That, the customer factor, is something that we all must deal with, but the pondbuilder must know the correct way to construct and maintain a balanced eco-system. How else can they adequately explain to a customer why their waterfall looks like a Chia pet on steroids and the proper corrective/preventive measures are not the use of weed killers, which is exactly what algaecides are, or questionable devices that are proven to wreak havoc on the food web and probably cause long-term irreversible damage to their fish. The customer should be informed of proper husbandry and told that if they choose to ignore these facts then they will reap what they sow, which will be a bumper crop of algae.
