Why a Bottom Drain?
A bottom drain is the single most effective waste management tool in a Koi pond. Fish waste settles to the lowest point - a bottom drain removes it continuously before it breaks down and degrades water quality. The aerated version maximises this effect by creating a sweeping circular current.
Tip
For ponds over 5,000L, use a 4" bottom drain. In larger ponds, multiple drains ensure complete floor coverage. Contact us for installation guidance and sizing recommendations.
