Q: I have a planted tank with neons. I want to lower my pH. Can I use Acid Regulator with my plants?
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 reccomend Acid Buffer. Acid Buffer is a phosphate/carbonate free buffer for lowering and stabilizing pH in the acid range of pH 4–6.8.
Q: What is the difference between "Acid Buffer" and the new "Acid Regulator" pHconditioners that your offer? 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.
Q: I've been using the Neutral Regulator with Discus Buffer to hold to around a 7.0 PH. Having just seen and ordered the Acid Regulator I assumed I could use it alone to keep a 6.8 or so pending how much I use. Is this true or do I need to keep using the Neutral with it? And if so what's the difference between the Acid Regulator and the Discus Buffer then?
A: The components of Acid Regulator and Discus Buffer are similar so both can be used successfully in your system. 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 slight higher pH or to increase pH (if your pH is lowered to quickly, etc).
