I will begin with a short preface. Although I have a long time aquarium 140 liters, but I consider myself only an amateur. Since he kept the fish purely for the soul (it is necessary to do something). In the winter, I had time to look after my pets, and in the summer it wasn’t up to them, it happened, I’m going to launch so that I had to catch skeletons. And sitting next winter evening, I looked at my aquarium and decided it was necessary, something to do so will continue, can not more. I wanted all the time to achieve clean stormy vegetation, but it worked only partially. Even when replacing the internal filter Atman f-102 I purchased, more powerful Atman f-104.
The results of those that I wanted, did not work. So I decided or thought visited me, I don’t remember, but I went to the Internet and began to look for how to achieve a normal state and found that in addition to internal filters there are external filters. In short, having familiarized myself with them, I came to the conclusion that this is what I need, but here prices have bitten a bit (Kiev Internet prices 800-1400 grams. The cheapest Chinese Atman CF-800 —- 600gr.).
After a very long deliberation, I came to the final conclusion that it was necessary to make homemade products. Why I decided so, firstly, the availability of spare parts covered the tap went, bought, or even the motor from the internal filter, we have them in stock, went to buy a filter, put the motor from it and no problems. And so to go to Kherson is there something or not, and this all the time, the fish will not wait. But since we simply don’t deliver 200 pipes, we don’t use it, only 160 and 100 were in demand. When I came home, I was even a little upset, but measuring the pump from an Atman f-104 filter (according to its characteristics, it was Description: Power – 38 W Capacity – 2000 l / h Water rise – 2 m) I was convinced that everything should stand only very much in the butt. Since there were no 350mm couplings so long, I took a meter-long piece of a 160mm pipe and plug. I decided to connect all with plastic compounds. Compiled a list of what is needed, and after buying all the necessary things, he set to work.
Once again, having familiarized myself with the internal filters, I took the filter as a basis. Eheim Classic 2213
Specifications: For aquarium: up to 250 l
Productivity: 440 l / h
Water lifting height: 1.5 m
Filter capacity: 3 liters.
Dimensions: 160 x 160 x 355 mm.
Power consumption: 8 watts.
The height of the pump Atman f-104 was 10 cm, I added it, and it turned out 160x160x450mm. I began to think about how to make the bottom, first cut from a thick plastic circle on silicone and self-tapping at the ends, but then it dawned on me, but what if you heat the pipe and insert the cap. I took a cut off piece from the main one and went to experiment. On the gas stove (the biggest burner), I began to scroll over the flame (I had to wear mittens, my fingers were hot) the pipe softened over time, it became such an elastic rubber, and I managed to insert a plug. Realizing that everything will turn out very well, I did the same thing with the main workpiece (if anyone wants to make something like that, you shouldn’t lower it to the flame so as not to hurt the plastic, you need to scroll the pipe evenly and, trying it out for elasticity, you don’t need 50cm so that will be trained on what)
So the bottom I have done, I decided to do the upper part, everything worked out, even better than I could imagine, the nose from the pump came right up to the 20 corner, it remains only to lubricate the plastic with aquarium silicone and everything is okay. The engine had a ledge at the back, I decided to make a retaining bar so that the engine hung not only on the nose, but also rested against the bar (everything also missed with silicone). if I pulled it out, then I cut a 24 mm wide section from the experimental tube on the stub, which would serve as a stop.
When installing the Mayevsky crane, I decided to drill a hole so that Mayevsky, when screwing, cut the thread a little bit with a napfilk and everything turned out (also planted on silicone) I bought a fitting for the wire on the market (they are, different diameters are used for street lamps or electric motors)
Since I was not satisfied with the loading of filtering elements, both in the German filter and in the self-made filter published on this site, I decided to make the loading baskets as in filters Eheim Professionel 2224 and so on.
Not finding the right packaging, I decided to make a basket from the remaining pipe. I made three pieces of 8 cm each. You can do two under it and fill up the rest with a sponge if you find 160×160 in diameter (having cut off 8 cm I cut this piece along then put it in the pipe and outlined how much it should be cut off, big, so that the basket went effortlessly; at first I glued it with plastic glue, and, for strength, made holes, twisted it with copper wire, I drowned it in grooves made with wood burner. Cutting the bottom and drilling the holes could be put on the aquarium silicone, but I decided to play it safe (I didn’t want the bottom to come off when pulling out and the entire filling spilled out)
I cut a strip of 3 mm and pasted it. She put her on silicone and twisted the wire from four sides, also made grooves and drowned. After that, planted the bottom of the silicone. Handle also made of pipe. You can use bolts with tacking, but I took a rod from a plastic dowel (with the help of foam attached to the wall) cut into 2 cm barrels and with the help of a bolt heated on the stove, it burned down with a hat.
Yes, with a tati when the pipe is cold, I gently tapped the plug from the pipe. In the plug, I inserted two plates in order for the baskets to be installed against it. I drowned them flush with the edge. When installing the plug is coated with aquarium silicone and planted until it stops.
By the way, if you use a household filter, then try to take a crane with Mayevsky from the top, and not from the side as I have for a better air outlet, I had to drill a small hole and tighten the screw with an eraser, in the photo I showed the arrow. I screwed the flask onto the special clamp on the photo; this device can be seen in the photo, four bolts with sheep were attached to it, which pressed the top cover from opening. Thanks to this, I can separately open the lid without touching the flask from the household filter.
For sucking water into the filter, I used a plastic bottle of 0.5 liters from the drink, cut off the neck and already finished plastic plate with holes (drilled small holes so that the fish did not suck in) screwed with a wire. If now I need to clean, then you can easily unscrew this flask. I filled the filter like this: the first basket of claydite cut into half with plastic rings cut from plastic corrugations for electrical wiring (by the way, they resemble branded filler)
a second basket with a porous sponge for bacteria, a third fine-porous sponge and a pad of synthetic winterizer. You can get acquainted with the methods of filling filters on the site
If the volume of your aquarium exceeds 400 liters, then I recommend to make a Samp – biofilter.
