What do Red Sea conditioners do in a reef aquarium?

Red Sea conditioners neutralize harmful substances like chlorine, chloramine, and heavy metals. Some formulas also detoxify ammonia and support fish immune systems, making them ideal during water changes or after introducing new livestock.

When should I use a water conditioner in a marine tank?

Use a conditioner during water changes, after transporting or acclimating fish, or if your tap water contains chlorine or chloramine. They can also help stabilize ammonia spikes in emergency situations.

Can I use Red Sea conditioners with other Red Sea products?

Absolutely. Red Sea conditioners are formulated to integrate with other Red Sea systems, including salt mixes, test kits, dosing programs, and reef supplements. This ensures stable chemistry and easy system compatibility.
