Bullets 1, 2, and 3

Can I install the Bullet Series in my reservoir? Yes, as long as the drain of the skimmer is not completely covered in water. The drain is centered 3” off the bottom. Exception to this rule is the Bullet-1 which can be in 6” of water. Most users will raise the skimmer up using one of the Precision Marine Stands. Can I install the Bullet Series out of my reservoir? Yes, as long as drain of the skimmer is returned above the running water level in the reservoir. Most users will install a bulkhead fitting in the reservoir and plumb the skimmer directly to it. You can even attach the gate valve to the bulkhead for a professional installation. Can I reduce the size of the drain plumbing? Never reduce the size of the drain. Water will not be able to exit the skimmer fast enough, and your water level will be too high. Is there supposed to be water in my Bullet Injector? Yes, the injector body will have nearly 1.5” of water in it when the pump/skimmer is running. This is equal to the height of the four air intakes. How high is the water level supposed to be in the first clear tube (riser)? We recommend maintaining the water level no more than 1” into the riser tube. When the water level is above 1”, the water becomes turbulent and the foam is less stable. You can wet skim by adding more air. Is there such a thing as too much air? Yes, there is. If you open your air valve more than necessary, the bubble size will be compromised (too big) and your skimmate will be very wet. The more pressure you build before the bullet injector, the finer your bubble size. Can I use too big of a water pump? Yes, but it would have to be very large. Please follow the guidelines in the table of the your instruction manual for pump size. Choose the largest pump with the table for your model for best results. How often do I need to clean the injector? This depends upon your mechanical filtration before the water hits the injector. If large debris is drawn into the pump feeding your skimmer, the debris may get trapped in the injector passages, decreasing its performance. Additives such as calcium hydroxide can build up in the passages in the injector. In either case, cleaning the injector is fast and easy with the Precision Marine Quik-Lok Injector. Routine cleaning should be performed every three months or whenever you notice diminished air quality. Is the Bullet Series compatible with Ozone? Most definately. Use the black barbed fitting supplied with your injector. How do I clean the muffler? Depending upon how dirty the muffler is, you can use simply use freshwater or soak in a diluted bleach solution overnight. If you use bleach, be sure to rinse the muffler well until you no longer smell the bleach.

Bullet XL Series
		Can I install the Bullet XL Series both inside or outside of my reservoir? Yes, as long as drain of the skimmer is returned above the running water level in the reservoir. When plumbing the skimmer drain back to the reservoir, do not run the drain vertically more than 1/2 the height of the reaction chamber (ex: 9” for the XL1, 12” for the XL2, 18” for the XL3 and 24” for the XL4). Can I reduce the size of the drain plumbing? Never reduce the size of the drain. Water will not be able to exit the skimmer fast enough, and your water level will be too high. Is there supposed to be water in my Bullet Injector? Yes, the injector body will have nearly 1.5” of water in it when the pump/skimmer is running. This is equal to the height of the four air intakes. How high is the water level supposed to be in the main reaction chamber? We recommend starting with the water level 1” below the threaded flange (where the cup attaches). After break-in , raise the water level to achieve the desired foam Is there such a thing as too much air? Yes, there is. If you open your air valve more than necessary, the bubble size will be compromised (too big) and your skimmate will be very wet.

ES100
		Can I install the ES100 both inside or outside of my reservoir? Yes, as long as drain of the skimmer is returned above the running water level in the reservoir. When plumbing the skimmer drain back to the reservoir, do not run the drain vertically more than 1/2 the height of the reaction chamber (equal to 7 inches). Can I reduce the size of the drain plumbing? Never reduce the size of the drain. Water will not be able to exit the skimmer fast enough, and your water level will be too high. How high is the water level supposed to be in the main reaction chamber? We recommend starting with the water level 1” below the threaded flange (where the cup attaches). After break-in , raise the water level to achieve the desired foam Is there such a thing as too much air? No there isn’t. The larger the water pump the more air and the smaller the bubble size. Can I use too big of a water pump? Yes, but it would have to be very large. Please follow the guidelines in the table of the instruction manual for pump size. Choose the largest pump in the table for the best results. How often do I need to clean the venturi? This depends upon your mechanical filtration before the water hits the venturi. If large debris is drawn into the pump feeding your skimmer, the debris may get trapped in the venturi, decreasing its performance. Routine cleaning should be performed every three months or whenever you notice diminished air quality. How do I clean the venturi? While the skimmer/pump is running, simply allow HOT water to be drawn into the airline attached to the venturi. Salt deposits atomize inside the venturi and the hot water will dissolve them quickly. Is the ES100 compatible with Ozone? Most definately. Simply attach the ozonizer to the venturi airline and the venturi will draw air through the ozonizer. There is no need for an air pump. Be sure to place the ozonizer ABOVE the protein skimmer so water does not flood the ozonizer when power fails..

HOT-1

Can I place the HOT-1 in the reservoir? No, it’s best to hang the skimmer directly on the tank. The head pressure from pumping above the reservoirs water level greatly diminishes the amount of air the pump can draw. We believe the performance is unacceptable. How do assemble the water pump and attach it to the to the skimmer? Pictured is the Maxi-Jet 1200 with venturi kit assembled and attached to the skimmer input tube. When will the bubbles stop coming from the drain of my skimmer? Once the protein skimmer has “broken in”, air will cease to leave the drain. Typical break-in periods are 24-48hrs. Skimmers set up on newly established tanks without organic loads will allow more air to escape due the lack of surface tension. When an organic load is present, the air mass inside the skimmer will “tighten up” and the air will stop escaping the drain.

Waste Collectors

What is a Waste Collector and how does it work? A Precision marine waste collector is a vessel designed to hold the skimmate that flows from the fixed drain in the skimmer cup. It is designed to stop the flow of skimmate or water should it fill entirely. This is helpful if your protein skimmer should over-foam due to a mis-adjustment or additives used in the aquarium. In addition, there is a space built-in for the use of activated carbon to remove odors or residual ozone if you choose. Do I need a Waste Collector? No, you do not need to use one, however, you will need to use some form of collection for skimmate as all Precision Marine Protein Skimmers employ a fixed drain (excepting the HOT1 standard).
