This advisory pertains to situations where the the Solids Handling/Waterfall Pump 2000 will be used with the Matala BioSteps 10 Gravity Discharge Filter. The 2000 model pump generates too much pressure for a single Biosteps filter. Thus, two filters will be needed to filter output from the 2000 model pump, connected to the pump using a tee fitting. Please contact us for further consultation before purchasing these products together.
