FAQ: Is it possible to overdose Seachem Reef Phytoplankton™?

Any product, even plain RO/DI water, can be overdosed to the point of stressing fish. A large overdose of Reef Phytoplankton™ all at once is needed in order to see any ill effects in the aquarium, but we still recommend following the dosing instructions as closely as possible as a general rule.  The likely impact of a very large overdose would be a bacteria bloom (haziness in the water) that typically clears after a few days as well as a dip in pH.
