Light and water hardness
I read a write up of an aquarist that moved from a location with soft tap water to a location with hard tap water. This individual used the same set up, plants, fish, dosing, CO2 fertilization, lights, etcetera but could not get as good growth from the plants.
This person stated that they had to increase the lighting to make up in part the growth they had in softer water.
I have very hard water. 8.5 from carbonates mainly. Some bicarbonates.
Has anyone come across any information or studies by Tom about light levels and water hardness?
I didn't claw my way to the top of the food chain to eat vegetables.
