Seachem Alkaline Buffer 600gram

Dissolves quickly. Works great.

Works wonders!

Does nice job to achieve proper alkalinity in RO/DI water. Good value.

Not much to say here it works well and is cheaper in the large size. add this first before the euilibrium if you are replenishing RO to a specific tds. this one dissolves much quicker.

My tap water has a very low KH (1d) and a reasonably high pH (7.5). Because of this the pH can be unstable in my 125 litre community tank. I use the Alkaline Buffer along with the Acid Buffer to raise my KH by 2 or 3 degrees without affecting my pH. The Buffers are easy to use and last for quite a while, depending on what tub size you go for. All of my fish, including the sensitive German Blue Rams, are happy and healthy.

I have been raising mystery snail babies and the bioload from so many in one tank was making the pH plummet. Which is horrible for their shells. I tried a pH+ liquid that did nothing. Then I saw a recommendation for this stuff and I was desperate. One little scoop of this in their tank and the pH and KH went up! What a life saver this was for my snail babies last month at home before going off to find new homes. I’m using this in my other tanks now too. Amazing product and boosts that pH within minutes!!!!

This worked great. We have well water & the PH is low. There was no way to change my PH in my aquarium without this. Definitely worth the money to have happy & healthy fish.

Arrived in one piece.
