## Description

Seachem Acid Buffer 300gram

Review: This works where others don't! Problem PH too high? Use this! - If you have high aquarium PH and it keeps bouncing back after using a PH lowering product, try this. It worked for me after bottles of PH Down, salts, and PH neutral powders. You don't need much, but you will see a difference quickly. It does not cloud the water and when added in prescribed amounts has not affected my fish, they are safe. It works pretty quickly, though not as fast as the direct PH Down - but the PH stays down. This is a good value and this brand is a well known supplier you can trust. They also offer a PH Up powder that works in similar, but reverse fashion.
Review: Helps establish good water parameters - A must for Discus tanks.

## Questions & Answers

**Q: Will this keep the ph at 7.0**
A: Yes and no.  Seachem has three products, the acid buffer, alkaline buffer, and neutral regulator.  Neutral regulator is phosphate based so be careful using in planted tank.  However, if that is not a concern than neutral regulator is probably more what you are looking for to keep pH at 7.0.  There are very specific instructions as to how to use all three to get the desired pH for what your fish prefers.  It also depends on the hardness of your water.  I use acid buffer to maintain pH below 7.0 as that is what my shrimp prefers.  That being said, however you adjust it, do it slowly.  Fish don’t do well with big swings.

**Q: What kind of acid is the ingredient?  Is it citric acid?**
A: No! It is a sulphate salt that will not increase the phosphates in your planted aquarium. It is less stable meaning that has a shorter life in contrast to the phosphate salts but it helps you reach the lower pH with no problems. Remember to do pH changes gradually to avoid stressing (killing) your fish. It is excellent for planted aquariums.

**Q: My local tap water is above 8.4ph according to my tests. How would I properly use this product for water changes and the intial treatment of my tank?**
A: Pour a measured amount, ie 1 gallon in a pitcher and add a teaspoon of acid buffer, mix and measure pH. The once a recipe is known to convert tap water pH to desire levels, then scale up in your tank

**Q: My tap has a ridiculously high kh, if i use this will it remove kh indefinitely w/o need to dose the tank again just replacement waterduringh20change?**
A: You will need to continuously dose in order to maintain it.
