DIY external aquarium filter
DIY external filter. This is the final version of my prototype. It works better, and i use it in my aquarium. It's very efficient, and there is apsolutely no danger for water to come out. Water intake is at the bottom. The filtration material is lifted 1 cm from the bottom. Reason for that is: if filtration material is touching water intake, then filth is collecting fast in a small area around intake, and then the water flows slower. The pump is at the top, just benieth the lid. The lid has 2 holes. One for water to go out from the filter, and one for el. wires. To get the wires through the hole, you will need to cut them, and after getting them through bring them back together. Make sure everything is airtight. To make sure it is, use silicone around holes. Hot glue gun won't work. The pump is connected to the hose at the top. Before you turn it on, fill the filter with water. The best way to do it is to put it completely under water when it's open, and then close it. I used a small pump from a house fountain. It says 300 l/h, but I think it's a bit less. The pump is from "Jebao", like this one: www.jebao.com 2 images before puting the filtration material inside: A view inside: img411.imageshack.us Pump at the lid: img169.imageshack.us Feel free to ask any questions
