Thomas ★★★★★ Oct 20, 2026

Noticed a real difference in my sword plants after just a few doses—the leaves look deeper green and new growth is coming in strong. The liquid mixes clear and doesn't cloud the tank at all.

My crypts went from melting to sending out new runners within a couple weeks, and the micro-trace blend is clearly doing its job. Calcium and magnesium in the bottle mean I don't have to dose separately, which saves me a step. This stuff's earned a permanent spot on my shelf.

My java fern was looking pretty sad, but after a few weeks of using this supplement, I can already see new green growth and the leaves look much richer. The fact that it includes calcium and magnesium is exactly what my tank needed.
