I am looking for an overview and opinions on the importance of hardness (GH
) when it comes to planted tanks.
What is the perfect level I should strive for and how do I keep it there once it is achieved?
My tap has varied from a GH
I also have this:
but after using it last night, I think maybe my cartridge is bad or something for the layers were separating and a few green pieces were going into the bucket.
I have 3 tanks planted right now with the following GH
20 tall - 8
30 long - 18 before last nights 50% water change with previously mentioned RO
150 breeder - 25 (I know way to high and not sure why?) It has 2 large peices of driftwood and a bunch of granite w/ one questionable metallic rock that I am taking out tomorrow.
I have sort of been lazy with my caring for GH
for several months now.
What level should I be shooting for and why and how?
