How do I get my fish tank water crystal clear?
A good, short term way to get crystal clear aquarium water is to use a flocculant. Flocculants clear water by clumping tiny particles together, making bigger particles, which can then be removed effectively by filtration.
How long does it take a cloudy aquarium to clear?
During this process, beneficial bacteria build up in order to consume the ammonia being produced, hence causing the water to be milky. This cloudiness is caused by free floating beneficial bacteria which are not harmful for your fishes, and should go away when they settle down – usually takes about 1-2 days.
