Hi all,
I've not studied chemistry for some time and have not a great knowledge of TDS.
How does TDS compare as an indicator of suitable water vs the hardness of the water.
I have just invested in a TDS meter today and have tapwater with a TDS of 60ppm, but the water in my tanks was around 680, 420 and 320 ppm. The tank with 680 has wild A. panduro spawning in it and a KH of approx 1degree when taken with a JBL test kit and pH 5. The nitrites and ammonia are zero, and the nitrates are around 5ppm max. The phosphates are high however (I think due to the breakdown of so much leaf litter). So, I guess my question is, is it to do with the actual total ionic concentration (if that's the right word) of the solution, or is it more the concentration of particular ions in the water that matters?
