Aquariums: Anyone have experience with KH of 2, is it easily manageable ?
Tank is for German blue rams
29c
Ph – 6.8
GH 4-5
KH 2-3
I’m doing 50/50 tap water with RO water

Yeah it’s easy if you have inert substrate and things that don’t affect water parameters

Yes it’s perfect.
Beginners will tell you to increase it with no good reason, but generally a lower KH is better especially for softer water species. 2 is good 0 is better.

at 2 you have very low buffer of pH in the tank. if you have a number of plants, you could expect swings of 0.5pH through a 24hr period as it removes and adds co2 through day and night cycle.
kh does naturally get used up in waste from critters, nitrogen cycle and if injecting co2 for plants so will need monitoring regularly as less means more unstable swings are possible.
if you add things with tannins and botanicals like plant leaves, be careful as they will have a strong effect on pH compared to a higher kH.
