Reef-Reactive Sump Kit for 20 Gallon Long Aquarium

From: $124.95

(2 customer reviews)

Our Deluxe Sump Baffles Kit for 20 Gallon Long Aquarium is designed to convert a standard 20G long (Petco) glass aquarium into a fully functional sump. A 20G sump can support up to a 75 gallon reef aquarium for nutrient export and filtration. Included two fluorescent glow media trays for added aesthetic.

One of the biggest advantage to retrofitting (DIY) your own sump is the flexibility of the compartment spacing. Since you'll be siliconed in the baffles yourself, the width of the compartment (skimmer/refugium/return) can be spaced to your personal preference.

We recommend GE Silicone for Plastic that will bond well to both acrylic and glass vs regular glass silicone, and it is completely reef safe. Please pay attention to the “expiration date” near the bottom of the tube when purchasing, an expired tube can be frustrated to work with and won’t fully cure.

*Aquarium, skimmer, and silicone not included.

  1. Couldn’t be happier. I now have a 20 gallon sump that looks and functions like a $300 sump for a third of the price. And that orange
    Is amazing.
