Tap Water Question

[LizStreithorst]

You have perfect water. As has been said before, you just need to change more water and the pH will remain stable.

I'm not sure what your question means but,the TDS will increase with time just like your nitrates do.That's why the WC's for more stability.

Got an HM meter off of Amazon. Tap Water has a TDS of 31. Checked the main tank and it is 57. That's after a 50%WC yesterday.

If you want to compare the TDS of tap and tank water, you should warm up the tap water sample so its close to the temperature of the tank. Otherwise you aren't getting an accurate comparison. Some meters don't have temp compensation (like the HM TDS-EZ) and some do (like the HM TDS-3) but even the ones that do compensate are making an estimation.

Thanks guys. Consider me informed.
