JohnRosario Posted August 25, 2010 Report Share Posted August 25, 2010 Hi Guys I have noticed my planted fresh water tank has been developing a lot of protein strands on the surface of the water. Any ideas on what is causing this? Quote Link to comment Share on other sites More sharing options...
jvision Posted August 25, 2010 Report Share Posted August 25, 2010 What's your CO2 situation - DIY or pressurised? I notice it more often on DIY systems. Also, the quality and quantity of food can play a roll - even with great quality food, if you're feeding too much, you'll see that scum. The other option is that it could be algae - typical causes are poor circulation, low CO2 and low NO3. Quote Link to comment Share on other sites More sharing options...
