Feeding scrubber growth to fish

[SantaMonica Verified Sponsor]

The great thing about a scrubber is that it grows exactly what many fish eat naturally. Even fish that you think would not eat algae, such as some cichlids, will do so if the growth is living. But many freshwater and saltwater fish and other animals love it. Green hair algae especially, but also some of the lighter brown slimes.

It's similar to a garden, where you eat the growth, then compost the waste which grows new growth, so you can buy less food. Same with algae scrubbers in aquariums; the more you feed from your scrubber, and the less food you add from the outside, the lower the nitrate and phosphate will be in the water.

Some people think that if you don't remove the scrubber growth and throw it away, you won't remove nutrients from the water and the nitrate and phosphate will increase. But the answer is to add less food from the outside, and replace it with the fresh living growth from the scrubber. Nutrients will flow from the fish to the scrubber and back to the fish, and the fish will use those nutrients to grow bigger, which takes those nutrients out of the water. And since you are adding less food (nutrients) from the outside, the nutrients (nitrate and phosphate) in the water goes down to a lower overall level.

How do you feed scrubber growth to your fish? Well with any scrubber, you can remove the growth with your hand if the growth is green hair algae; then you can put the growth in the water or use a feeding clip. If you have certain bubble upflow models, you can put the whole thing in for the fish to eat from it. If you have a waterfall model, you can put the screen into the water, or you can remove the growth from the screen first.

I can vouch for my surf 4x producing a nice supply of tang food. I haven't bought nori since it started producing.
I get this amount every 5-7 days.
