After over a year with my salt tank I decided last weekend to take it down and convert it to fresh water. When i started it i bought some LR from some one who took their tank down. It had lost all its growth. When i took it out the bottom of all the LR was dark purple. I had actually been doing somthing right! to bad it wont do me any good now.
just thought i would share.
