Aquarium with filling 3. Filter from scrap materials

Hello everyone! I will continue the aquarium theme. Previous: Filled aquarium and Filled Aquarium 2 .
Aquarium with filling 3. Filter from scrap materials In this article I will show you the process of making a filter from scrap materials. Since the aquarium is not large (about 40 liters), there is no need for a serious and large filter. To work, you will need 2 mm plexiglass trims and several CD cases.
Aquarium with filling 3. Filter from scrap materials To get started, I dismantle a couple of CD cases. I want to try to make them out of them, although the material is thin. I will take this fact into account and where it is necessary to reinforce with overlays and stiffeners. Each case consists of three parts – a cover, a bottom and a middle with a CD clip. To remove the middle part, you need to pry and slightly bend the bottom at the fixing points (4pcs) with a thin screwdriver or just a knife.
 Aquarium with filling 3. Filter from scrap materials First I take the lids, measure 30 mm along the side that has a slight reinforcement.
Aquarium with filling 3. Filter made of scrap materials markup. One lid cracked, in principle not critical, but not pleasant, so I do it as carefully as possible. Acrylic is still thin and does not like unnecessary physical effort.
Aquarium with filling 3. Filter made of scrap materials such a cut, I specially posted for the idea of ​​what part I cut off.
Aquarium with filling 3. Filter from scrap materials Next, I take the bottom of the case. I make such cuts from 4 corners. And I cut it with a hacksaw blade, so I carefully made the first full cut, and simply shifting it with my finger and using it as a stop, I cut off another thickness of the blade. Later you will understand what it is for.
Aquarium with filling 3. Filter made of scrap materials Checking the cut grooves. If not enough, I file it with the same blade. The main thing is that the cut-off part from the cover with its eyelet enters the groove without effort.
Aquarium with filling 3. Filter from scrap materials Once again I check the composite parts. It should look something like this.
Aquarium with filling 3. Filter from scrap materials Aquarium with filling 3. Filter from scrap materials Then I start gluing/soldering. I know about the basics, and about crystal lattices, and about polyethylene, PVC, PLA, ABS, etc. Acrylic (organic glass) sticks together very efficiently, or more precisely, it is fused with dichloroethane. But bad luck, there is NOT MUCH of it left in my bottle! I will tell those who do not know, its vapors are poisonous and the liquid itself has a very great penetrating property. Therefore, until he used it, he stupidly found pores in an airtight container and evaporated. I solve the problem simply. Plexiglas can be simply soldered at the desired heating level. Of course, the seam will be visible and does not look very aesthetically pleasing, but in my case this is not the main thing. Therefore, I take out a rare 40W soldering iron from the tool store.
 Aquarium with filling 3. Filter from scrap materials First, I assemble the parts, set the desired angle, and grab them by the ears, melt the plexiglass with a soldering iron. So the details are less fixed relative to each other.
Aquarium with filling 3. Filter from scrap materials Then I melt along the outer edge, it turns out not very nice of course, but it doesn't matter. The filter will later be hidden by the aquarium lid.
Aquarium with filling 3. Filter from scrap materials Using a steel bar as a support, I sand rough beads with a sandpaper. Already looks more or less.
Aquarium with filling 3. Filter from scrap materials Then I” solder ” connection from the inside. I use the sharp angle of the soldering iron tip and do not forget that the material is thin so as not to burn through.

Aquarium with filling 3. Filter from scrap materials Then I take two covers, I choose the part with ears, there is a reinforcement along the edge.
 Aquarium with filling 3. Filter from scrap materials Mark and cut.
Aquarium with filling 3. Filter made of scrap materials Pay attention to the collar at the bottom of the case, I will use it.
Aquarium with filling 3. Filter from scrap materials I install the cut parts in the indicated place and use a soldering iron to melt/solder. It looks like this:
Aquarium with filling 3. Filter from scrap materials I bite off the protruding ears with side cutters. The length of the parts was not enough, so this is the gap.
Aquarium with filling 3. Filter from scrap materials Earlier I wrote that one part cracked during trimming, I will use it. I cut off the sides.
 Aquarium with filling 3. Filter from scrap materials Using the soldering iron again, I melt the small parts into the gap. Here's the bottom line:
Aquarium with filling 3. Filter from scrap materials Aquarium with filling 3. Filter from scrap materials I cut a hole in thick tube. Size – to fit a thin tube.
Aquarium with filling 3. Filter from scrap materials I insert a thin tube into the finished hole, and inside the thick one, the inserted tube should protrude by almost half of the inner diameter. This will help to avoid the absorption of “living stuff”. And using a glue gun, I glue the joint with polyethylene.

Aquarium with filling 3. Filter from scrap materials I burn a hole in the bottom of the filter in the corner with a soldering iron. Checking that the suction tube comes in.
Aquarium with filling 3. Filter from scrap materials Everything is fine. From the scraps I make the first bulkhead, also using a soldering iron.
 Aquarium with filling 3. Filter from scrap materials Then I take the middle part of the CD case and try it on.
Aquarium with filling 3. Filter from scrap materials I mark the cutting line and cut it off. This part will be used as a cover from the bursting bubbles. The air supply will be active and you need to protect against small splashes. And this detail will also strengthen the construction.

I insert a thick tube into the prepared hole. Immediately you need to locate on which side the air supply tube will come out.

Filter from scrap materials After the polyethylene has cooled, I install an improvised amplifier cover and fix it with a soldering iron. To be honest – that's still something to do! The material is thin, flexible and hard to immediately select the speed and pressure of the soldering iron tip.
Aquarium with filling 3. Filter from scrap materials Again, from the scraps, I install the second bulkhead. In this case, I do not solder it in, but I paste it in.
Aquarium with filling 3. Filter from scrap materials Aquarium with filling 3. Filter made of scrap materials Next I take foam rubber 15 mm. I cut a strip corresponding to the height of the filter. And I begin to place it in the right position. I cropped and tried again to reach the maximum area when working.

 Aquarium with filling 3. Filter from scrap materials Taking into account the direction of movement of water through the filter, I burn several holes with a soldering iron for draining (after pulling out the foam rubber). Approximately closer to the bottom, but not close to the bottom.
 Aquarium with filling 3. Filter from scrap materials Then I burn a couple more holes, closer to the top of the filter. They are made in the compartment where the water is supplied. Needed for insurance against clogging of foam rubber.
Aquarium with filling 3. Filter from scrap materials one more reinforcement, already on top. I just glue it on.
Aquarium with filling 3. Filter from scrap materials Aquarium with filling 3. Filter from scrap materials In principle, the filter is ready. Now you need to come up with a mount. The filter was conceived as an external filter according to the cleaning system, but it should be located inside (under the upper casing of the aquarium). Galvanized wire 2mm is available. I make such hooks from it.
Aquarium with filling 3. Filter from scrap materials I glue, align.
Aquarium with filling 3. Filter from scrap materials Collect, and finally check. Everything seems to be fine, it certainly looks not for sale Aquarium with filling 3. Filter from scrap materials
Aquarium with filling 3. Filter from scrap materials First in-place check. Everything was installed easily, without effort, but it also sits in place confidently, does not dangle.
Aquarium with filling 3. Filter from scrap materials Aquarium with filling 3. Filter from scrap materials This device will be used as a compressor:
Aquarium with filling 3. Filter from scrap materials It is important to note that valves and gate valves must be installed on the hoses. This is especially important if the compressor is located below the surface of the water in terms of level. You can buy it at any aquarist store. In my case, the compressor is standing here temporarily, later it will be hidden inside the upper casing.
 Aquarium with filling 3. Filter from scrap materials I connect the hoses and start. Everything worked, but first of all there was a nuance. Since the foam rubber was dry, the pod was delivered to the first department and that's it! Merged through emergency holes. I had to stop, pull out the foam rubber, moisten it thoroughly, expelling the air from the inside as much as possible. And it all worked. And the next day, everything became almost perfect, the flood was normally saturated with moisture, and in the first compartment the water level hardly rises, all the water goes through a cleaning cycle and is drained back into the aquarium. One of the compartments is planned for activated carbon. He threw in a couple of pills, hissed and settled in that compartment as a sediment.
In short, I'm satisfied. Performs its function. I think in a few days the water in the aquarium will be crystal clear.
