I have started my first soil based planted tank and am also attempting the dry start method. I am using common topsoil that I mineralized via the Aaron Talbot method then topped the soil with Estes black aquarium gravel. I have planted only foreground / carpeting plants as follows: dwarf hairgrass, marsilea quad, styrogyne repens and a few moss types. Once planted I did not fill the tank but misted until I saw puddles - I only have one small puddle left. At first I used my hinged glass lid and allowed an air exchange via the rear open area of the lid but have since been advised to cover the top with plastic wrap. I have completely removed the hinged glass lid and covered the tank top with 2 pieces of 18" wide commercial plastic wrap. I also open a small area of one corner during the day for air exchange and completely enclose the top at night. I now only mist the tank when it appears dry. All of the plants appear to have turned from green to brown, which I believe I should not be concerned about but now some of the plants have turned white like cotton or spider web-like - what does that mean and am I doing something wrong? Is this just part of the DSM process?
Thanks for any and all tips, advice or information.
