I mix different types of frozen together and then keep it in the fridge. I use a syringe to extract just what I want to feed and then it gives me very granular control on how much I put in at a time. I can then watch the fish and ensure it is all eaten before I add more. Previously on this size tank I would likely have thrown in 2 frozen cubes per day + pellets and had a snow globe effect. Now 2 cubes is lasting me a week at a time using this method. No wonder I had such horrible problems with algae and coral growth in general before. I have had the past 18 months to practice this feeding method on my JBJ 30 to good effect.
