GloFish Aquarium Gravel, 5 Pounds

GloFish Aquarium Gravel is a colored gravel designed to glow under GloFish blue LED lights. This listing is the Pink/Green/Blue Fluorescent mix in a 5 pound bag. The same gravel comes in black with fluorescent accents, solid black and a pearlescent version, all in 5 lb bags.

How it glows

The fluorescent pieces absorb blue light and re-emit it as bright color. Under a white light they look like ordinary colored gravel; under blue or actinic light they stand out sharply. It is meant to work with GloFish fish, plants and ornaments, which are sold separately.

Picking a color

• Pink/Green/Blue mix: the most colorful option.
• Black with fluorescent accents: a dark base with glowing flecks.
• Solid black: lets the fish and ornaments be the only things that glow.
• Pearlescent: a lighter, shimmery look.

How much you need

For an even layer about 1 to 2 inches deep, a 5 gallon tank typically needs one or two bags, and a 10 gallon around two to three. Add more at the back if you want a slope.

Prep

Rinse the gravel in a bucket until the water runs clear before adding it. Colored gravel can carry fine dust from shipping.

Plants

Gravel this size is inert. Hardy plants like anubias and java fern can be tied to decor; rooted plants need root tabs. Many GloFish keepers use artificial plants to keep the glow theme.

Cleaning

Gravel traps waste between pieces, so vacuum it during each water change with a siphon such as the Python Pro-Clean. Clean gravel keeps colors vivid and water clear.

Lighting

To get the full effect, use a blue or color-capable light. A simple RGB bar like the hygger 26W 24/7 light lets you switch to blue for the evening.

GloFish are active swimmers, so leave open swimming space and keep tall decor toward the back. A tight-fitting lid stops the occasional jumper, and steady temperature keeps their colors at their best.
