Dark Moomin Posted March 11, 2009 Share Posted March 11, 2009 I'm guessing its an algae bloom. this will happen when the conditions are ideal for plant growth, which may mean they are not so ideal for your fish. You need to make sure you are reducing nitrates in the tank by changing water, the algae uses Nitrate as food. You could also reduce the amount of light, by hacving the tank lights of for less time. If the tank gets alot of natural sunlight then it might be worth seeing if you can block that a bit. It's nothing particularly to worry about, but it doesn't look the best does it!

testydonkey Posted March 11, 2009 Share Posted March 11, 2009 Think it also depends on how acidic your water is. Also have a look at carbon filters. Hear they are really good Link to comment Share on other sites More sharing options...

jasontsang Posted March 11, 2009 Share Posted March 11, 2009 you need salt water for star fish Link to comment Share on other sites More sharing options...
Bounty2009 Posted March 11, 2009 Share Posted March 11, 2009 Thank you! Is there anthing else I would need to know? I thought it would make a great pet as you can take them out and pet them etc, but low maintainance (unlike a dog)! Link to comment Share on other sites More sharing options...
kateykate Posted March 11, 2009 Share Posted March 11, 2009 Give it a full water change. Once its like that there isnt usually much you can do to make it clear again. Id also recommend getting some otocyncluses(otocyncli??). They eat the algae and are brilliant. Ive had mine for years now and never had any algae probs.

Are you doing regular water changes and I hope you cleaned the filter in water taken from the tank and not under the tap, otherwise the chlorine in tap water kills all the good bacteria you need in your tank. For any fishkeeping questions you can look on the local aquarist societys site http://www.svas.co.uk Link to comment Share on other sites More sharing options...
