Water Quality and Movement
To raise healthy aquatic animals, water quality—and especially proper levels of ammonia, alkalinity and carbon dioxide (CO2)—must be monitored and maintained.
Pentair Aquatic Eco-Systems has scientific and engineering experts to help solve your water-quality and movement challenges.

We Can Help You Learn About Key Water-Quality Measurements
Aquaculture operators of all sizes, from hobbyists to large-scale farmers, can find themselves challenged by water-quality issues that directly impact the well-being of their fish stock.
Our team of scientists and specialists at Pentair Aquatic Eco-Systems can help you identify and troubleshoot all of your issues regarding aquaculture water quality management.
Hatchlings Depend on Correct Calcium Concentration
Hard water causes scale deposits after it evaporates, clogging pipes and air diffusers. Hardness depends mostly on the concentration of calcium and magnesium ion. It’s particularly important to newly hatched fish that obtain much of their calcium directly from the water.
Generally, freshwater fish do best when hardness is maintained near 100 mg/liter. Based on your water-test results, our team of experts can provide you with recommendations to raise or lower the hardness level of your water.

Test, Adjust Total Ammonia Nitrogen Level
After oxygen, the amount of ammonia is the most important water-quality parameter affecting fish. Ammonia, a natural byproduct of fish metabolism, causes stress and damages gills and other tissues. Fish exposed to low levels of ammonia are more susceptible to bacterial infections, and they grow slowly. Ammonia can kill in high concentrations. Because ammonia is continuously excreted by fish through their gills, successful aquaculture operations must incorporate methods to detect and eliminate ammonia before it can accumulate and harm fish stock.
Investing in a water-quality test kit is a good first step. Most commercial ammonia test kits measure the total ammonia nitrogen (TAN). Our experts can provide you with recommendations for steps to take to quickly lower ammonia levels in urgent situations and to manage ammonia levels properly over the long term.
Sparus™ Pump With Constant Flow Technology™
Our Sparus™ pump with Constant Flow Technology™ offers the highest water flow rate of any high-performance pump—with the lowest electricity consumption—and automatically calculates and self-adjusts, to provide the exact speed needed to deliver the exact flow rate that you establish.Learn more
Carefully Test, Monitor Water Alkalinity
Alkalinity is the buffering capacity of water—its ability to maintain a pH of 7.0 or above. Alkalinity should not fall below 80 mg/L as CaCO3. To increase alkalinity, add sodium bicarbonate. Our team of experts can provide you with recommendations to raise or lower the alkalinity of your water, based on your test results.
Point Four™ RIU3 Remote Water Monitor/Controller
This remote interface unit (RIU) is a single-sensor transmitter/controller that accepts inputs from any sensor providing a voltage, 4-20mA or thermistor input. Equipped with an optional backlit display, it allows the user to view readings remotely. The RIU will function as a stand-alone controller; or up to 10 units can be daisy-chained for a network connection.Learn more
