Red Sea Reef Energy Plus Coral Food, 500 ml, AB+, all in one, for saltwater aquariums

One 500 ml bottle holds this all-in-one liquid coral food. It suits saltwater aquariums that keep Soft, LPS, SPS and non-photosynthetic corals, and the bottle works with an automatic doser. The Classic style carries model number R22103, and the bottle weighs 550 g (1.21 lb).

What goes into the all-in-one liquid

The mix delivers an organic complex in dissolved and suspended form. Its simple building blocks are vitamins, fatty acids, amino acids and carbohydrates, all supplied together. Red Sea states that corals take up and use each component in their metabolic processes, and that this leaves the aquarium without unnecessary polluting organic material.

Because everything is blended into one liquid, the bottle replaces a separate product for each group named on it: Soft, LPS, SPS and non-photosynthetic corals.

One bottle, one pump line, one week out of the fridge

An all-in-one formulation means a single liquid is what you dose, so the doser draws from one container rather than from several. The maker says a bottle can sit on a dosing line for as long as one week, since the mix may remain unstirred and unrefrigerated for that period.

When you refill the dosing container, the stated care step is to wash it with soapy water first. Red Sea also gives a lighting note: under LED lighting, increase the dose if the corals are not growing, even when there are no signs of photoinhibition.

Does this suit your tank and doser?

Check the coral groups in your tank against the four the manufacturer names: Soft, LPS, SPS and non-photosynthetic corals. The bottle is made for saltwater aquariums, and the stated use is feeding corals.

If you dose automatically, the 500 ml bottle is listed as suitable for use with automatic dosers. Keep any unrefrigerated portion within one week, and refrigerate what sits longer than that; leaving Reef Energy Plus unrefrigerated for more than a week goes against the manufacturer's care instructions.
