I have a 2.5 quart bucket of really nice African cichlid buffer for sale. This is from Cichlid Exchange in Oregon. I no longer have my Hap tank running, so won't be needing it. But I can say from personal experience that this is a great buffer. Holds your water at 8.1-8.3 very reliably. This amount would last several months on a 150g tank with weekly 60% water changes. $15.
