Floating pellets for koi and pond fish, for water temperatures of 12 to 25 °C

All Seasons pond fish food, in floating pellets, feeds koi carp, goldfish and other ornamental fish in a garden pond. It contains 33.5% protein and 8.9% fat. It is suitable as long as the water stays between 12 and 25 °C, in the amount the fish eat in 5 minutes.

These floating pellets are intended for koi carp, goldfish and the other ornamental fish of a garden pond. They contain 33.5% protein and 8.9% fat, an intermediate value that allows them to be fed over most of the year. The pellets stay on the surface throughout the meal, which lets you see how much is actually eaten and skim off with a net whatever has not been taken. Anything that sinks to the bottom decomposes and adds to the nitrogen load that your filtration then has to process.

🌡️ Water temperature

Pond fish are cold-blooded animals, so their digestion follows the water temperature and not the calendar. When the water cools, intestinal transit lengthens by a factor of 2 to 4 between summer and winter, and gastric emptying is prolonged by the same amount. Food given in cold water therefore stays longer in a slowed-down digestive tract, and a greater share of what it contains is no longer absorbed. This food is suitable for use between 12 and 25 °C. Below this threshold, your fish stop begging for food of their own accord, and this halt in feeding is normal behaviour.

🥣 How much to feed, and how often

The rule that takes priority is the 5-minute rule. Give the amount your fish eat in 5 minutes at most, once or twice a day, then remove whatever is still floating. This rule adjusts itself to the temperature and to the appetite of the day, which a fixed percentage cannot do. For a first weighing out, allow around 1.5 to 2% of body weight per day for adult fish, a one-year-old fish eating more. In an aquaponic system, this ration governs both the growth of your fish and the nitrogen your plants feed on, and any increase shows up on an ammonium test before it shows on the leaves.

Above 20 °C

Digestion is quick and appetite is strong. A richer feed, at 39.5% protein, is then better suited to a growing season.

12 to 20 °C

This is the window in which this feed is entirely sufficient. A single bag covers the period, with no change of formula or routine.

Below 12 °C

The ration is reduced, then stopped. Floating wheat germ feed, limited to 5 to 15 °C, takes over until spring.

The thermometer dictates the formula

A floating thermometer tells you which formula to open, since it is the water temperature, read in the morning, that determines when to change bags. A set of kitchen scales then lets you weigh a first meal. Above 20 °C for a sustained period, the colour-enhancing food is more suitable, while below 12 °C the floating wheatgerm food takes over. All three can be found in the pond fish food collection.

Water temperature and storage

Do not confuse the air temperature with the temperature of your pond water, because it is the latter that counts, and it should be measured in the morning. Do not keep the summer ration going above 25 °C, as warm water holds less oxygen. Do not keep an opened bag from one year to the next, as the fats oxidise as soon as it is opened. And never feed this food to ruminants or to any other animal species, as the label reminds you, because it contains fish meal.

📏 Choosing the gauge and format

Choose the pellet size according to the smallest fish in the pond, not the largest. Size S suits fish under about fifteen centimetres and mixed ponds where several generations live together, while M is for a uniform adult population, and L, at 6 to 7 mm, is for large koi over 25 cm. A pellet that is too big leaves the smaller fish out of the meal without anything showing it, since the big ones eat for everyone. As for pack size, choose by how long you will take to use it rather than by the price on the label: an opened bag loses its qualities within a few months, so a large pack is only worthwhile in a pond that empties it before the end of the season.

🐟 Feed and nitrogen load

Everything you feed ends up in the water in one form or another. What the fish absorb comes out as ammonium through the gills, what they do not absorb comes out as solid waste, and what they do not eat breaks down on the bottom. A ration increased by a third therefore means a nitrogen load increased by the same amount, whether or not your filtration can absorb it. In an ornamental pond, this shows first in the clarity of the water and in a surge of filamentous algae. In aquaponics, the same quantity becomes the fertiliser for your crops, which completely changes how you read it: the ration is set there by the planted area as much as by the fishes' appetite, and the article on the nitrogen cycle explains this sharing in detail.

Which All Seasons pack size to choose

It is the same feed in all six cases: only the period covered and the way the stock ages change. The durations assume a ration of 2% of body weight per day.

From 0.5 to 10 kg: which one gets used up before it goes stale? An open bag absorbs moisture. The right size is the one your fish finish before the end of the season, given the conditions in which you store it.

Frequently asked questions

8 questions

6 key questions, 8 in the detailed view

Which pack size should you choose, from the 0.5 kg sachet to the 10 kg bulk pack?

All of them contain exactly the same feed. What changes is the length of time covered and how the stock ages.

Pack size	Sealed bags	For 10 kg of fish	What sets it apart
0.5 kg	1	about 3 days	Trying the feed
2 kg	1	about 10 days	Small pond
5 kg	1	about 25 days	The standard size
6 kg	3 of 2 kg	about 30 days	Two bags stay sealed
9.5 kg	1	about 48 days	The large bag, in large, or in medium to order
10 kg	2 of 5 kg	about 50 days	The lowest price per kilo

The pack of three 2 kg bags is the one to choose to keep two bags sealed while the first is being used up, the pack of two 5 kg bags for the price per kilo. Durations are calculated at 2% of body weight per day.

From what water temperature can this food be given?

How much feed should you give per day?

5 minmaximum length of a feed

1.5 to 2%of body weight per day

The minutes rule takes priority, because it adjusts itself to the temperature and to the day's appetite. The percentage also depends on age, as a one-year-old fish can eat up to 5% of its weight per day in warm water, whereas a three-year-old eats only about 2%. Use a net to remove any pellets still floating after 5 minutes.

Small, medium or large: which size to choose?

Small, 2 to 3 mm: suitable for fish of around 7 cm and over, goldfish and young koi, in 2 or 5 kg bags.

Medium, 4 to 5 mm: suitable for fish of around fifteen centimetres and over, from the 0.5 kg bag to the 10 kg lot, the 9.5 kg bag being prepared to order.

Large, 6 to 7 mm: intended for koi over 25 cm, in 2, 5 or 9.5 kg bags. A pellet that is too large gets spat out, while one that is too small forces the fish to take many more mouthfuls and makes the ration impossible to judge by eye.

How much ammonium does this feed produce compared with the others?

For every 100 g fed over the day, the four foods compare as follows:

Food	Protein	Ammoniacal nitrogen per day, as NH4
Floating wheatgerm food	32%	3.3 g
This one	33.5%	3.4 g
Colour-enhancing food	39.5%	4.1 g
Sinking sturgeon food	47%	4.8 g

In 10 m³, 3.4 g per day makes 0.34 mg/L if the filter treated none of it, a value expressed as NH4, like the one read by an ammonium test. The calculation assumes that half of the nitrogen in the food is released into the water, which makes it an upper estimate in a planted pond.

What should you do with the bag when the fish stop begging for food in autumn?

Reduce the frequency before the quantity: two meals a day between 12 and 18 °C, only one below that.
Below 12 °C, finish the bag by cutting back, then switch to floating wheatgerm, one to three times a week.
Below 8 °C, stop feeding altogether and let your fish live off their reserves.
Store the remaining bag somewhere dry and shaded, and judge it by its smell in spring rather than by its date.
Resume when the water has settled back above 10 °C, starting gently.

How long does an opened bag keep?

Does it contain spirulina, krill or a pigment for colour?

Estimate the daily ration for your fish

Enter the total biomass of your fish, that is, the sum of their weights. The calculation uses 1% of the biomass per day, the commonly published guideline for water at 15 to 18 °C. Double it at around 21 to 23 °C, and use the result as a starting point to be weighed out once.

Total biomass of your fish

1 kg80 kg

0g per day

Total daily ration, to be split into several small meals, for water at 15 to 18 °C.

Consumption over a full month at this ration

0 kg per month

The 1% factor is an industry guideline, consistent with the 1.5 to 2% of biomass published by the FAO for Cyprinus carpio in ponds. It applies to adult fish, as a one-year-old fish eats more. The overriding rule remains to give only what is eaten in under five minutes.
