tamboy Posted February 13, 2010 Report Share Posted February 13, 2010 Hi Try using an API product called AlgaeFix I have used this sucessfully on Green water problems, which tend to be little more difficult to slove than Green sides on your fish tank Should be readily available from LFS for about $11-12 for small 37ml bottle Good luck Quote Link to comment Share on other sites More sharing options...
stillnzcookie Posted February 13, 2010 Report Share Posted February 13, 2010 We solved this in a 60L tropical tank by doing a big water change, then a 3 day blackout, then another big water change. It could be caused by overfeeding or sunlight hitting the tank (even a tiny bit of sunlight directly on the glass can turn water into pea soup, as we discovered). You can use algae-rid products, but if you don't find out what is causing it in the first place, it will just keep coming back. What temperature is the water at this time of year? I don't know anything about coldwater fish-keeping, but I wonder if a higher temperature could be encouraging algae growth? Quote Link to comment Share on other sites More sharing options...
