I've seen this recommended for bettas. Anyone use it?
My ph is naturally high and I don't chemically alter it, and the water is hard.
Blackwater extract would seem to be a good way to naturally lower the ph and soften the water a bit. It would, of course, run counter to the idea of getting an Apple snail. However, from what I've read the two can certainly coexist, but the conditions would be at best a compromise for both and at worst ideal for one and barely adequate for the other.
Considering the issues I've had with this tank, I'm now leaning toward it being Betta only.
