johnsmith Posted October 10, 2006 Report Share Posted October 10, 2006 Will this stuff grow with just room lighting ~ 8 hrs/day Quote Link to comment Share on other sites More sharing options...
jvision Posted October 10, 2006 Report Share Posted October 10, 2006 It'll probably grow, albeit slowly. This stuff does great w. normal tank lighting. Quote Link to comment Share on other sites More sharing options...
johnsmith Posted October 11, 2006 Author Report Share Posted October 11, 2006 Okay, another question. I know this stuff spreads like crazy so what happens if I put some in a 10g and never take any out? Quote Link to comment Share on other sites More sharing options...
jvision Posted October 11, 2006 Report Share Posted October 11, 2006 I've had it about 3" thick before I thinned it. It basically, just builds up on itself - the bottom stuff will probably start dying off b/c of lack of light, eventually. Quote Link to comment Share on other sites More sharing options...

JHG Posted February 10, 2007 Report Share Posted February 10, 2007 I had a single "harmless" duckweed <1cm plant that hitchiked along with a Corydoras purchase. Here's what the tank surface looks like 2 months later. Quote Link to comment Share on other sites More sharing options...
jvision Posted February 10, 2007 Report Share Posted February 10, 2007 I thought I got rid of all duckweed in my 90 gal - only Salvinia. This morning, it looked just like that! :grr: Quote Link to comment Share on other sites More sharing options...
