the mere thought of you wanting to place your fish directly into a tank which was just filled with water from the faucet is representative of the type of keeper you are... Dili na gani ka kahuwat pa ugmaan ang tubig para mabahaw to get rid of chlorine, how much more when you do water changes... Luoy lang ko sa mga isda nga imong i-keep puhon...
Therefore my advice is to go with davecobain's suggestion, "pagbuhi nalang og nguyo2x"... ayaw lang nang isda...
