What to Compare Before Buying

  • Aquarium type: This conditioner is stated for freshwater and marine aquariums. Check that this matches your setup.
  • Treatment size: The bottle contains 5 litres, so compare it with how much conditioner you want to keep on hand.
  • Water-change routine: The product is intended for use when preparing tap water for aquarium use, so consider whether that suits your maintenance routine.
  • Marine aquarium use: If using it in a marine aquarium, the protein skimmer should be switched off to avoid excess foam.

What Else You May Need

For marine aquarium use, a protein skimmer needs to be switched off during use to avoid foam formation. Make sure your aquarium care routine allows for that step.

Before You Decide

Check that the 5 litre size suits the amount of water you condition, and confirm that the product fits your aquarium type. If you keep a marine tank, remember the protein skimmer note before choosing an offer.
