I feel like having nutrients always available for the corals is a good thing. My thought is to always have food available so that nothing ever starves.
I’d much rather waste a bit of money on food then starve things in the tank and not get any growth.
I have 10 fish in a system with only 50 gallons of water in it. All of the large pieces of food get eaten, and the ones that don’t get eaten by my two cleaner shrimps or by the massive army of mini brittle stars I have.
All the little bits get sucked up by the corals and sponge in the tank.
Whatever is left is exported by the skimmer and scrubber.
It’s a balance. I only spend maybe $10 per month on food max.
All I’m saying is that this is by far the best growing tank I’ve ever had, and the only one I’ve ever fed more than once a day.
