For over three decades, Seachem has been a company rooted in sound science. Our experience in the hobby and an educated staff of chemists and biologists are part of the package when you purchase Seachem products. Seachem remains as one of the few surviving independent and privately owned pet care companies. Seachem is owned and operated by hobbyists. All of our employees are hobbyists who maintain aquariums at home and at the office. Seachem itself was started because one such passionate hobbyist – Dr. Leo G. Morin (Founder) – recognized that the available solutions to aquarists problem wanting. This resulted in Seachem’s very first product: Cupraplex (today known as Cupramine). Over thirty years later Seachem is still approaching old problems in a new way.
Seachem’s philosophy is that the knowledgeable hobbyist makes the best customer. This is reflected in solid and reliable customer education and support as well as products proven in science and performance. While Seachem has grown rapidly into a national and international firm, it retains the culture of a small company and is readily available to its customers.

Seachem Neutral Regulator- Neutralizes pH Levels for Freshwater Aquariums
NEUTRALIZES PH: Neutral Regulator adjusts pH to neutral (pH 7.0) from either a low or high pH and maintains it there
SOFTENS WATER: Seachem’s Neutral Regulator softens water by precipitating calcium and magnesium while removing any chlorine, chloramine, and detoxifying ammonia
OPTIMAL PERFORMANCE: To lower pH below 7.0 use the Neutral Regulator with Seachem’s Acid Regulator or Discus Buffer. To raise pH above 7.0 use with Seachem’s Alkaline Regulator
TANK USE: Use 5 g (1 level teaspoon) for every 40–80 L (10–20 US gallons) once or twice a month (or as necessary to maintain a pH of 7.0.) Neutral Regulator may be initially used daily in cases of high alkalinity until 7.0 is established

I really like this product
I really like this product. I have a small 20 gal tank. I have very hard water at home. I have been using PH down to maintain, but I like this much better. It kind of bothered me the first time I used it and the tank clouded up. All was fine within a few minutes and It works great for me.

Good for hard municipal water
Used as an all in one product when doing water changes on my tank. I cant always get to an RO machine but this works pretty well as a substitute. It lowers the acidity, and dechlorinates my crap tap water… so well that I’ve used it on my plants in a bind as well. A plus is that you dont need any other conditioners. Seachem products can be a little expensive, but they’ve not let me down. Good stuff.

Works as expected
When you do a water change…dump the powder as per directions in the new pail of water..changes ph to 7…the best

I love seachem products
I could have used ph down. same outcome – but a fraction of the price. I capful treats 2.5 gallons – so I used the entire bottle for my 120 gallon. It brought my 7.4 ph down to 7.0 and within 24 hours it was back up to 7.4 and my new blue rams didn’t adjust (they prefer softer water than 7 – but I chose the regulator bc it would stabilize the ph – but it didn’t). I love seachem products… but this one failed me, and my fish.

Missing seal on the bottle i received
The product serms to work good. When it arrived some of it had leaked out and when I opened the bottle i found that the seal was completely missing. So I paid for a full 250ml bottle and only received probably about 100-150ml. I know Seachem always seals their products, I’ve used their products for years. Frankly I’m disappointed ð

You need to use a fair amount (Iâve just a 60 litre tank) and it helped raise just a little from 6.5 to perhaps 6.8 PH.Perhaps I wasnât using it correctly and I wouldnât say a waste of money, it didnât affect my fishâs health atall or the water quality so I was super pleased about that.
