Hi All.
I am upgrading from a 60 litre to a 180 litre this week and I want to do a
cycle with my old filter running along side the new one.
Now what I need to know is while I am doing the change over I am going
to leave a third of the water in the old tank and leave the filter lying on
the gravel,now does the filter need to be kept running to preserve the bateria
or can I just leave it submerged for a couple of hours.
regards tony.
