Tropical Fish - Green Water

Hi there and welcome to another quick tip regarding caring for your tropical fish.

What to do about green water

Well that’s a great question for a common problem most tropical fish lovers will face.

If the water in your tank is green, cloudy, and murky, then you have ‘green water’.

This is a particular form of free-floating algae which hangs suspended in the water, giving it that characteristic opacity – in some cases, the water becomes so green that the fish are obscured.

It’s usually due to a significant excess of light (usually sunlight, as opposed to too much fluorescent), or a problem with your water quality.

To treat this problem:
  • Block all sunlight from reaching your tank for several days to one week. You can do this by draping fabric over your tank, or making sure that all the curtains remain drawn in the room where your aquarium is placed.

This is very effective.

  • Keep your filter mesh as fine as you can: most generic filters come with pretty coarse mesh, so replace it with a fine-meshed sponge or use a diatomic filter (designed specifically to treat algal problems). Remember to check the filter regularly, or else it’ll get clogged.

General algae prevention tips for you.

Regular maintenance of your tank is one of the best preventative measures when it comes to algae:

  • Change the water regularly

  • Clean the aquarium regularly

  • Use a UV filter in the tank

  • Situate the tank away from direct sunlight

  • Don’t overcrowd the fish

  • Keep the food levels down

  • Minimize aeration unless your aquarium is very well stocked: keep airstones and vents to a minimum

  • Utilize your plants’ nitrate and phosphate absorbing capacity: stock your aquarium with plenty of fast-growing species like Ambulia and Egeria.
