DYMAX Instant Start 500ml is a high‑capacity, complete water conditioner designed for both freshwater and marine aquariums. Tap water often contains chlorine, chloramines and heavy metals that can stress or damage fish, shrimp and beneficial bacteria.

Beyond basic dechlorination, DYMAX Instant Start 500ml is formulated with an additional disease‑preventative feature that promotes a healthy slime coat, giving your fish extra protection and helping to boost their natural immunity—especially useful in larger systems or fishrooms.
