As the title says, it's been a while so I'm going to need some help. Tank is a 200L tank, I'm planning to make it a tropical community tank starting with guppies so the kids can get excited about it too. I know that I'll need substrate and lots of plants for it so looking for any and all advice that anyone can give. Saw this video about the broke-as aquarium (which basically reflects my wallet once this is done) and it recommended garden soil, baked to kill off organisms in the soil and then used as substrate with gravel on top. Yes/No anyone? Thanks!
