Re: To add or not to add extra Iron to CSM+B

Nevermore,
do you know your tap water parameters? Do you keep everything consistent? Any all house softeners? How high is your NO3 and PO4 if you don't change water?

Re: To add or not to add extra Iron to CSM+B

Nevermore,
the first thing to glow here is the amount of PO4, where is the 2 ppm coming from? What is the fish load to plant mass ratio? Is the PO4 coming from fish food or substrate? Is your tap PO4 undetectable by the same test kit as the kit you use for the aquarium? You need to find how much of Ca is in your tap. What KH?
