Ok so I received my digital TDS meter from amazon today. I measured my 10 gallon tank that I'm getting ready to put some Neos in, and it read 133. I was surprised how low this was so I went and read my other tanks and the tap water. Both of my other tanks read 55 and the tap water came out to 26. Is my meter busted or is it possible I just have really low TDS in my tap? Is this a good thing or a bad thing?
Make sure there's no water current or bubbles near the probes when measuring the TDS. It's not necessarily a bad thing because if you have soft water like that, you can almost treat it like RO. Though before you make any decisions or fool around with your water, make sure your TDS meter is calibrated with a calibration solution.
It's bad if you have shrimp and aren't remineralizing. Such a low TDS means your water is soft and too soft for shrimp I'd imagine. But like others said, it's good in the way that it's almost RO water.

Well the tank that the shrimp will be going into reads 133 TDS so obviously something is remineralizing my water in the tank. That low of TDS is good for crystals and bees, but most neos I see are raised in 200-300 TDS.
