Filter question

The first canna of 2009 starts to open in my bog garden.


I get email with pond questions. I got this one a few days ago and thought I would share it with you.

Question: I would like to put a 25" round by 15" deep tub. If I put in a bunch of grass, 1 drawf lily, 2 regular goldfish with a pump hooked up to a spitter will I have a successful little pond? Do I need a filter? What size pump would I need. The spitter will be place on some flat rocks at the edge of the pond. I don't plan on feeding the fish but will feed the lily.

Pondlady sez: Yes, you will be successful and need no filter. Don't feed the fish and put a couple of bunches of grass in the water. Feed the lily one tab a month. Use a pump that will pump about 140 gph depending how high the spitter will be. The spitter cannot exceed 12" in height or the water will splash out.

Koi and Goldfish eat their babies

Question I received lately: I have Koi and Goldfish. I feed them daily. Why don't I have babies?



Pondladay sez: Chances are the fish are eating their babies. They are not good parents.
You must feed koi. Goldfish can exist and live well eating off the plants in the pond....unless you have koi who will eat them all.

The more you feed them, the bigger they get and the hungrier they get. Sooner or later your bio-load will be too heavy and your biggest fish will die, but in the meantime, your fish will eat every baby they catch.
