0.74 is nothing. The max allowed is 4ppm and most are between 1-2ppm chlorine will never be an issue. If you can post the total dissolved solids, CaCo3, magnesium, sulfur, iron or the whole water report I can break it down for you.
If it's chlorine you can bubble it out completely and fairly quick.
If it chloramines you cannot and will need ascorbic acid or water conditioner to break the bonds of the chlorine and ammonium.
Honestly either way unless your using it to bubble tea then I wouldn't even think about it.
