Hello willsniffer

w have a 450 litre pond, pump for fountain going to small
w pressurised filter bucket doodah. Tried various eco methods
w such as ramshorns etc, but what does anybody recommend when
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.


Duckweed doesnt exactly help you see the fish if you have enough of it to
get rid of algae!!
