Cloverleaf Bioprotein Fractionator  Ref: CLEAFFF
	The control valve should be adjusted so that a slow drip pattern is seen going into the external waste bowl. Heavy rain, water changes and feeding the fish will have a temporary effect on reducing the drip flow rate (perhaps to nothing), however no further adjustment should be made, and the system should be left for normality to return. Periodic cleaning of the Inner Perforated Transparent Collection Tube is advised, with access available via removal of the base plant. For vertical stability of the Foam Fractioner device the circular base plate should be screw fixed down to a suitable medium (concrete paving etc), or alternatively fixed to a plank of timber decking. To reduce surface agitation and noise the return pipe to the pond can if required discharge via a bend and short vertical drop with the bottom of the pipe drop set 30mm above the pond surface. All pipework should be 50mm diameter. In the event of using medications in the pond it is advisable to adjust the foam fractioner so that its extract abilities are terminated, however under such circumstances the device should ALWAYS be left running due to its production of oxygen, and its live biological bed.
