buffer question ?

[Adam Rasmussen]

i was wondering the best way to buffer alkalinity

last week it was at 3.5 mil/eq and this week its at 2.75

Plenty of ways to add buffer. baking soda is the cheapest way. go to the chemistry forum and read up on Randys two part CA / ALK (home made mix) works great.

That article should be useful. For getting started, some B-Ionic or Kent Tech-CB would be a fine choice. You can make your own if that works well for you.

IMO, you should choose a calcium and alkalinity supplement that's less problem-prone than baking soda.
