FrozenFins Posted June 11, 2021 Share Posted June 11, 2021 I have become so fascinating with walstad tanks as of lately. I want to set one up in the near future, and all though this wont be for another month or two I have some questions. Its my understanding that you do 1" - 1.5" layer of soil and then you cap that off with another inch of gravel/ sand, is this correct? Is there anything in the some soils that I should avoid? or will any soil do? I also understand that because its heavily planted the nitrogen cycle is not necessary. I can add the fish the same day I add the plants? But I also heard that you should wait two months before adding the fish to let the aquarium balance out. Whats your opinion on this? And of course in walstad tanks because theres no filtration, Diana Walstad reccemends to have some flow in your aquarium. This would probably help with preventing the bio film that lives on the surface of the water when theres no flow. But then also if something were to go wrong with your plants you have that added source of oxygen. Is this right? Anything else I should know? Its going to be a 5 gallon that will probably house some pumpkin shrimp. I'm also considering ordering the book off amazon because my local library doesn't have it. Thanks guys! 1 Link to comment Share on other sites More sharing options...
