Hi. I’m new here and I’m a noob when it comes to fish. I just started my hobby. I’ve got a 60cm x 30cm x 30cm tank. It’s about a week old now but its becoming very greenish the water. I read on another site that it’s because it’s a new setup and that the balances are not right yet but that it would get better in a few days and that this will not harm my fish. Is this true and can anyone maybe give me any advise? (thanks for moving the post)
