This will be my fourth set up tank and the first time I deal with invertebrates. My wife has been talking about how cute they are and I wanted to do something special for our anniversary. It's a 20gal tank. I have the black gravel and the different types of plants and everything that I wanted in it. I know how to cycle and I have a master testing kit. My main concern was filter and lighting. All the plants inside the tank will be live. I also need a website to buy the shrimp from as amazon is kind of pricey. I do have an HOB 20-40 gallon filter that I thought I could just place panty hose over the intake valve. But any thoughts or ideas from you guys personally would be great. Do I need to purchase api CO2 booster?
