fish pond

Your pond looks great with healthy fish water nice and clear for the time of year this photo was taken, do you have a filter systom?.. I have a small pond but get lots of algae any tips on how to keep it down..

photo was taken last summer scottie now i have only one fish left thanks to a black cat that comes into the garden every night , its had my fish so it will have its chips if i catch it. only joking cat lovers ,but it has been seen with my fish in its mouth,no i do not have a filter systom scottie , just put plenty of oxygenators
