Why Wall Turn white with Sodium Bicarbonate Options

[white horse T1]

somehow whenever i add sodium bicarbonate to the pail i used to age overnight with anti chlorine/chlormine treament, my tank has traces of white coating the tank wall and even the sponge. but they got dissipated after a day in main tank

why? is it that i put too much or the sodium bicarbonate did not dissolve properly?

During my initial cycle I kept the salinity level at 0.1%. Since you already added and the fish don't behave strangly like ... died. Start diluting when you do water change, as you are changing 20% everyday, by the third or fourth day you would have brought down your salinity level to 0.1%. After that maintain 0.1% against the volume of water change.
