The water change to green

[danielma]

Dear all,
Recently I have some problems on my water.The color of my salt water changes from colorless to slightly green.The only things I have done are change the brand of the salt from Crystal Sea to AB and start to feed Tetra Bits to the fishes.I've checked the lighting is no problem.No tank position has been changed and no direct sunlight.What do you think about the root cause of the change.

Not familiar with those salt mixes but some cheap salts are made from evaporated sea water. This means you get all the nasties/algaes that have died in this process. This could be the cause as all else appears unchanged.

I too would have to agree with this theory.
