“Half a year ago I purchased tubular air diffusers made of porous polymeric material — I don’t know what the name is — bluish-green. Recently, the holes have become clogged, is there a way to restore the quality of the tubes? ”

Partially restore performance will help the next simple method. The tube removed from the aquarium is thoroughly rinsed in running water, simultaneously treating along the entire length with a brush with a hard bristle, and the internal cavity is filled with water, after having removed the adapter tip.

Photo Tubular Sprayer

Putting the cap in place, the tube is placed for several hours in the freezer compartment of the refrigerator, then removed, immediately doused with boiling water over the entire length and washed. The whole procedure is repeated two or three times. The treated tube is dried for 24 hours at the radiator of the room battery, after which the sprayer usually becomes ready for reuse. When connecting to a water pump for the first time, it is necessary to set the maximum air supply mode for several hours, this will remove the remaining calcium salts from the pores of the tube.

If the measures taken were not enough, sprayers for 2-3 days immersed in a strong solution of food citric or acetic acid. After that, again washed and repeat the procedure with freezing.
Porous plastic tubes withstand boiling water treatment well, but in no way can it be “boiled” in the vessel – this will lead to the deformation of the product and a noticeable loss of its working properties.
Problems with nebulizers occur much less frequently when using an air-pump which is known to be of greater productivity than is necessary under the conditions. During operation, it is necessary to periodically turn it on at full capacity for 3-4 hours, thereby ensuring the cleaning of micro-holes in a natural way. As a result, sprayers will have to be treated less frequently.

“Tell me, what is the best way to apply a filter for an aquarium with fry? I grow catfish fry, which need very clear water, but without a strong jet created by the pumps. ”
E.Zatymova, Nikolaev, Ukraine

In maintaining the hygiene of small vessels, mounted external filters-pumps of the “waterfall” type with a wide and flat drain outlet have proven themselves to be effective. Their design provides a flow of purified liquid a gentle stream of lingual form. It smoothly mixes with the upper layers of the vessel’s water, without creating excessive currents that can injure the young ones.

In addition, the working chamber of some models has a volume of 1-1.5 liters, which further increases the total amount of fluid circulating in the system – for small tanks this is quite significant. The power output is easy to choose empirically, watching the reaction of the fry.

Three stages of purification are necessary to achieve maximum efficiency from filtration and to obtain crystal clear water. The first two involve the use of a “standard” waterfall filter cassette and an additional sponge put on the water intake tube. The latter degree involves the use of so-called flotation filter material, which is a piece of synthetic fabric – it can be nylon, nylon, awnings, parachute silk. The most important thing is to properly fix it in the drain chamber of the pump. The method of fixation depends on the design of the device, the main thing is to position the fabric with a bag just before the drain tray, so that the flowing water cannot pass it. At the same time, the material is inflated like a sail, the final flow slightly weakens and dissipates better. These three stages – almost the maximum that can give a soft mechanical filtering. It is only necessary to closely monitor the condition of the flotation cell and, if possible, flush it more often. For fry diansm, loricaric catfish and other fish species that are sensitive to mechanical suspension and dissolved organics, this filtering method is necessary only in the first two weeks of life, provided that about 80% of water is changed daily.
