We have had a pond for a little over a year now. The pond is in-ground, EPDM
lined and roughly keystone shaped.
It measures about 10 x 12 feet at the wide end and about 3 feet at the
narrow end. There is a 2.5 to 3 foot waterfall on one side of the narrow end
and the depth slopes from 12 inches to about three feet. It holds about 1800
gallons by my calculations.
The pond now has about 25 goldfish (we started with 16) ranging from 2
inches to about 9 inches (all sizes estimated). Lots and lots of plants
covering at least 60% of the surface. Lillys (5), pickrell (3), new lotus
(this year) not blooming but with lots of aerial leaves, impatiens, mint,
cattail, water iris and a few others I have forgotten the names of.
The pump is a 4,000 gph and I run it 24/7. The filter is a stock tank, 150
gal, with lava rock. Pumped water goes to the filter and gravity feeds from
there to the falls. The company that put in the pond took care of cleaning
this spring. I do the rest with a pool vac and Shop Vac.
Water is clear to the bottom and test readings are good. Oh, yes, we live in
Springfield, MO which I believe is Zone 5.
I kept the falls and pump running all winter and used a stock tank heater to
make sure there was never a complete freeze-over. Lost one goldfish over the
winter, but never found the carcass when all were taken out for the spring
My problem, if it is a problem, is that we have never had any babies. Am I
doing something wrong?? I can't believe all 25 are the same sex. Everytime I
read about someone on this group having more babies, I get just a tad
Sorry for the verbosity. I know from lurking that some of you will want to
know the details before you address my situation.
Thanks, in advance, for your advice.
