Sand filters vs. bead filters

Here is today's Pond Q&A, with questions about filters and winter

But first, some more readers reviews of 'The Scarecrow'


It works! So far. I received the scarecrow yesterday and
immediately set it up. This morning Mr. Blue Heron came in for
a landing in my pond and the little scarecrow creature went
crazy and Mr. Heron flew away.

He landed on my neighbor's roof and pondered the situation for
awhile. Then tried it again. Little scarecrow went crazy again
and Mr. Heron had had enough and flew away.

The only down side is that the scarecrow sprays joggers and cars,
too. I may get kicked out of the neighborhood...

Now on to today's Q&A...


HI THIS IS ANA in Pt. Charlotte Fl

Please Help me, what is the difference between a sand filter and
a microbead filter? I am in a rush, cause my dad wants a sand
filter and I don" think that is the right kind.

Thank you Ana in Pt charlotte



Well Pat, let's just say that 'Sand' Filters are great for
swimming pools, but terrible for ponds. In pools, they work
effectively to 'polish' the relatively clean water by filtering
it through very small granules of sand. Add some fish waste and
other organic waste to the equation, and you've got yourself a
mess. In ponds, they clog quickly, require almost daily
backwashing, and can also grow anaerobic bacteria (smells like
rotton eggs).

Bead filters, on the other hand, were designed specifically for
fish hatcheries and ponds. A Bead filter provides excellent
biological filtration, due to the large cumulative surface are of
the beads for colonizing beneficial bacteria, and they are also
excellent for polishing the water without clogging easily. They
are also easy to backflush, easy to maintain, and easy to use.
In short - we love 'em!

Who knows what University invented the first 'Bead Filters' for
use in commercial fish hatcheries? Send in your guess to us at Winners will receive a

Hello First of all i love your Q & A's. I cant tell you how many
of my questions/concerns have been answered just by reading
these. I live in western Pennsylvania. The change of seasons in
this area are so extreme that today could be 75 degrees and sunny
and tomorrow is 45 degrees with rain.

I know not to feed the fish (1 koi, 2 comets/shubunkins and 10
new babies) after the water temp drops to 50 degrees. But my
water temp changes as often as the air temperature. My question
is if the water temp fluctuates should I still resist the urge to
feed them until Spring? This is the first winter that I wlll have
left the fish outside. Thank you in advance. Kim Ladasky,
Pittsburgh PA.


Hi Kim, thanks for your compliments.

Ok, well it really depends. You wont necessarily harm them by
feeding them a little here and there, just use your best
judgement. But you definately don't want to give them a 'feast'
right before a cold spell. Again, fish don't have stomachs and
the good enzymes that digest their food are less present in
cooler temperatures, so excess food can actually rot in their gut
if they are feed too much when it's cold.

So, a 'light' feeding sporadically would be fine untill it cools
off, but then again - they will survive just fine without it.

Hope this helps..


Happy Pondkeeping!
