today I'm building an indoor koi tank. It will be a fully functioning tank and filtration system where small koi or other fish can be temporarily quarantined. The system will consist of the following materials. For a basin, I’m reusing this 700 liter food-grade pallet box. This 90 liter large concrete mixing tub will serve as a pre-filter and sedimentation tank to filter out the coarse dirt. There are also various small parts that will be used, like this wall bushing and a suitable sealant compound. With this and the pipes, the whole system will be connected to each other. Then we have this ball valve as well as High Temperature pipes and PVC pipes. These brushes will later be installed in the mixing tub. I didn’t want to build a filter with any sponges because they clog up immediately and have to be cleaned often. Therefore, I bought these brushes that are 15cm and 10cm in diameter, and we’ll see how we make them fit into the tub later. And then we have this rain barrel, which I want to utilize as a biofilter with Hel-x Biomedia. This basic pump that runs 2000 liters per hour will provide the necessary circulation. These are the main components at a glance and I'm looking forward to the assembly and the end result. The unique thing is that the filter system will work as a gravity system. The water surface in all three connected tanks is at the same height and the pump simply creates the circulation from one spot. This saves energy in contrast to pumped filter systems and the functionality has been proven. But one thing after the other, then the structure will be clear. First we’ll begin with the construction of the brush filter from the rectangular 90 liter mixing tub. The water should run straight through the tub and the floating particles should settle at the bottom and on the brushes. To achieve that affect, these 75 mm wall bushings are installed at the front and rear of the tub. These are installed with the included stainless steel screws. I put the flange piece on the outside and mark the opening. With a 10 mm hole, I can then easily use the jigsaw to cut it out. Use a file to clean up the cut edge. Then I insert a 75 mm pipe through the opening, and it fits. Now the flange piece can be placed in the center and I can drill the holes to fit exactly. Next, I roughen the surfaces with sandpaper, so that the sealant has good contact with the components. All the surfaces should be smoot . I wipe off the dust and then use Aquaforte’s Superstrong Fix & Seal. This can be easily applied with a silicone press. I apply an outer and inner ring on the surfaces of the wall bushing. I start with the flange from the inside and align it with two screws. I press some of the sealing compound into the screw holes so that they are waterproof afterwards, but I’m not really sure if that’s necessary. I turn the two screws so far in that they protrude out the other end. Then the outer flange can be aligned quite well and I can start putting the rest of the screws.
