Faith Greene –
Used this in my reef tank for several months. My soft corals have shown better coloration and growth. The liquid is easy to mix and stays stable without needing refrigeration. A reliable supplement for daily use.
Gavin Metcalfe –
Good for maintaining invertebrate health. The phytoplankton cells are visible under the microscope and seem to support my tube worms and sponges. Slight improvement in coloration after consistent use.
Rachel Jones –
Highly effective for larval invertebrates. The amino acid addition helps with color development. No issues with storage or mixing. I’ve used it for over three months with no changes in consistency or performance.
