Bag Filter holder 1.0

So, since I've upgraded to a larger aquarium now, my little filter bubblers isn't getting the job done anymore. I wanted to go big-time! But I quickly realized that a filter bag was the way to go for me - and I'm glad I did because I had trouble finding them locally, and it was impossible to find any mounting options at all. So I decided to take matters into my own hands and make my own! Size: This adapter is designed for bags with a 100 mm diameter. The inlet port accepts 1 cm hoses and is tapered to fit slightly larger ones too. I used a 20% infill, which should be enough to keep the shells waterproof on their own - but I added an extra 20% to make it nice and sturdy. How to use: Just slide the ring up to the flange of the bag, making sure it fits your filter. Some filters might vary in size even though they're specified as one size - trust me, I've learned that the hard way! Place the cone part on top of the ring and secure them together with zip ties in the four clasps. This creates a pretty decent seal all by itself. Connect it to a pump using a 10 mm hose and you're good to go! Recommendations: I use a pump with high flow but poor static pressure, which works just fine for me. I've tried 100 and 200 micron bags, but even the 200 micron bags get clogged quickly - so try to find something with bigger holes. I'm currently working on a design that incorporates filter wadding inside the bags for stage filtration, but it's still in beta testing. This setup works for about a week before you need to wash the filter, but it's worth it because it removes an astonishing amount of debris.
