Tropical fish farming tired too worried, began to raise some native fish tanks, with 40 small tanks, about the fish tank up brown algae considerations and lights must be related, raised for several months of native small fish tanks, more than a dozen native fish, seven or eight small pomfret, two small shrimp goby, more than twenty medaka were chased by the gobies to bite the remaining two, there are five or six wheat ears, in a few ponds of water weeds, the bottom sand is the river sand mined in the mountain stream, studied a variety of filtration, after comparison finally made a simple swamp filtration with sand and gravel, The water pump uses a 6W side suction pump, the power is very large, the water flow is too strong, fortunately you can adjust the water flow, only a little gap is opened, the swamp filtration effect is very good, the water quality is very clear. I have been illuminated by a table lamp, about 3000K or so of warm light table lamp, fish tank and stone grow a lot of small green algae. Later, for the bathtub effect, the table lamp was replaced by a led pure white light, and within a week, there were a lot of brown algae growing on the fish tank and on the stone. It is speculated that the long brown algae has a lot to do with the light, perhaps because of the intensity of the light, and the god instructs. Share a few pictures of the fish on the top.
