Water Lilies / Fish Food

Today's Pond Q&A

In this issue:

- Feeding Water Lilies

- Feeding Fish and Water Temp


Question #1>

Hi Carolyn,

I have a question for you. I have about a 2000 gallon pond with
about a dozen water plants in it. My question is why are my plants
so small and don't seem to want to grow?

The water lilies bloom but the leaves are not big. What do you
recommend for plant food, liquid or pellets?

Appreciate your help.


Answer #1>

Hi Lynda,

Lilies are heavy feeders. If you do not keep fish in the pond, then
I would suggest using Plant Tabs. If there are fish in the pond
then the additional plant food, either liquid or tablets, would
probably be more likely to produce algae than blooms.

In ponds with fish, I recommend using Microbe-Lift Ensure or Bloom
& Grow, both of which contain no nitrates or phosphates but contain
enzymes and micro- and macro-nutrients to stimulate uptake of
nitrates and phosphates by plants.

Without fish to provide the necessary "fertilizer" to the water,
you have to feed these plants yourself.




Question #2>

Hi Carolyn,

I just stumbled into your great website while surfing the web for
some fish info. I got sidetracked by your Archives site for fish &
pond Q&A. Great stuff by the way.

My question pertains to feeding and temperatures. You say the water
temp is what to measure, not the air temp.

I have a 120 gal above ground patio tank/"pond" with a few sarassa
comet goldfish. I live on the west coast and we have fairly mild
weather but the day / night ambient air temps can fluctuate from
say, 75 deg F daytime to mid 40's at night on occasion.

How would you calculate your water temps or the average temp based
on that?

Also be aware that because the pond is made of recycled black
material it draws heat from the sun and the concrete patio and also
loses temp fairly quickly if the weather snaps.



Answer #2>

Hi, Michael,

Actually I would expect the concrete to hold the warmth for a good
while at night, which is a blessing, not allowing any sudden
temperature changes.

To gauge the temperature, I would go with the daytime temperatures,
provided there is sufficient daytime for the fish to metabolize
food. When the air temps drop to the mid 40's, if the water temp
drops that low the fish metabolism will practically cease and food
will not be processed. It just may take a day longer for the food
to exit the fish.

The median temperature is certainly in line with a good wheat germ
food, which is easy to digest, but considering the temperatures go
up into the 70's during the day, you can pretty well feed them
anything. Just keep in mind, you have a small tub of water so
don't overfeed or you'll compromise the water quality quickly.
