Here’s a detailed guide to the WEEK AQUA CO₂ Regulator, a dual-gauge regulator with solenoid, tailored for planted aquariums:

🌟 WEEK AQUA CO₂ Regulator with Solenoid — Overview

The WEEK AQUA Dual‑Gauge CO₂ Regulator with Solenoid is designed for reliable, automated CO₂ injection in aquatic plant tanks. Featuring precision controls, corrosion-resistant construction, and global compatibility, it offers professional-grade performance at a competitive price point (Aqua Zones).

🔧 Key Features & Build

• Dual Gauges: Monitor cylinder pressure and working/output pressure (≈ 43–87 psi inlet, up to ~2175 psi tank pressure) (Aqua Zones).

• Fine‑tuning Needle Valve: Internal copper valve needle for precise bubble adjustment (e.g. 1 bubble per 2–3 sec) (Aqua Zones).

• Durable Body: Machined from anodized aluminium alloy with CNC-integrated molding—lightweight and corrosion-resistant (Aqua Zones).

• High‑quality Seals & Threads: “MPu Material” seals and thick wear-resistant threading ensure leak‑free connections (Aqua Zones).

• Solenoid Valve: Cools during operation (“cool touch”), powered AC100–240V, output DC24V—suitable for timers or controllers (Aqua Zones).

• Compatibility: Accepts both G5/8 and W21.8 threading (common in India and globally) (Aqua Zones).

✅ Benefits

• Stable CO₂ Delivery: Needle valve allows fine control, reducing fluctuation in bubble rate.

• Automated Timing: The solenoid supports timed control—ideal for daytime CO₂ dosing.

• Visual Clarity: Dual gauges and bubble flow window give real-time feedback.

• Built to Last: Robust aluminium build, anodized finish, and strong seals.

• Versatile Configuration: Works with most domestic and imported cylinder fittings.

🚀 Setup & Operation Tips

1. Attach regulator to CO₂ tank (ensure seal and thread compatibility).

2. Connect tubing from outlet to bubble counter, check valve, and diffuser.

3. Plug solenoid into a timer to switch CO₂ during photoperiod.

4. Adjust needle valve gently—small turns cause large bubble-rate shifts.

5. Monitor pressure gauges to track cylinder remaining pressure (~700‑800 psi ideal) (Planted Tank, Reddit, weekaqua.lk, Aqua Zones, YouTube, UK Aquatic Plant Society, Reddit).

⚠️ Drawbacks & Considerations

• Limited User Feedback: Few user reviews are available; two reviews gave high ratings, though sample size is small (Planted Tank).

• Unknown Long-Term Reliability: No widespread hobbyist consensus yet; limited information compared to brands like CO₂Art or GLA.

• Aluminium vs Brass: Aluminium regulator bodies are lighter but may be less corrosion-resistant over long periods than brass options.

🔄 Comparisons with Other Brands

• CO₂Art, GLA, FZONE: More widely reviewed and trusted alternatives.

• Users often prefer CO₂Art or GLA for superior needle-valve precision and long-term reliability, despite higher cost (Reddit, Aqua Zones).

• FZONE regulators are value-oriented and sometimes criticized for inconsistent quality, whereas WEEK AQUA aims for greener engineering and build. Still, it's newer in the market (weekaqua.com).

🧼 Maintenance Tips

• Inspect seals periodically for wear.

• Clean with water and dry thoroughly after use.

• Lubricate the needle valve lightly if stiffness develops.

• Ensure patience when adjusting—small movements make big changes.

🛠️ Quick Tech Specs

📝 Summary

The WEEK AQUA Dual Gauge CO₂ Regulator with Solenoid offers advanced features—dual gauges, precise valve, solenoid automation, and solid construction—for a reasonable investment. It's ideal if you're on a mid‑budget and need both Indian and foreign thread support. However, it lacks broad user reviews and long-term feedback compared to industry leaders like CO₂Art or GLA.
