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. DYMAX Instant Start 500ml neutralises these contaminants at typical tap water levels so you can safely use new water in your aquarium straight away.
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.
