Pond Q&A - Fire Ants, Napalm, and Frozen Fish?
In today's 'Pond Q&A,' we have two equally important questions
(smile), and at least one really good answer...
I enjoy reading your articles.
I have two 6500 gallon ponds with a large waterfall and a bog
that empties into a stream that flows to the lower pond. My
problem is FIRE ANTS! Those pesky little *&^%$*&)(&^ have taken
up residence in the bog and along the stream. I live in central
Texas and I have been able to control the fire ants in my yard
with various chemicals, unfortunately, I cannot use them in the
Is there anything I can do to eliminate them in the bog without
harming my fish and plants?? Any assistance would be greatly
That's how I feel about those suckers. Just nuke them out of
your yard once and for all. Other than that - I really don't
have a good alternative. (Let me know if you find one, so I can
rid my self of them also...) Or maybe one of our readers has
some good advice...
I have a small pond and I live in Pennsylvania (southeast) so we
get cold weather.
The pond is 16" deep in most of the area with a slightly deeper
center (not 2').
I purchased a submersible pond heater for small ponds and also
have an air pump.
Between the two I am hoping that the water will not freeze solid
(as it did last year).
Do you think my fish and frogs will be safe with through the
winter this set up? The pond is about 6' x 3'.
Well the normal minimum for keeping ponds from freezing solid,
and wintering over fish and koi is around 18" - 24", depending on
how far North you live. So, either way - your pond is a bit
shallow.. But as long as you have a winter de-icer, that should
do the trick. Just make sure you bought one with a metal 'guard'
that keeps the hot heating element away from the plastic or liner
edge, unless it's a concrete pond - then you're all set.
For the aerator, I'd recommend lowering it to just below the
surface of the pond, so as not to necessarily circulate the pond
water. In winter, the pond will have 'thermal layers' of
different water temperatures, with the slightly warmer water at
the bottom, and the colder water near the top.
By having your airstone all the way at the bottom of the pond,
the rising air bubbles will create water circulation, and will
actually cool the warmer pond water at the bottom of the pond.
This is also why we don't recommend running your pump in winter.
Hope this helps...
