Hi, my name is Mael. I've had aquariums for about 6 years now. I've had everything from 1 gallon to 55 gallons, fresh and salt water. I breed crayfish and shrimp. I've bred many species but right now I'm focusing on Cambarellus patzcuarensis "orange" (CPO) which is a dwarf, orange crayfish. Anyways, I have this three gallon "Deco-kit" that looks ok, but I want to make it look good. The light and filter on it are good for its current conditions, but I figure that I will need to change them to have proper conditions for plant growth. I also think I will need to get different substrates for the plants. So to start off, I'd like to know specifically what equipment and accessories will I need. My list of things: -Light -Substrate -Filter? -CO2 kit -Driftwood/rocks Please add to my list and make it more specific. For example, I know that I need a light, but what type/brand of fixture, bulb, etc.? Step 2 will be figuring out what I want this tank to look like. I have been looking around the forum and other sites and am starting to get an idea of the layout I want. Thanks for your help! I'm really excited to get this going! Attached are pictures: Edit: I've thought of using one of my ten gallons, or buying a 12 gallon aqua pod to do this. Tell me if this is a better idea.
