SuperGuppyGirl Posted November 24, 2014 Report Share Posted November 24, 2014 So have a set up of 3G, with an airstone, hunk of wood with Java Fern attached on a thin sand substrate, how do you clean up your daphnia culture tanks without losing half your culture? Just been adding aged aquarium water to top off but this looks gross. Quote Link to comment Share on other sites More sharing options...
Jayba Posted November 24, 2014 Report Share Posted November 24, 2014 Steps - Divide the tank in half with a black piece of Plexiglas with a 1 inch hole in it.(sonewhere around center) - vacuum clean the side that won't be the blacked out side. Then net out daphnia - Black out the one side of the tank 3 sides plus the top - place bright light over non blacked out side. The daphnia are attracted to the light. Then vacuum the blacked out side and remove the center divider. Done Quote Link to comment Share on other sites More sharing options...
SuperGuppyGirl Posted November 24, 2014 Author Report Share Posted November 24, 2014 Excellent! I've been googling but the nylon over tube defeats the purpose, thanks jay! Quote Link to comment Share on other sites More sharing options...
SuperShawn Posted November 24, 2014 Report Share Posted November 24, 2014 I have 2 20 gallon tall tanks that I use for daphnia. I use the light method as well, when the daphnia swim to the top I can vacuum the bottom. Quote Link to comment Share on other sites More sharing options...
ckmullin Posted November 24, 2014 Report Share Posted November 24, 2014 This light method works great for brine shrimp as well. The preferred method I use. Quote Link to comment Share on other sites More sharing options...
