Are You New To Garden Fish Ponds?
My friend Peter J May, one of the UK's top water gardening
landscapers puts it best. He says "To have the sight and sound
of water near them in a garden has been an almost instinctive
urge to people of all cultures in all ages. Now as then, the
beauty of reflection, the relaxing sound of moving water and the
life that it attracts make the water garden as desirable to many
people as a lawn or patio." What a beautiful description yet so
many water features and fish ponds do not achieve this goal. Let
me explain why . When a water feature is installed and
especially when goldfish or koi are placed into a pond a cycle
of events takes place briefly described and simplified as
follows. The fish are fed and the waste products are released by
natural metabolic processes. These waste products are
essentially ammonia and if allowed to build up the ammonia
reaches levels that are poisonous to the fish and the fish die.
Do you remember that lone goldfish in a goldfish bowl when you
were a kid? The fish lasted about a week then died. Yet goldfish
are capable of living for many years. Well the fish died from
poisoning itself. In a pond environment it is absolutely
essential to install 2 things. 1. A pump to circulate water
containing life-giving oxygen to the fish and to the bacteria
that purify the water s make sure you select the correct pump
for your own pond or waterfall 2. A biofilter in which bacteria
grow and thus provide a mechanism for purifying the water
similar to what happens in a natural pond. These bacteria
convert the ammonia to nitrate fertilisers that can be used by
pond plants ... UV & bio filters. The pump must circulate water
through the biofilter 24 hours per day or the bacteria will die
from lack of oxygen. You can build your own biofilter for a
small garden pond up to 1,000 litres (250 gallons) very simply
and cheaply using Alfagrog (called Supra in the USA) or you can
buy one for a small sum of money if you choose wisely. Virtually
all fish ponds go green in summer owing to large concentrations
of suspended algae forming in high sunlight, warm water
conditions. The only effective way to keep a fish pond crystal
clear is to install many plants and in most cases even with
planted ponds to use an ultra violet light that kills the algae.
These algae (algae are tiny plants that multiply by
photosynthesis) are then removed in the biofilter. The simplest
equipment to install which will guarantee you crystal clean
garden ponds are called combo filter/UV units ... in other words
a combined biofilter and Ultra Violet light (UV for short) all
in one to make for easy installation. Golden rules of fish pond
keeping: 1. Pump water into biofilter 24 hours per day 2. Do not
overfeed your fish and buy the best quality fish food you can
afford. 3. For crystal clear water all year round buy an UV
light ... normally buying UV and pond filter combo is best and
cheapest route to go ... see above
