How do you raise KH. It is always around 6, even after water changes. Other levels:
PH 8.2
Calcium 360
Nitrate 0
Ites 0 (last time was checked) don't have test kit for that
Phos 0
KH 6
46 gallon 2 months old. everything knock on wood looking good.
water hardness(kh) is depleted over time, a couple small water changes should help..
what water are you using?
I have been doing water changes and it does not help. I use R/O and tropic marin salt.
Kalkwasser is only to maintain your levels.......You can buffer with Calcium and a Alk buffer to get you to your levels and then use kalk to maintain......Same thing with a Ca reactor......they won't raise you to your levels they maintain them....
With those levels I would say you are using IO salt. Switch to IO Reef Crystal and through watter changes, as long as you don't have a large load, your levels will come up.
