Could someone please recommend a good accurate water testing kit please?
Thanks
Thanks
It really depends on how much money you have to spend, and how happy you are with the scientific method.Could someone please recommend a good accurate water testing kit please? Thanks
Definitely what @Tam says, you can get accurate figures from your water company.I’m initially looking to test my tap water for pH/KH/GH etc so I can work out ratios to mix with RO when I get my new tank going.
That is fine, you can get both dGH and dKH from that.hardness clark
It is a bit strange but both dGH and dKH relate back to an equivalent weight of calcium oxide (CaO) there are links in <"Degrees German">.I had no idea the KH/GH would be the same. I don’t understand why yet, but it very good to know.

The best way figuring out the mixing with RO is a TDS meter/conductivity meter. The individual measures are not as important and in fact, if you try to match KH/GH/pH, your critters may suffer as its the total conductivity they're more sensitive too....So here I saved you lots of money for test kits, time and headaches with my suggestion 🙄

It is really straight forward. It just means that you can use your tap water to add calcium carbonate (dGH/dKH) hardness.Now you’ve really lost me?? I know what it stands for, but that’s about it.
One part tap to nine parts R.O. You can always add salts to the R.O. water, but you can't easily take them away.When you say 1/10 by volume, is that 1 part tap to 10 parts RO?
No, there isn't a direct correlation between conductivity and hardness, all salts will raise conductivity, but not all will raise the hardness.So if I aim for 100microS is that just giving me the correct TDS so I know what my ratio for RO/tap water is? Can I extrapolate my KH/GH from it? By that I mean is there a direct correlation of 100microS to KH/GH?
