When I started keeping koi thirty years ago, I fed them the same pond sticks and flakes everyone else used. They ate well enough, or so I thought. It was only when I switched to floating pellets that I understood what I had been missing. My pond cleared up within a fortnight. My fish grew faster, coloured up more deeply, and began coming to my hand to feed within a few weeks. The difference was not subtle.
If you are still reaching for the flakes or dropping in sticks, this is worth reading. These are the ten reasons experienced pond keepers almost universally make the switch, and why so few of them ever go back.
Still watching your fish hunt sinking sticks along the bottom? There is a better way.
CrystalClear Staple pellets float at the surface so you can see exactly how much your fish eat, when they eat it, and whether their appetite is changing. Over 865 pond keepers have tried them. Most reorder within the month.

Flakes and sticks sink. Once they are below the surface, you have no idea whether your fish ate them or whether they are dissolving into the water and fouling your filter. Floating pellets stay right where you put them. I can count every pellet my fish leave uneaten and net them out before they break down. After thirty years, I consider this the single most important reason to switch. A pond keeper who cannot see the feeding is flying blind.
Uneaten food does not cloud your water
Dissolved flakes and waterlogged sticks are one of the leading causes of green, murky pond water. They release phosphates and nitrates that feed algae. Because floating pellets stay at the surface, you can remove whatever your fish ignore before it ever breaks down. My water clarity improved noticeably within two weeks of switching, and I had not changed my filtration at all.
Pellets are far easier on your filter
Everything that is not eaten eventually reaches your biological filter, where bacteria have to process it. Whole floating pellets that you remove from the surface put almost nothing into that cycle. Crumbled flakes that dissolve on contact put a great deal in. Your filter will thank you, and so will your water readings. Less ammonia, less nitrite, less work.
You can monitor your fish's health at every feeding
Koi that come to the surface for floating pellets give you a close look at their scales, eyes, fins, and behaviour twice a day. Fish that root around the bottom for sinking food are harder to inspect. I have caught early signs of ich, fin rot, and dropsy this way, each time early enough to treat successfully. Feeding time becomes a health check.
Floating pellets are gentler on the digestive system
Koi are not designed to swim headfirst to the bottom and gulp air as they pick up food. Repeated feeding from the substrate forces them to ingest air, which can contribute to swim bladder issues over time. Floating pellets keep feeding at the surface, where koi naturally graze. CrystalClear Staple pellets are specifically formulated for easy digestion, which matters a great deal during the warmer months when fish metabolism is at its peak.
Feeding time used to be something I did without thinking. Now it is the quietest, most satisfying part of my gardening day.
Pellets have a higher, more consistent protein content
Flakes are made by extruding a paste over high heat and then drying it in thin layers. A great deal of nutritional value is lost in that process. Pellets are also extruded, but their larger, denser structure means the protein and vitamin content stays more stable from batch to batch. CrystalClear Staple is packed with protein to support summer growth, and the formulation does not change depending on which corner of the bag you scoop from.
Floating pellets tame overfeeding
With flakes, it is terribly easy to shake out too much. By the time you realise it, half the flakes are already below the surface and on their way to your filter. With pellets, you count them. Literally. I feed my fish roughly thirty pellets per koi per meal during summer. If they stop eating before they finish, I know something is off. That control is impossible with flakes.
Hand-feeding becomes genuinely possible
Koi that learn to take floating pellets from the surface will, given a few patient weeks, take them from your hand. This is one of the great pleasures of keeping pond fish, and it simply does not happen with flakes or sticks in the same way. My oldest fish, a kohaku named Margaret who is twelve years old and roughly 60 cm long, has been hand-fed every morning for six years. That relationship begins with floating food.
Colour development improves noticeably over a season
A quality floating pellet formulated for koi contains the carotenoids and spirulina extracts that deepen orange, red, and white colouration. Generic flakes rarely include these at meaningful concentrations. I photographed my showa koi at the start of last summer and again in September, using the same light and the same spot on the pond edge. The contrast was striking. Whether you are keeping fish for pleasure or for showing, colour matters.
Storage is simpler and the food stays fresh longer
Flakes crush. Once the bag is opened, they absorb moisture and start to degrade within weeks. A good pellet in a resealable bag keeps its shape, its nutritional profile, and its palatability for the full season. CrystalClear Staple comes in a 2.2-pound bag that I find lasts a full summer for a pond of six adult koi. No waste, no clumping, no guessing whether the food at the bottom of the tub is still any good.
What I Would Skip
Not every floating pellet is worth the shelf space. I have tried several over the years that floated beautifully but left a greasy film on the water surface, broke apart too quickly in warmer temperatures, or had a smell that put the fish off for the first few feedings. One brand I trialled three summers ago produced noticeably cloudier water despite my fish eating every pellet, which told me the formulation was releasing too much into the water column on contact. Do look at the protein percentage on the bag, check that the pellet size suits your fish, and give a new food a solid two-week trial before drawing conclusions.
I have settled on CrystalClear Staple as my warm-weather staple because it holds together well even after several minutes on the surface, my fish take to it immediately, and my water quality numbers have stayed consistent across two full seasons of use. At 4.5 stars from over 865 reviews on Amazon, it is clearly not just my fish that agree.
If you want to try floating pellets with a brand that has a genuine track record, CrystalClear Staple is a sensible place to start.
Your fish will come to the surface. You will be able to see them clearly, watch them feed, and remove anything they leave behind. It is a small change that makes a real difference to both the pond and the pleasure of keeping it.
