Hi MGilchrist and Andrew,
thanks for the replies !
just done another water test, results :
ph 6.6
ammonia 0 ppm
nitrite 0 ppm
gh 3
kh 1
have had a water softener in for 48 hrs as last week gh was 8 and kh was 2
I only have plants ( Vallisneria, Blue Hygro and Hair grass lookalike ) gravel and rocks. No peat. Using tapwater with water ager and cycle at each water change. I change between 20 and 30 %
Is my kh too low? How do you increase kh ?
thanks again,
Robbo
