If not caught, you could accidentally siphon out your entire tank, leaving your fish high and dry!Ĭheck valves prevent this back siphoning from occurring but are not required. If the pump is below the water line, gravity will force the tank water down the hose and spill into your unit.

Most of the pumps in this review include check or return valves that will prevent back siphoning. As with all other saltwater tank components, be sure to clean your air pump regularly to ensure it stays free of salt crust from evaporating tank water.Ĭheck valves create a one way route for air to enter your aquarium, but not return the opposite way.

"Use caution with higher pressure air pumps when keeping small or delicate species like betta-the increase in flow may make movement around their tank difficult!"

Such a decrease in the labor force would result in a slowdown in the growth of the national economy, and affect the sustainability of the welfare state, Etla warned. If the current low birth rate and the level of immigration forecast by Statistics Finland continue, the working-age population will drop by nearly 20 percent by 2070. The report by the Research Institute of the Finnish Economy (Etla) examined the economic effects of work-based immigration, and how immigration can compensate for the effects of Finland’s aging population.Įtla said that the level of immigration required to boost the workforce is almost three times the actual level predicted by Statistics Finland: around 15,000 people annually.įinland’s working-age population began to decline at the turn of the 2010s, when the “baby boomer” generation moved into retirement. ![]()
