Following on from my previous post, the remaining 8 plants are beginning to go black and some leaves appear as though they are being eaten but there are no fish in the tank. Also, there is a whitish substance/mist across part of floor of the aquarium. Incidentally, I purchased the plants from Pets at Home approximately 3-5 days ago, costing £30. What are my statutory rights where aquarium plants are concerned because it looks like I'm going to have to drain the tank, give everything a good clean and start the cycling process again? Stupidly I didn't do any research with regards to live plants!
