I am working on my dissertation but have not been able to procure funding yet. As a result, I am taking a different approach to equipment. I am looking for aquariums of all sizes to house various strains of algae, invertebrates and vertebrates for toxicity research and carbon dioxide trapping. I am looking for aquariums that hold water (or can be easily fixed). Size is not a huge issue but I dont really need anything of the 75+ gallon variety. So 5+ is good. I dont have a lot of money so I am looking for tanks people are looking to get rid of or sell cheaply. Please let me know what you have and what you are looking to get. I can also use any old pumps, power filters or various and sundry supplies. Thanks
