This chart includes water conditions for both Reef and FOWLR (Fish Only With Live Rock) systems. These are guidelines for fish typically found in these types of aquariums. Some species have very specific needs, so please be aware of these and make the necessary adjustments.
We offer a variety of Test Kits, as well as Supplies and Additives, that can help you maintain proper water parameters. Note: the abbreviation (ppm) stands for Parts Per Millionth.
