Grey Mantala for false Bottom
I've searched as best I can for a recent answer to this, but just wanted to confirm that if you use Mantala (I'm thinking Grey) as a false bottom, you can just use a barrier screen and then straight to ABG substrate, correct? And is a single layer (1.5 inches) enough, or do you double up?
I'm starting a 24 x 18 x 24 tank and since the lightweight white false bottom (ie from Josh's, or other vendors) seems to no longer be available, I was looking for a low weight alternative. I hand mist and haven't used a drain in previous builds, even in "rainy season" I don't tend to have a large amount of water in the bottom, though I do leave an option for siphoning if needed.
