I'm just figuring out GH & KH and could use some direction.
With the API Test Kit I have a KH of 5 and GH of 25. Which, if I'm right, means I have super hard water.
What does that mean for keeping fish? I believe it means shrimp are out of the question.
I have fish now that are fine, but going forward do I need to adjust it at all? Use distilled or RO water? How would either of those affect my KG? How would a water softener (for the whole house) affect fish keeping?
Generally, what do I need to know or do any this high GH?
TIA
