Repashy Soilent Green Algae Gel Food

Repashy Soilent Green is an algae and plankton based meal-replacement gel for the grazers in your tank. Built around spirulina, chlorella, and kelp with a plankton boost, it recreates the green "aufwuchs" film that herbivorous and omnivorous fish and invertebrates naturally rasp off rocks, in both freshwater and saltwater systems. Mix the powder with hot water, let it set, and feed. Explore the rest of our aquarium foods while you stock up.

Why Repashy Soilent Green

• Green algae base of spirulina, chlorella, and kelp for the plant matter grazers need, plus plankton for omnivores.
• Mimics natural aufwuchs, the algae and microorganism film that mbuna, tangs, and plecos graze in the wild.
• Freshwater and saltwater, equally at home feeding African cichlids and plecos or marine tangs and angelfish.
• Gel feeding keeps water cleaner, it holds together while fish graze instead of dispersing like flake.
• Mix only what you need, the dry premix is shelf-stable, so you prepare fresh gel on demand. Made in the USA by Repashy Superfoods.

How to Prepare

Mix 1 part powder with 2 to 3 parts boiling water, stir until smooth, and pour into a container or mold. The gel firms up at room temperature in a few minutes. Once set, cut it into portions and feed. Treat prepared gel as fresh food: keep it sealed in the refrigerator for up to two weeks, or freeze for up to six months.

Who It Is For

Algae and plankton eaters across both worlds: African cichlids, plecos, and silver dollars in freshwater, tangs and marine angelfish in reef and fish-only tanks, plus grazing shrimp and snails.

FAQ

Is it for freshwater or saltwater?
Both. Soilent Green is a go-to for freshwater grazers like mbuna and plecos and for marine herbivores like tangs and angelfish.

How do I make it?
Stir 1 part powder into 2 to 3 parts boiling water, then let it set into a firm gel at room temperature. Cut into portions and feed.

How do I store it?
The dry powder is shelf-stable. Once made, keep the gel sealed in the fridge for up to two weeks or freeze for up to six months.

Will it cloud my water?
No. Because it sets into a firm gel, it holds together while your fish graze instead of clouding the water like flake or powder.
