AQUATEK ChillMaster Cooling Fan Series

Q: Why can’t I fit the clamp bracket of ChillMaster cooling fan over the lip/edge of my tank?

A: The clamp bracket is designed to fit over aquarium lip 1/2 inch or less. These cooling fans are designed primarily to fit over salt water aquariums made with fortified glass, which are typically rimless (no lip).

But we can offer a quick fix for this problem. We suggest that you go to a nearby hardware store (Home Depot, Ace… etc) and purchase a piece of clear plastic (or pixie glass, they usually come in pre-cut 8×11 pieces) and a tube of epoxy (a special plastic adhesive). Once you have these items ready, thoroughly clean the outside edge of the aquarium where you would like to attach the fan to, then, glue the clear plastic piece to the outside of the edge. The plastic wall should rise at least 1 inch above the edge of your aquarium; this will ensure a secure fixture of the fan to the plastic wall.

Q: Can I change the direction of airflow when I am using ChillMaster cooling fans?

A: The direction of air flow can be easily changed by detaching the clamp bracket and swap the left to right and vice versa. The clamp bracket can be detached by removing the screw that is used to secure it to the frame of the fan.


AQUATEK CO2 Regulator Solenoid

Q: Why is brass body superior to aluminum for regulators?

A: Brass is the gold standard material to manufacture gas regulators.
Better Stability
Because brass has lower thermal expansion property (Brass: 18.7 10-6 m/m K; Aluminum: 22.2 10-6 m/m K) and better heat conductivity than aluminum, brass constructed regulator is capable of enduring temperature variation of the environment and achieve better stability and consistency during operation.

Corrosion Resistant
Brass is a highly corrosion resistant material in high humidity environment. Therefore, AQUATEK’s regulators are perfect for aquarium usage.

Less Leakage and Lasting Durability
Compared to aluminum, brass is a stronger and more durable material with higher density (very heavy) and is resistant to friction, wear and tear. It minimizes the connector’s thread from damaging which could lead to leakage. This is an important feature since we need to frequently assemble regulator onto the CO2 tank when the tank needs to get refilled.

Q: Why does not the output pressure meter drop to zero after detached from the CO2 cylinder?

A: If your CO2 cylinder is not equipped with pressure release valve, then, residual CO2 gas could be trapped inside the regulator causing the meter to register output pressure while detached from the CO2 cylinder. To reset the output pressure meter, simply loosen the needle valve and turn on the solenoid by plugging it into an outlet. The trapped CO2 gas will be released and meter will reset to zero.

Q: Where can I find the CO2 cylinders?

A: Contact local aquarium store, the local beverage factory which sells fountain drinks or local paintball shop.

Q: What is the proper maintenance for the solenoid?

A: Occasionally, there are dirt particles inside the CO2 tank, via the connector or the air tube that may get stuck inside the solenoid, which can affect its proper functioning (e.g. continue air leak after solenoid shuts off). To reverse this issue, simply cleanse the inner cavity of the solenoid by unscrewing the four screws and flush out dirt particles with an air canister. Post cleaning, enclose the solenoid by tightening the original screws. Before attaching the solenoid to your CO2 tank, you must first plug the regulator into a power outlet for 3 seconds and unplug. You should hear a “click” sound when the solenoid is plugged in. After this procedure, air leak issues should be mitigated.

AQUATEK 3-in-1 Diffuser with Bubble Counter and Check Valve

Q: What is the easier way to remove the ceramic disk to fill the diffuser with water?

A: Here is a tip to help you remove the ceramic disk for the first time: first, remove the plastic cap, then find the edge of the blue rubber ring and pinch on the edge to tug upwards. This may require a bit of force. You may also use a pair of tweezers to tug on the blue rubber ring. The first time is the toughest.
