Hey there. I wonder if I can use calcium supplement without the buffer part. I noticed the store sell it together and its recommended, but I don't wanna mess with my alc, its stable with red sea buffer.
If you already have it, I'd use both parts of the B-ionic equally to maintain alkalinity, and calcium will follow along.
If you really want to, you can use the B-ionic calcium part and the Red Sea buffer, but that is wasting the advantage of a two part, which is balanced calcium and alk dosing. You can't buy the calcium part alone anyway, I don't think.
