What are you dosing on top of All For Reef?

[Reef Puncher]

If the goal of the AFR is adding trace elements, then it can be accomplished more cheaply with a trace element mix (such as TM A and K) plus the kalkwasser.

i thought about that. one thing i like about the all for reef is how long it lasts, and how little it takes to bring up alk/calc. like 15 ml a day? kalk i needed like 290mls a day. is the alk they use that much more concentrated or something?
