Description: CO2 Regulator with dual gauges and independent Needle Valve for regular CO2 cylinders, Red Sea. Designed specifically for aquarium use, the Pressure Regulator and Needle Valve are independent units connected by low-pressure CO2 tubing. The high precision fine-flow needle valve is designed to be mounted on the side of the aquarium enabling easy access for regular flow adjustment or complete shut off. Once assembled and set to the desired working pressure the CO2 Cylinder/Regulator can be located out of site, behind the aquarium. Independent needle valve allows for stable flow rates of CO2 as low as 4 bubbles per minute

Description: Red Sea CO2 Solenoid valve. Too much CO2 can reduce the pH in an aquarium to levels that are stressful for fish. For the safe use of CO2 it is highly recommended to automate the CO2 system with either a simple time switch or by a pH controller. The in-line solenoid valve connects the CO2 system with either of these devices. Includes tubing and a standard 1/8-inch compression fittings. Uses 2-watts.

Description: 20 oz. CO2 Cylinder with Pin Valve. This is a paintball style CO2 cylinder.

Kalkwasser Reactor. The Kalkwasser Reactor is a sealed unit designed to supply reef aquaria with calcium by enriching the fresh water top up supply. It uses the Kalkwasser-method and is filled with calcium hydroxide, which is agitated by a pump. It is possible to automate the system by combining an automatic level controller such as the ab aquaniveau single with the Aqua Medic Kalkwasser Reactor. The reactor is engineered to take a pH electrode to control the quality of the kalkwasser. An additional advantage of this method is, that phosphate is removed from the top up and the aquarium water. 1 per case.

KALKSTAR Kalkwasser stirrer. Magnetic stir bar design with digital control panel. OPERATION: The KalkStar has a control panel with a digital display, four mode indicator LED?s and four soft-touch menu buttons. Three operational parameters that are fully controllable from the soft-touch menu buttons are speed (revolutions per minute), interval (hours) and duration (minutes). Speed is the speed at which the magnetic stir bar is rotating in the reaction chamber. The speed setting can be adjusted from 100 to 2000 rpm. Interval is the time period in hours that the KalkStar pauses between cycles. The interval can be set from 1 to 24 hours. A 0 hour setting for the interval can also be selected which will allow the KalkStar to complete the current program or duration and then return to the PAUSE mode without restarting the program. The duration is the time in minutes that the KalkStar will operate before pausing for the selected interval time. The duration can be adjusted from 1 to 60 minutes. In overview, the Kalkstar can be programmed to operate for a duration between 1 and 60 minutes. The KalkStar will pause for the selected interval time period and restart the program for the selected duration again and again until the unit is paused or the unit is reprogrammed. In the event of power outage, the default program will be restored. The default program is 1600 rpm with a 15 minute operational duration and a 4 hour interval. Digital Display: The current selected parameter is displayed on the screen. As the menu buttons are pressed to toggle through the different parameters, they will be displayed on the screen. Mode Indicator LED?s: Located adjacent to the display screen, the LED?s will indicate which parameter is currently being displayed on the screen. The three parameters are speed (rpm), interval (hours) and duration (minutes). A pause LED will indicate if the unit is in PAUSE mode. Due to the size of the display screen the speed (rpm) is displayed divided by 100, i.e. if the display indicates 12 for speed, the actual KalkStar rpm is 1200. Soft Touch Menu Buttons: Control of the KalkStar is accomplished with four menu buttons located to the right of the LED indicators. From left to right, the STOP button (small square in the center) will toggle through the different operation parameters (speed, duration and interval) while in PROGRAMMING mode. The UP and DOWN menu buttons toggle the display value and LED indicator between the speed, duration, and interval parameters. The UP and DOWN menu buttons will also increase or decrease the three operational parameters (speed, duration and interval) while in PROGRAMMING mode. The PAUSE button will pause the operation of the KalkStar unit. The PAUSE button will also exit PROGRAMMING mode and return the KalkStar to normal operation if in PROGRAMMING mode.

A.R.M. Calcium Reactor Media, 8 lbs. A complete reactor media containing not only calcium and carbonate, but essential trace elements as well. In fact A.R.M. has nearly 50 times the strontium of other brands (7390 ppm). A.R.M. is processed for immediate use, no rinsing required, and has double the surface area of regular aragonite. Precision grading (2-3 mm) allows for maximum carbon dioxide penetration, and the exclusion of gastropod shells insures the lowest phosphate (less than 1/10 of 1 ppm) and silica (about 1/2 that of other brands) content. This grading also carries in the highest concentration of Halimeda incrassata, an aragonite so pure it has been used as a laboratory standard. A.R.M. has the highest solubility of any reactor media available (metastable at 8.2) so CO2 consumption is much lower.

Jetstream-Pico the calciumreactor with gaswater separator and injector, complete with pump MJ 1000 and bubble counter. For 1 Iiter coralsand, for aquaria up to 500-600 liters (without fillings). (LxBxH) 130x155x400mm. The Jetstream calciumreactors were designed totally new and reach dimensions of efficiency second to none. Many users, if professionals or hobbyists know that they can dissolve coralsand in much higher quantities than in any other reactors before if these have static or moved fillings. If necessary it is possible to dissolve one filling per month. Carbondioxide is taken up by an injector system. Bubbles of carbondioxide which have not been used are recatched by a gas/water separator and are injected into the reaction chamber again. In this way not a single bubble can leave the reactor without having been used. Up to now, the rest gases, mostly nitrogen, has caused problems in every closed reactor, thus complicated and delicate degasing procedures have been necessary. The Jetstream reactors are the first which make use of this gas in a profitable way: It has a beneficial effect on the water flowing through the coralsand thus hinder the system in accumulation of fine slick. The whole filling is evenly dissolved. As a result the speed of current in the system is enhanced remarkably without diminsihing the solubility for carbondioxide. The outlet water is free of gas. Everyone can compare and test the capacities, the results are reproducable - Jetstream reactors are the first ones with performance diagrams!

Part Number: CR-VAACRO-AC-10 Brand Name: ViaAqua Description: Via Aqua ACRO Calcium Reactor AC-10. Acro-Cal Calcium Reactor. 14 ? inch H x 3 7/8 inch W Built in water pump. For use in sump or hanging. Comes with bubble counter. Easy to remove twist off top. Affordable. For aquariums from 10-75 gallons. Built in bleed valve. Acro-cal calcium reactor offers a simple and convenient solution for maintaining calcium and alkalinity in your reef tank. After the initial setup, the calcium reactor requires minimal maintenance. A calcium reactor is almost a necessity for tanks heavily stocked with stony coral where calcium and alkalinity demands are high and will promote coral line algae growth. Calcium reactors provide a steady supply of calcium by using CO2 to dissolve media in the reactor and, thus, releasing calcium into your water. The effluent released also acts as a buffer to stabilize kh.
