what i ment realy is how long for the prime to work before filter goes on?
Sorry miss understood, almost instant couple seconds. Bit like mising ice tea as an example
Yeah it acts pretty fast. I have the filter off while I do it then add the dechlor gradually with the water coming through the hose (with the temperature roughly matched to the tank via mixer tap) and once it's full I have the power head running for a bit to ensure the dechlor gets well circulated before putting the filter back on. About half an hour to an hour.
thanks i was dredding my first water change in the rio lol.....
