Hello,
I just moved into a tropical bungalow which has a shallow indoor pond. Its
new but hasn't been used for several years. I switched it on over the
weekend and its seems ok. But the water flow is dead slow at the end of the
pond. And I'm worried about it breeding mossies. there might also be some
problem with it. I'm hoping that some of you here who are more knowledgable
about it can help me and offer some constructive advice.
(I can't ask the previous owner; he moved off in a hurry overseas)
But first some info... Its large - measuring 14 feet by 14 feet. But the
depth is shallow- and measures an average of only a few inches.
Its flanked on both ends by two drains where the pumps and outlet pipes sit
(inside). The two pumps and what appears to be a drain value are on one end;
the outlet nozzles and pipes are on the opposite drain- which is on slightly
higher ground.
When I checked it out, the drains were still full of old water. I filled the
pond full of water then turned on the pumps. One section worked. The other
section didn't; its pipes are embedded into the concrete and I assumed join
the 2nd filter pump.
So I had water nicely flowing on the left side of the pond. Whilst the right
side was slightly stagnant. Concrete paving steps line the middle section of
the pond and prevent the working side from helping out the non-working
section.
To cut a long story short, the problem is that the pond is too shallow on
one end. The flow of water is not vigourous or flowing in 60% of the pond
and in certain section - the water is dead still.
Whats the best way to prevent mossies from breeding in the stagnant parts of
the pond. Even if I stop the pumps, the water still sits in the drains and
does not go away.
Much obliged for your kind comments.
Sounds like perfect water for some of the tropical killifish species.
They are perfectly happy with slow moving or even still water and will
wriggle into quite shallow water to nab a tasty larvae.
There's some real killifish experts in rec.aquaria who might suggest
species and where to get eggs. Male killifish are brightly colored too.
