I guess this device doesn't consider rinsing out the frozen before feeding. I was always told that frozen food contains phosphates from preservatives.

I produce Ocean Fresh Pacifica Plankton. I do not add any phosphates, preservatives or stabilizers, water or other fillers. The food is 100% pure Pacifica plankton frozen live on the fishing boat at time of harvest. I process and package it in the frozen state. It is kept frozen until you thaw it out to feed. The food is amazing.

For those interested in rare wrasses there is one in the picture at the bottom of the page. It's not a Fairy wrasse either. :)
