when i do a part water change iv been told different storys on how long i should wait before i replace it.
iv been told i should let the freash water stand for about an hour, someone else said about 20 mins and then i was told i could put in straight in.
i treat it with a water treatment so it is save for the fish but on waiting for an hour to put the water in it takes a very long time to do water changes.
iv got very confused noe on the best way to do my water changes.
alought i love my fish i dont want to have to wast the best part of 1/2 hrs to cange 20% of the water, any thoughts?
