Chiak lat lah,

I have been using about 12 table spoon for a 4 ft tank (full ).
In the last 3 months I must have used more than I kg of salt per week ( 2 tank 50% water change every day ), so, maybe in total more than 20 kilo lah........
Sundry shop boss wondering why?.........
.........eat salt more than eat rice?............

Cheers!
