Made of high-quality brushed aluminum Holds 5 pounds of CO2 Can be filled easily at any USA or Canada fill station The SR Aquaristik 5 LBS Aluminum CO2 bottle is a key component to any aquarium CO2 system. The aluminum bottle is much lighter and more attractive than the steel bottle and will not rust or cause discoloration from sitting inside aquarium cabinets. This bottle comes standard with a CGA 320 valve and is compatible with most North American CO2 regulators. Specifications: Tare weight 7.7 pounds CGA 320 valve Working pressure 800 psi All tanks are shipped empty.  Unfortunately we are not able to ship any CO2 bottles full. If you are a local customer, we are happy to refill or swap CO2 bottles.

Accurate and Reliable Simple and Easy Installation Perfect for use in CO2 Setups and Calcium Reactors ACCURATE. SIMPLE. RELIABLE. 24/7 PH CONTROL. The Milwaukee MC122 PRO pH controller lets you measure and adjust pH levels automatically. WHAT PEOPLE ARE SAYING "I run this unit 24/7 and have not had any problems for the past two months. It keeps my fish tank CO2 injector running perfectly and puts my mind at ease regarding overdosing." "I've been using this controller for two years to monitor and adjust pH of hydroponic nutrient solutions. Still using the original probe and it rarely needs calibration." "Using this as a pH controller for a calcium reactor on a 105 gallon reef tank ... I recommend this to any serious reefer." SUMMARY The MC122 controller automatically monitors and fine-tunes the pH levels. Just set your pH parameters and let the Milwaukee pH Controller do the rest. The Milwaukee PRO pH controller is preferred by people looking to dial in their testing program when they have an ongoing need to maintain levels. Common uses are nutrient tanks and aquariums. The Milwaukee PRO pH controller offers: ACCURACY The Milwaukee PRO pH controller offers an accuracy to ± 0.2 pH with two point manual calibration. AUTOMATION The controller provides a control range of 5.5 to 9.5 pH with alarms that activate when readings are higher or lower than set point. COMPATIBLE DOSING PUMP Milwaukee offers the MP810 dosing pump EASY INSTALLATION The pH Controller comes with a complete mounting kit including a probe holder. DESIGN FEATURES Fast easy to read current results with large digital LCD readout Accurate to ±0.2 pH (0.0 pH to 14.0 pH) with the user selectable high/low set points Simple two-point calibration for increased accuracy with manual trimmers for easy adjustment Gel-filled, double junction lab grade pH electrode for low maintenance and high performance 6.5 feet probe cables for extra flexibility when testing 12 VDC power supply USE AND CARE  pH meters usually start performing poorly because of problems with the probe. The two parts of the pH probe that cause problems are the glass sensing bulb and the reference junction. SENSING BULB The glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes. REFERENCE JUNCTION The reference junction is a small hole that allows the meter to compare the sample to a reference. The reading is generated based on the electrical difference between the sample and reference. If the junction hole gets clogged, the pH probe will no longer function. You can extend the life of your pH electrode in the following ways. STORAGE The pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged. Storing in a pH probe storage solution or pH calibration buffers will help address both these issues. Do not store it in tap water and DI water. This will damage the sensitivity of the probe. The best way to store the probe is with the probe's cap filled with a storage solution for calibration buffer and the cap tightened to prevent leakage. It is also recommended to store the electrode upright to further reduce the potential for leakage. CLEANING Residue from the sample can impact the sensitivity of the sensing bulb and clog the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking your electrode in a cleaning solution. CALIBRATION The pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your PRO pH controller accurate. Also, calibrate after cleaning or a long period of storage.
