Last I clean the pump was in September, thats about 5 months ago. Its still running fine, I am going on a trip in 2 weeks time and I feel its time to do some pump maintenance.
Its full of fish poo but its still going strong, cleaned and full flow again. This is a 110 watt 220 V AC Single Phase Pump rated at 4500 L/Hr at 0 head.
Once done, throw it back in and switched it ON, as mentioned before I switches OFF this pump at night this could be the reason why its such a long period in between cleaning.
I need to top up the Fish Tank,, about 1 ft of water needed.
