I purchased some DHG for my 72 gallon fish tank about 2 weeks ago now and it turned yellow on me and many patches died. Did any of yours turn yellow or die on you when you planted them or added the water? Not sure if it is the lighting or what. Haven't had any algee growth either which either means I'm great at setting up tanks or I screwed something up and even it can't grow. Thanks. And your tank looks great! Hoping to have bountiful DHG carpet like yours one day.
