So I rescaped my 20 gallon this weekend. Now I'm having issues..and it's only been two days. Because I'm so bad at describing these things I figure I'll use pictures to say it for me. This is the same tank I wrote about concerning the shrimp in the Invert Section. Am I underdosing (though I don't see how)? Lack of CO2 (even as it appears I may have gassed my shrimp)? The light sits about 10 inches above the tank so that shouldn't be an issue. The bottoms of stems are turning brown beneath the substrate, leaves in general are dying, crypt has holes now and L. arcuata looks as though the color is "peeling" off. It's only been 48 hours!
