Seachem Eq vs GH booster

[JoshP]

I have read on here that Seachem Equilibrium isn't trace, but a GH booster. Would a GH booster such as Rex Griggs booster or similar be interchangeable with equilibrium?

 

[rusticitas]

Barr's GH Booster and Seachem's Equilibrium are practically equivalent. They were designed to only increase General Hardness. Minerals, not traces (or micros). You will want something like CSM+B, Seachem's Flourish, or Tropica's Plant Nutrition (formerly known as "Mastergrow").

GH boosters, Rex or AF's are modified from Seachem's formula.

Generally, a bit more Mg, less K+(there's plenty).
