Just got the TMC Tropic Marin Pro Cichlid Mineflake 500g, supposed to be good for 1200l.
Malawi & Tanganjika flour, that's what it's called.

I bought it to increase the PH and water hardness in my tank.
Was it worth the money?

Bicarbonate soda also raises pH levels, you can crush shells or use cichlid flake substrate as alternatives, and they might even be more budget-friendly.
