API Tap Water Conditioner for Singapore Tap Water

This is a super-concentrated dechlorinator, and concentration genuinely matters in Singapore because our tap water carries chloramine, not just chlorine. Chloramine won’t dissipate by letting water stand, so it must be chemically neutralised before any water reaches your fish. A single ounce treats a large volume, which makes this an economical pick for keepers running multiple tanks or doing frequent water changes across a busy fish room.

Beyond removing chlorine and chloramine, it detoxifies heavy metals and works in both fresh and saltwater, so one bottle covers most setups in a typical HDB or condo. We always recommend conditioning before the fresh water goes in, especially for sensitive species and shrimp, since even a routine change of warm tap water can stress fish if it’s untreated. The concentrated dosing also means the bottle lasts a long time on the shelf.
