First, the physical removal method, popularly speaking, is to artificially remove the algae in the straw tank. Prepare a magnet brush or fish tank brush first, brush with this brush, and change the water immediately after brushing, which can get immediate results. However, this method has obvious shortcomings, that is, it is more troublesome and tiring, and the small corners that cannot be brushed can not be removed.
The second is to use algaecide, and each method has its advantages and disadvantages. This algaecide has a very good effect on algae on aquatic plants and submerged trees, but it will do some harm to the organisms and ecosystems in the tank.
Third, biological algae removal, that is, adding some tool shrimp and tool fish. In fact, this method is advocated and practical, that is, the algae removal time is longer than the first two methods. Of course, different creatures eat different algae, for example, black shells eat green algae, black flying foxes eat black hairy algae and so on.
Too much phosphorus or nitrogen in the tank will induce algae similar to black algae, so the number of fish in the straw tank should not be too much or too little. A liter of water is a centimeter of fish, and the fish here refers to small fish.
These methods are all applicable, but before removing the algae in the haystack, you must choose which method to use according to the situation of your haystack, and also see which method can play an effective role according to the situation, and then judge the feasibility of this method.
