Yes I know this product but I never used it because not needed it. I want to keep freshwater hobby as simple as possible. I even find these instructions complicated on that page about how to use it:
"Use 6 g (one level teaspoon) for each 40 to 80 L (10 to 20 US gallons) of water each day until desired pH is attained and maintained. Thereafter, use as required to maintain pH, usually no more than once every two to three weeks. For precise dosing, use the Seachem Digital Spoon Scale. TIPS: It is best to dissolve the buffer in freshwater before use. Use when setting up an aquarium or making water changes (preferably after the addition of Seachem's Cichlid Lake SaltTM) and between water changes as needed to maintain pH. Seachem's Malawi/Victoria BufferTM is formulated to maintain a pH between 7.8 and 8.4, depending on the amount used. To attain a lower pH than 7.8, you may use Seachem's Acid BufferTM in combination with Malawi/Victoria BufferTM. To attain a higher pH than 8.4, use Tanganyika BufferTM"
To me this is complicated because it is time consuming. I would need to prepare the water to the same ph as my tank in advance before changing water and not to mention the water that evaporates with time. If your tank has a lid then its great but if not then there will be lots of water evaporation and when water evaporates, the chemicals added stays in the water resulting in high ph and you ll need to add RO or distilled water to make up for that evaporation. If you are up for this challenge then yes sure go ahead.
Personally, I would never risk my 1000 dollars fish by adding chemicals to attain ph I want. I would go for some other route like crushed coral or something which is guaranteed to offer me a stable ph at least. But my best option is to let the water as it is. Add fish and enjoy watching them and since you already have high quality premium foods they would show very vibrant colors for sure.
