I have been using 10-inch water filter housing (also 20-inch) to make filter for my aquarium. The reason I have chosen these housing is:
- Customizable base on your aquarium size and your need. You can start from one then attach more housing together.
- When you have more than one, you can separate different stage of filtration in different housing.
- All the parts and housing are available in most local hardware stores or online.
- Clear 10-inch standard water filter housing (Slim type can also be used, it just a little thin)
- ¾” PVC Pipe, couplings, elbow and one or two dual union Ball Valve (is optional for quick disconnection of hoses attached to filter)
- Water pump of your choice
