Managing waste and ammonia is part of establishing and maintaining an aquarium, including tanks that contain fish or corals. One and Only Reef is made for new setups as well as routine care moments when tank conditions are being changed, such as filter cleaning or a water change. It is intended to create a biofilter without requiring a waiting period for that filtration to form.

What does One and Only Reef do in an aquarium?

DrTim's Aquatics One and Only Reef quickly converts waste into a non-toxic form and instantly creates a biofilter. That filter helps remove toxic ammonia and nitrite naturally. Aquarium waste can otherwise take up to 30 days to be eliminated, even with regular water changes and maintenance; the product is designed to address new tank syndrome.

• Designed for reef, nano and seahorse fish tanks.
• Made to support an environment for fish and corals.

When can I use One and Only Reef?

DrTim's Aquatics One and Only Reef can be used when starting a new fish tank, cleaning its filter, adding new fish or after a water change. These uses make it relevant both during aquarium setup and during ongoing maintenance. The product is presented as ready to use without waiting for the biofilter to develop.

• Suitable for use around filter cleaning.
• Intended for use when adding fish to the aquarium.

For these tank types, it combines waste conversion with a biofilter designed to remove ammonia and nitrite.
