“why have all my largest fish died overnight” – the  pondkeeper should not  think that  a small waterfall, or the agitation from a filter return pipe, would  be  fully able to provide quality (life saving) levels of saturated oxygen. Consequently additional man made  devices are vitally important, especially during warm summer periods, even more  so for those with heavily planted ponds, or those unable to add airstones within their filter systems. (Alas, not everyone is fortunate enough to own a Cloverleaf multi-bay system).

Fish, and indeed the beneficial bacteria that colonise the mediums within  our filter systems demand good levels of oxygen saturation for survival and maximum development, and Cloverleaf  offer a range of devices to enhance the health of all ponds. (Air pumps not supplied).

It is  impossible  just to look at  a fish and  conclude that oxygen saturation levels are sufficient.  Test kits (as produced by numerous companies) may not be perfectly accurate, but will provide a good indicator of potential problems. (Readings should be taken at different times throughout the day).

Bottom Drain: This 100mm nominal (4”) bottom drain suitable for gravity fed filter systems incorporates a removable dome with a large integral surface mounted circular ring air diffuser – supplied complete with 10 metres of air tube.

For those keepers who do not like to see too much agitation in the centre of the pond, then the air pump can easily be linked to a time switch. when eg. it is only operational from say 6pm in the evening around to 9pm the following day.

Venturi: Suitable only for a pressure pump input, and ideal for connecting to the outlet/return on gravity fed filter systems the venturi unit is a  highly efficient device for improving oxygen saturation levels. The sound constructed Cloverleaf Venturi is engineered to offer the keeper the facility of swopping between the two different cones as supplied, and thus provide greater control over distribution.

(Where desired the Venturi can of course be run from a separate dedicated submersible pressure pump)

Obtaining a good rotational spin in a vortex bay without disturbing particles or waste that has dropped out of suspension is a vital requirement, and this is why on pumped supplies to multi bay filters Cloverleaf have introduced the option of fitting a diffuser. This simple push fit device (with facility for incorporating a stepped hosetail pipe connector- up to 40mm/1.5”) has been specifically and carefully designed for the task at hand. Water entering the large bore horizontal inlet is diffused to the point of converting the flow into a series of horizontal and vertical jets within the inlet pipe, and this amalgamation diffuses the direct horizontal velocity flow when finally entering the vortex.

This device also makes a good birthday surprise present for the lady who has everything.
