DIY fish food can be made for a really low cost with a blend of items by using frozen mixed bags of food. I made up about 1/2 gallon of fish food using these blends plus PE mysis, blood worms, and brine shrimp for around $30. However, the frozen mixed bags contain sodium tripolyphosphate as a preservative. Does anyone use homemade fish foods containing this preservative? Is there any scientific evidence that this preservative is harmful?
If not harmful, is there any evidence that there is a higher phosphate level in these food blends than in other blends? If higher phosphate is the only problem, I can up my phosphate export methods and still save money in the long run. Thoughts?
