COLLECTING WATER AND NO PROTEIN
1. Lower the variable discharge tube in ½”increments until the bubbles stop
overflowing into the collection cup and the unit begins to skim. Loosen the
discharge compression nut and lower variable discharge tube.
Tighten discharge compression nut to set.
2. If the variable discharge tube is as low as possible and water is still collecting
in the cup, then start to increase the volume of air by turning the air control
valve towards the H by a 1⁄8of a turn until the unit begins to skim. By increasing
the air volume it will decrease the water level and speed of the water entering
and exiting the skimmer.
Note:
• Set salinity at 10.0022-10.0025.
• The use of certain water conditioners will cause excess bubbles and
the skimmer to collect excessive water. This will occur until the water
conditioner is completely removed. Certain water conditioners that
increase slime coat are more prone to affect to the skimmer.
• The use of medications will cause excess bubbles and the skimmer
to collect excessive water. This will occur until the medication in the
water is completely removed.
• if the water level in the sump is too high that above 5.5”-9.5”, It will
cause the skimmer to collect excessive water.
NOT SKIMMING AND NOT COLLECTING ANY PROTEIN
1. Decrease air volume by turning the air control valve towards the L by a 1⁄8of a
turn until the unit begins to skim.
2. Raise the variable discharge tube in ½”increments until the bubbles reach
halfway up the neck of the collection cup. Loosen the discharge compression
nut and raise the variable discharge tube. Tighten discharge compression nut
to set. Wait a short period of time and if skimming does not begin, raise the
variable discharge tube a small amount (approximately 1⁄8”). Continue to raise
the variable discharge tube until the unit begins to skim.
Note:
• Set the salinity at 10.0022-10.0025.
• There must be a biological load. In short there must be livestock in
the aquarium.
• The collection cup has not been washed with a mild detergent.
• Water level in the sump is too low, around 5.5”-9.5”.
