MICROBE-LIFT Sinking Fish Food Pellets for Ponds, Water Gardens, and Fountains, for Live Goldfish and Koi, 14 Ounces

It was tough to find good high quality sinking food for those koi and hi-fin sharks in my pond that won't come to the surface. Most koi food seems to be the floating type. I actually mix this in with some floating food and get a 50/50 mix. That way the bottom loving fish can still get their fill too. Now my pond is a swimming pool for fish so I don't have rocks or plants in the bottom. This mean sinking food does get all eaten. Another positive point is this food did not cloud the water at all - of course it never lasted that long anyway since the fish really liked the flavor. You might want to keep that in mind if you get this food since if you have rocks or plants sinking food might not be best. Still, I like the ingredients and high quality of this food and will be ordering more.

I am so glad to find a bit larger size fish food that does sink. The first few days I had to break them smaller to convince my fish that they are food (the former pellets were tiny), but now they eat them. Turtle loves them too... My goldfish are 4-6" tip to tail.

This food has been valuable in feeding one of our koi that has trouble getting to the surface to eat. I have had no problem with it sinking to the bottom when I soak it in a jar of water for five minutes before feeding. My other koi enjoy it also, once they have finished their floating food and after the compromised koi has had his fill. No problems with it clouding my pond's water, either.

My koi and goldfish seem to like it. Most of the first handful I threw into the pond floated across the water surface into the filter. Now I either throw it with force onto the pond surface, toss it on the special spot where the water swirls a long time, or toss it in under the waterfall so it will sink.

I originally purchased floating fish pellet food (different brand) which quickly made me realize that was a bad idea with a water level skimmer that quickly gobbles up the fish food before the fish have time to eat it. To get around this I had to shut off the pump which was a pain in the butt cause half the time I would forget to turn it back on. Low and behold I see on Amazon they sell SINKING fish pellets specific for my type of pond set up...genius! Well at least I thought so right up until the new fish pellets arrived and I used them for the first time. Low and behold the SINKING fish pellets did not sink (at all), not a single pellet fell to the bottom of the pond, not even after 5-10 min of sitting in the water! How do you sell something advertised as a SINKING pellet that does not sink! Big waste of money and time waiting for this fish food to arrive for it to completely fail its intended purpose. I guess now I have plenty of FLOATING fish pellets to last me a while.

I just added two smaller koi. One was very shy for the longest time and would not feed with the bigger koi. I got this sinking food because it was smaller than the floating food that I usually feed my fish and I doubt that the smaller fish would be able to it it. Plus, since it sinks I could put it so it would sink right by its hiding place so it would come and eat. The other fish eventually caught on and would race over to eat this food instead of their regular food so I have to put it in different places. Now the smaller fish are used to their environment and have joined the others to feed. But I’m still feeding them this food to encourage growth. I’m sure it’s working as I can’t believe how fast they’ve grown. And the colors of all fish also seem to be enhanced. Good product but a bit pricey. But you pay for quality.

The pellets really do sink, and my koi loved it!

Normally I use floating koi food so I can see the fish come up. I have one koi who was injured recently and is missing most of her tail. She can't get to the top so this food was very helpful. Unfortunately they all like it so they try to get to it before she does. I have to be clever and divert them elsewhere as much as possible. But it really helps to keep that fish fed so she can recover
