170ppm! Holy crap! No algae issue or anything till now with this water. My 20 gallon was literally algae free and I used to do 50% weekly water change. My new tank is having diatom on the sand but not sure whether it is contributed by the tapwater or not since my 20 gallon just had an initial bloom and that's it.

Sheer luck or TDS is just over-rated concern.....I wonder.

TING TING TING! Start the debate!
