Hello, I just started a nano tank with three male guppies. It is aquascaped with just seiryu stones. I have aqua complete soil (which I hate, but that is another topic) and it is planted. I do not have CO2. My tank cycled and I've been sitting at a pH of 8 with GH and KH of 6.
I read the blog about guppies, and realized I needed to raise my GH and KH. I added one small wonder shell, an almond leaf, and the guppies all at the same time. My pH has not changed nor has my KH, but my GH went up to 9. Small victory!
When I was at my LFS, they looked at me like I was crazy: there was no way I could have a high pH with low hardness. They wouldn't sell me anything.
What are your thoughts? Do I need to get the KH up for guppies, or should I not worry about it? Is there something that can help the tank?
