Low KH (1.25 dKH) - try to grow D. Hairgrass
I live in the Seattle area and I am trying to grow a carpet of Dwarf Hairgrass. Some plants grow well in my tank (Val) and other do not.
I have med tech tank, (dosing PPS Pro, tanked CO2 injection, 80 watts LEDs). 72 Gallon Bow front.
My water is soft. KH in the 1.25 dKH range. My GH test kit is expired and I can not get a reading from it.
I normally do a every other week water change of ~40%, adding some salt and Prime.
Should I be adding some GH / KH boosters as well?
I would like to keep the tank as 'simple' as possible wrt water changes.
