Dealing with Chlorine and Chloramine in Water

[Ralph]

@Nicknjh23

The Kh hardness of water keeps it stable, the lower this is the more liable water is to swing. I used to keep Discus tropical fish many years ago. All I know is that if I didn’t re mineralise the RO water and just store it the Ph would tumble.

Sure, I don’t doubt it for keeping a fish tank! But it’s a different application and the water’s being kept/stored in different circumstances as mentioned above.

@Nicknjh23

If there is nothing in the RO water. Then trace elements aren’t available to the plants

Again, I suspect rainwater is very low in these too (?), not as much as RO perhaps, but still cause for occasional additive or use of ferts with micronutrients.

@Nicknjh23

All I can say is having water at ph 6.5 amd a TDS of around 100-120 will be perfectly acceptable for Bonsai cultivation

If a lower TDS is acceptable too, then that’s much simpler in my case. Cheers anyway for the input
