Oxigenador aerador pra caixa d'água, tanque e açude com peixes, aperfeiçoado pra não queimar.

One of the biggest problems for fish farmers is oxygenation of the fish. Conventional pumps consume a lot of energy, often making farming unviable. Having this problem, I got one of the cheapest pumps on the market, and with one of the lowest consumption, but it burned out very quickly, so I did a process to make it last much longer. This pump is the universal washing machine drain pump, found on ML for approximately 50.00.
