nah kh or gh is water hardness , mainly the kh that's the one to watch
organic solids lower ph and hardness. (rotting plant matter is acidic)

gh just means general hardness but its not too important. kh is the important one really

and yup im a bit of a geek myself. im a sucker for a science paper.
its like an addiction. as long as im filling my head with something I don't care if its nutrinos.
quasars . or bromiliads.

---

bromeliad is only a flower so don't bother googling it. and I know you know what the other two were lol

---

although it is an amazing flower, a tiny frog lives in it at the top of the tree canopy. but that's a whole different story.

---

the flower supllies the frog food water and shelter. the frog provides the flower its waste (fertiliser)
its a symbiotic relationship.
