Hello all
I have a new question wich i willtry to explain in english
I have a CO2 injection system for my wellplanted tank.
It's secured with e pH detectionsystem, so when the pH is to low, no more CO2 is injected.
now,
the kH in the tank(carbonate hardness) is nearly 0. wich brings the pH around 6.10
this is ofc under te minimum limit for pH injection. so to CO2 concentration is very low, wich
ain't good with that many plants in the tank.
now the question:
the water i use to clean the tank has a kH of 4-5, wich is perfect.
when I raizes the kH of the tank to 4.5, i thought i could maintain that lvl of KH with refeshing 15% every week
with fresh water with 4-5kH aswell
but somehow, the kH drops to nearly 0.
howcomes?
what sucks this away?
I have some wood in it, JBL filter, no uv or other devices.
plants and fish... no stones, juist one porous (i hope this is a good translation lol) thingy in stone.
anyone got any idea?
thanks in advance
grtz
