Pond facing severe algae bloom |
Mild greenish pond water with a little bit of algae is
actually beneficial for your goldfish as it helps to provide some extra
nutritious foods to enrich the diet of your goldfish and overall it also clean
up the water. However, things may turn to worse when algae growth becomes
uncontrollable and instead of bringing some positive effects, it will bring the
negative harm instead. Algae bloom not only depletes oxygen content in the
water when it rots but the slime layer that builds up on the surface of the
pond will prevent oxygen will dissolving into the water. On worst case
scenario, layers of slime actually get sucked into the filter intake and this
jams the whole filtration system making the whole condition become anaerobic
(lack of oxygen). Pond experiencing severe algae bloom if left unchecked will
even kill your goldfish.
It is almost impossible to totally get rid of algae but
however, controlling the algae quantity to low level should be your main
agenda. Although many goldfish keepers that I’ve met lament on how hard it was
to check the greenish slime buildup, but however, if you follow these few simple
pointers, nothing should be difficult. But first, in order to deal with the
issues, you must first understand what causes algae bloom in the first place. Most
types of algae are unicellular microorganisms and because of their simple cellular
structure, this allows them to grow and regenerate quickly to produce in
numbers. Excessive growth of algae is actually driven by the presence of
phosphate (imagine it functioning as fertilizer) which is derived from the
breakdown of fish waste and because goldfish are heavy eaters and at the same
time discharge a lot, it is not a surprise that phosphate is always readily available
in the water. Apart from waste, sometimes, uneaten fish food will also
contribute to the pond water phosphate content and therefore, these are
something that you need to take note of.
These are certain things that you can do to help control and
prevent algae bloom. First, regularly clean your fish pond and make it a habit
to remove whatever waste you can see floating in the water. Dead plants and
rotting leaves can accumulate and then contribute towards the phosphate
content. Another effective way to reduce the phosphate content is by planting
floating plants like lilies which will compete for the nutrient, and thus
directly helps to control the algae. Usually a mature pond with healthy
population of water plants will rarely encounter issue on algae bloom, thus
this should be your direction if you prefer biological method to deal with it.
However, a note of caution though, the plant itself will also eventually rot
and die off and thus it still goes back to the cleaning regime that I’ve
mentioned earlier.
Another possible approach but deemed costly is the
installation of UV sterilizer. Although it is somehow effective but bear in
mind that the lamp needs to be constantly changed and thus will contribute
towards maintenance cost. Some people resort to hard fast approach using
algaecides which is basically a mixture of chemical solution that works to kill
the algae but claim that it will not harm your goldfish. Although that is what
stated on the bottle, however always use it with caution. It might be poisonous
to your goldfish if you accidentally overdose and thus; there is always a risk
there. Some people will take the extra step to totally empty out the pond to do
a thorough cleaning and applying the algaecides but this will take a lot of
work and time. In the end, to avoid all these hassles, always remember to
regular clean the pond, test the water and make it a point to control how much you feed to your
goldfish. Avoid excessive leftover at all cost!
