Note to all. The EcoPlus7 air pump has an air pressure rating of 5.1psi. This means it will produce air down to 10ft deep maximum. Operating at the 10ft depth forces the pump to operate under maximum conditions (stress) while it is running. IMO this will shorten its useful 'life span'. The pump will last longer if it has to only push air 6-8ft deep. Generally the deeper a pump operates the less air volume it is able to produce compared to the 'open' air flow.
