Hello willsniffer
w have a 450 litre pond, pump for fountain going to small

w it comes to a decent filter system +/- UV filtering? The
w fish are fine but it would be nice to see them once in
w a while. Thanks
Oxygenators, covering plants (lilies, even duckweed) and time.
Algae blooms because of sunlight, lack of oxygen and excess nutrients.
I've got a large system of connected ponds here of about 8,000 gallons
with 8 adult goldfish and about a hundred 1st year goldfish. Water is
crystal (now, it wasn't earlier this year) and I don't have any
additional filtering systems. Just plenty of oxygenators, several
waterfalls (same function, just noisier) and coverage.
