I have a lot of little squeeze bottles like small sauce bottles, but before I use them I make up foods, including all that I can find of planktonic and small shrimp species frozen life from the lfs and small krill and lobster eggs, I put the last two to one side, then blend up cunjevoi ,limpet meat and green muscles or you could just use green muscle meat, never use predator meats, then a quicker blend including the krill and lobster eggs, then I add all the small shrimp species and planktonic frozen stuff and mix.
I make up around 60 litres to last a couple of years of it in saltwater with a lot of pure salt to prevent bacteria build up if when I thaw it and put into aquarium shop bags or freezer bags into my freezer.
Then one bag I take out and thaw, then I sive threw small holed aquarium net and what goes through goes in one bowl and the goes in another bowl, I fill to top with saltwater and add more pure salt and a little amino acids and then I have 8 squeeze bottles with f written on top for fish food, that's for the not so fine foods and the other 8 bottles I have an I written on them for invert foods being very fine food particles.
I fill the bottles with a funnel and make sure I stir the bowl each time I fill a bottle from the bowl.
Then I freeze the bottles and thaw as I need one, I have one I and one F at any one time to use, then just squirt into the water from the top of the water from 4 to 20 tim4es per day and they last two days with no refrigeration but 5 days in the fridge with no detrimental bacteria developing in those bottles.
I always leave out a day each week with no feeding! Gives the water and bio media a rest and fish get use to it.
I have always done mine this way, but the squeeze bottles, just the last 7 years, no way I would do it any other way.
