CU-300 PROTEIN SKIMMER FOR STAND ALONE INSTALLATION                    (only 1 day skimming)

       

What is a PROTEIN SKIMMER and its function?

  • A protein skimmer is a mechanical device that removes dissolved organic compounds and particles from the water by separating foam which is created by the mixing of air and salt water.
  • The dissolved organic compounds and particles make up the ammonia, nitrite, nitrate, color, turbidity, odor, B.O.D, phosphate, taste, etc in the aquarium water.  Protein skimming will remove the following pollutants from the water that are not normally removed by other forms of filtration: food particles, feces, dissolved organic material, free floating algae, silica, amino acids, phosphate, hydrocarbons, ammonia, nitrite, nitrate, carbonates bicarbonates, dyes, enzymes, detergents, iodine, some of metal ions, protozoa, and bacteria.
  • It lowers pollutant concentrations before they break down into ammonia.
  • Be aware, protein foam skimming also removes valuable trace elements and nutrients.
  • However, protein foam skimming is one of the most important and useful methods to maintain a healthy environment for fish, invertebrates and coral.
  • The skimmer should be switched off for several hours after you do any of the following to your tank:
    1. Add trace elements.
    2. Add medication.
    3. Feed any suspended invertebrate food.

OPERATION

  1. Select the place where skimmer is put; In-sump or hang-on to the tank.
  2. Put the skimmer to the place your choose
  3. Make sure the skimmer is securely installed before operating it.
  4. Plug in power cord of pump into the grounded receptacle.  If power cord had been damaged or malfunctioned, discard the pump.  Do not attempt to repair pump
  5. After initial operation, check the water leakage from the skimmer body and tubing.  If you find out any water leakage, stop the operation of skimmer and repair it or return to the manufacturer
  6. If the condition of skimmer is perfect operate skimmer continuously.
  7. Adjust the water level in the column of skimmer up to water level line.  Water level can be controlled by adjusting outlet valve

SKIMMER INSTALLATION

For IN-SUMP installation

  • When sump space is available, install skimmer in a sump.  This is the simples and most efficient method
  • Connect the outlet valve, elbow, air tubing and inlet adapter as shown in the picture on the box
  • Connect one end of " flexible vinyl tubing to the inlet adapter of skimmer and the other end of the tubing to the outlet adapter of pump.  Use hose clamp (not included) to hold and secure the inlet adapter and outlet adapter to pump
  • Check the sump water lever.  The water level of sump must be lower than outlet of the elbow, which is placed in the horizontal position for proper drainage. 
  • If the sump water level is higher than 7", then the skimmer must be blocked up higher than the water level or the water level must be lowered so that the elbow is higher than the water level
For OUTSIDE-SUMP  installation -  When sump space is limited install the skimmer in this manner.  

 

  • IN-LINE installation: The outlet of skimmer connected with the sump tank's wall must be sealed tightly to prevent leakage (A hole must be cut in the sump tank wall)

  • Stand Alone installation: The outlet of skimmer must be higher than the wall of the sump.

WATER LEVEL ADJUSTMENT  & FORMATION OF FOAM

Water level adjustment Keep the water level shown by the sticker on top of the foot print (base) by adjusting outlet valve.  Do not raise water level above the line.  If the  water lever is raised above the line shown on the skimmer foot print, an overflow may happen and the formation of dry foam may be impeded
Formation of dry foam It will take time about 3 days at least or maybe more to produce dry foam.  This period my be reduced or extended according to the quality of your water or the load of marine life.  Do not increase or decrease the water level suddenly.  This will cause the making of efficient dry foam production to stop.  It is recommended that you use the pump with the proper capacity mentioned in the section of the skimmer specification for maximum efficiency

MAINTENANCE

For cleaning waste collection cup 1. Disconnect power cord before any cleaning
2. Grasp skimmer body with one hand and pull the waste collection cup straight up and out with the free hand.
3. Take out the waste collected in the collection cup and remove the debris by using a soft cloth or sponge to clean the cup under running water.
4. Replace the waste collection cup.
For cleaning the inside body of skimmer
  1. Disconnect power cord before any cleaning.
  2. Remove the waste collection cup.
  3. Remove the skimmer from the tank or sump.
  4. Take out water contained in the skimmer body.
  5. Clean the inside wall of skimmer body to remove debris or deposit by using a soft cloth or sponge with running water.
  6. Re-install the skimmer by reversing step.
  7. Make sure the skimmer is securely installed.
  8. If all are OK, operate skimmer.

TROUBLESHOOTING

Problem Potential Solutions
Pump is not running
  • Make sure that the power cord is plugged into the electrical outlet
  • Check pump for possible overheating or electrical shortage.  If pump is suspected of overheating or has an electrical short, discard the unit and use a new pump.
  • Unplug the power cord and check the impeller for blockage by foreign objects.  If blockage is present, clean impeller, shaft and impeller housing under running water.  Reassemble impeller unit and place into pump.  Re-plug the power cord and check for proper pump operation.
Water overflow into waste collection cup
  • Check the water outlet valve to ensure it is open.
  • Check the bubble elimination sponge for clogs.  If clogs are found, clean with running water and re-install for operation.
  • Check the pump capacity
  • Ensure water level does not exceed water level line label on the skimmer
New skimmer is not skimming waste It is normal for a new skimmer set up.  The proper dry foam that is needed to collect the protein in the salt water, will take approximately 12 to 34 hours to start skimming.  If you have a new tank set up or you have just changed water in your tank, it may take longer.
After installation of skimmer newly, protein skimmer seems not to work properly to make foam skimming
  • Do not worry about it.  It is normal. It will take time about 12 hours to make proper foam skimming after installation newly.
  • If there is not enough protein in the water, foam skimming will not  perform well.  This is normal.
