Q: Hi! I bought a 16l tank yesterday at Qianhu, and had treated the water with the Ocean Free Water Guard and Ocean Free Bacteria Battle 8000 before putting in the fish as advised by the shop. May I know to cycle the water, how often should I change water and how much of each of the water guard and bacteria battle should I add? E.g. how many ml of each for how much liters of water. Thanks.
A: Hello David,
For the first two weeks, you should change your water around 1/3 of the tank water once every 3 days, then subsequently change to it once every week. Lastly, add in the water guard and bacteria battle accordingly to the manufacturer’s instructions.
