What to check before you add it
The adjuster suits both freshwater and saltwater systems, so a marine tank is covered as well as a community freshwater one. It is made to work alongside pH stabilizers, which means a tank already running a stabilizer can still take this liquid.
One bottle covers up to 2,800 gallons, so a single 16 fl oz unit goes a long way on larger systems. If your total water volume is above 2,800 gallons, one bottle will not cover the whole volume.
What reviewers report after dosing
Some reviewers say they saw no change in pH after using the product, and others mention that the reading climbed back up again afterwards. A smaller group reports that fish died following use. Those accounts are worth reading alongside the stated function of lowering pH gradually.
What the 16 fl oz pack contains
- One bottle holding 16 fl oz (473 ml) of liquid adjuster
- A cap for the bottle
How the liquid adjuster behaves in a tank
The adjuster lowers pH levels gradually rather than all at once, and its effect is to push the water toward the acidic side. Because it arrives as a liquid, it goes into the tank in that form straight from the bottle.
The bottle measures 5.7 x 5.7 x 21.6 cm (2.2 x 2.2 x 8.5 in) and weighs 454 g (1 lb). Its clear body lets you see how much liquid is left.
