I have been researching adding peat moss to my filter. Looking to soften up the water a bit, without throwing parameters all over the place. Couldn't find any at the nearest big box hardware store.
I do have spaghnum moss for orchids. From what I can tell, spaghnum is the same as peat, just not as broken down.
Is that correct? Can I use spaghnum moss in my filter? It is 100% moss, no fertilizers or other additives.
