Alkinity was around 80 ppm at start of year. dont have any DO numbers. fish seem to be happy during mornig feeding an evening feeding. The pump i got is a sump pump the drains basements, i have it floating in a block of foam so its only pulling off the top 6 inches of water an shooting it into air 12 feet for oxgen will this help? or is it really wastein time to have it?
