What do you mean the Nitrates are fine? I was asking if the nitrates are a good way of measuring the health of the system. If you have lots of nitrates in theory you would lots of fish waste right?Originally Posted by urbanfarmer
Currently I must not be experiencing dentrification because my PH keeps lowering steadily.
Also, I have shell grit in my system. As well as organic free range egg shells. They sit in my particle filter in the gravel from my drive way.
