Seachem Acid Regulator

Acid Regulator™ adjusts pH to the acidic range (4.5–5.5) and softens water by precipitating calcium and magnesium. Acid Regulator™ supports the establishment of the optimal environment for all acid acclimated species (e.g. neons and other tetras, etc.). For further freshwater environment enhancement, use Fresh Trace™ to restore the proper level of trace elements and feed NutriDiet® Tropical Flakes for thriving, healthy freshwater community fish.

Contains phosphate buffers and conditioning agents. Safe for all freshwater fish acclimated to acid pH.

Directions

Use 1 level teaspoon (5 g) for every 40 L (10 US gallons) daily until intended pH is reached. For precise dosing use the Seachem Digital Spoon Scale. Thereafter, use once a month or with water changes as required to maintain pH. To raise pH, use Neutral Regulator®.

To target a particular pH use in combination with Neutral Regulator® following the chart. This chart assumes the use of unbuffered water (RO or DI). If water is already buffered use the chart as a starting guide. Use Prime® to dechlorinate tap water before doing a water change.

To target a particular pH use in combination with Neutral Regulator® following the chart

Neutral Regulator Acid Regulator pH

1 2 6.4
1 3 6.2
1 4 6.1
1 6 6.0
1 9 5.8

 

A: Yes, it won't harm your plants, however, Acid Regulator™ is a phosphate based buffer, so you may experience some unwanted algae growth depending on usage. For lowering pH in the planted aquarium, we recommend Acid Buffer™. Acid Buffer™ is a phosphate/carbonate free buffer for lowering and stabilizing pH in the acid range of pH 4–6.8.

A: The difference is that Acid Buffer™ is a straight acid source and Acid Regulator™ is a phosphate based buffering system. Acid Regulator™ has a greater ability to maintain a pH as were a straight acid source can have a slight pH drift. When you are trying to avoid any additional phosphates I would go with the Acid Buffer™ and Alkaline Buffer® products but if that is not an issue, then the Acid Regulator™ will maintain a more constant pH.

A: You can use Acid Regulator™ by itself to achieve a pH within the range of 4.5 - 6.8, adding slowly until intended pH is reached. We recommend using Acid Regulator™ in combination with Neutral Regulator® or Alkaline Regulator™ to maintain a slightly higher pH or to increase pH (if your pH is lowered too quickly, etc.).

Won’t buy again
Size: Tripod, Size: Tripod
It started out great. But then it came apart and my puppy almost swallowed the piece that makes noise. Otherwise, it’s been a good brand of bones. Just not this particular one. The end unscrews and came apart. Not great!

Not for super aggressive chewers
Size: Tripod
Had high hopes, but our super-chewer somehow manages to UNSCREW the ends of the toy. Had to throw it out so she wouldn’t choke

Great Chew Toy
Size: Tripod
Has been great for our medium sized dog who loves to chew everything. We didn't realize it makes a sound too, which helps keep his attention. So far it has held up well.
