Hey guys,
need your advise and clarification on Rowa CR Media as i am still confused by the different terms used...
i) Rowalith C
ii) Rowalith C+
1) What is the difference between these two?
2) To maintain Mg & Ca, which one to choose?
3) Do they have different media size?
I have heard that Rowalith C+ is very effective, but the calcium requirement of my tank is not high, will using C+ overkill??
