COMBO DEAL – Voss Dosing Bottle Cap with 1/4″ Bulkhead & Acrylic Tube and Wall Mount


SKU: N/A Categories: , , Tags: , , , ,


The sparkling water brand VOSS has become a very popular container within the reefing community to use for dosing. Many reefers punch a whole in the top and scrape off the lettering for a more finished look.

We’ve designed a cap & wall mount combo with lots of color options to match your tank scheme and to make a dosing solution a turn key solution. You just have to supply the Voss container. The container is not included in the purchase.

1/4″ Bulkhead & inside Acrylic tube are included.

Wall Mount Dimensions (Length x Depth from Wall X Height)
Glass 375mL = 3.8″ x 3.1″ x 1.8″
Plastic 500mL = 3.8″ x 3.2″ x 1.8″
Glass 800mL = 4.2″ x 3.4″ x 1.8″

These Voss bottles are known to work with our caps
– Plastic 500ml bottle sold at many gas stations for a couple bucks
– Glass 800 ml bottle sold at more upscale grocery stores.
– Glass 375mL (flavored) bottles sold at many CVS’s, etc.

You’ll need 1/4″ R/O Tubing to work with the bulk head. You can order it here from amazon. You can also find other colors on Amazon or a local hardware store.

IMPORTANT NOTE: You will needs a more ridged 1/4th tube going into the top, to form a good seal for a dosing pump within the bulk head. Using flexible tubing will most likely not hold a tight enough seal.
