Fertilizing with RCS
I have a 10 gallon with RCS (and Endlers). It is medium planted. Black sand substrate. No CO2.
I plan on using Excel and dry ferts.
Since the dry fert quantities are so small, can I dose once a week after my 25% WC?
I was thinking (once a week)
KNO3 1/4 tsp
KHP4 1/8 tsp
CSM+B 1/8 tsp
What do you think?
