Shrimps Affair UGF set

Shrimps Affair UGF Set – Optimal pH Stability for Your Caridina Shrimp

The Shrimps Affair UGF set is a robust filter box made from high-quality, durable acrylic – perfect for shrimp aquariums with active soil. The box itself measures 15 × 15 × 9.5 cm (L × W × H). With the included adjustable riser tube, the total height becomes 23.5–35.0 cm – easily adaptable to your aquarium.

The four corners are reinforced with acrylic pieces that cover the glue joints internally. This prevents dirt and particles from penetrating the glued edges – ensuring cleaner operation and longer lifespan.

Why the UGF box from Shrimps Affair is perfect for shrimp

This smart solution (often called a soil filter or UGF for shrimp) is specially designed for shrimp aquariums with pH-lowering active soil (active buffering soil). By filling the box with a concentrated amount of soil, you get:

•  Fast and extremely stable pH reduction – the soil works effectively where the water circulates

•  Super easy soil replacement – just replace the soil in the box instead of disrupting the entire substrate

•  Longer durability of soil in the rest of the aquarium – the active effect is concentrated in the UGF box

•  Better control over parameters – ideal for sensitive Caridina species such as Crystal Red, Taiwan Bee, Blue Bolt, etc.

How to build your UGF box (from bottom up):

1.  Base plate placed at the bottom of the box

2.  Riser tube (with air hose and valve) placed on the base plate

3.  Coarse filter foam

4.  Ceramic filter media (ceramic rings / bio-media)

5.  Active soil (buffering soil) filled on top

Water is drawn down through the materials in the box and blown out into the aquarium via the riser tube – powerful biological filtration that keeps the water crystal clear and parameters stable.

What's included in the set?

•  Acrylic UGF box

•  Base plate

•  Adjustable riser tube

•  Air hose + air valve
→ Connect directly to your air pump (air pump not included)

How long does the soil in the box last?

Lifespan varies depending on water source (tap / RO), water change frequency, bio-load, and the type of soil you use. Since the amount of soil is less than with a full substrate, it needs to be changed more often – but that's precisely what makes the system so practical: quick and easy replacement without disturbing the shrimp or the rest of the aquarium.

Best tip: Measure pH regularly. When the value starts to creep up, it's time to change the soil in the box – this way, you keep pH low and stable with minimal effort.

Shrimps Affair UGF Set – the method many experienced Caridina breeders (including pros like Darick from Shrimps Affair) swear by for super stable parameters and healthy, colorful shrimp in shrimp aquariums.
