Before calling CPR's Technical Support, please take some time to look over this trouble-
shooting guide. Most of the problems associated with the performance of the
SR3 are due to improper maintenance of the venturi powerhead.
Trouble Shooting
Cause and Solution:
The surface tension of the water has been increased by the addition of additives,
medications, or conditioners. Disable the protein skimmer by submerging the airline
into the water (remove muffler first) for 24 hours while these additives are active in the
tank. Many products contain chemicals which will still be present in the aquarium after
24 hours. Running the protein skimmer as well as the use of activated carbon will help
to remove compounds which may be affecting surface tension.
The salinity may be too high.
The aquarium has just been cleaned or water has been changed. Synthetic salt mixes
often contain conditioners which increase the surface tension of the water. Bubbles
should disappear within 24 hours. Also check the silicate levels of your water.
The venturi air line is clogged with detritus or salt creep. This may increase the water
flow rate and possibly sweep the bubbles from the skimmer chamber back into the tank
before they can dissipate. The airlines should be cleaned regularly.
The rejuvenation plate is not set properly or is missing the small "O" ring that fits
around the plate. Remove the plate and make sure no detritus or calcium buildup is
preventing proper installation of the plate and that the "O" ring is intact. Be sure not to
break or bend the two clips which hold the plate in place.
The collection cup is not low enough. See instructions for the correct height of the
collection cup.
The biological load may not be sufficient enough to generate significant waste. A new
tank or a tank with supplemental filtration may produce limited waste and skimmate.
Skimmer chamber is not filled with micro bubbles. See next issue.
An airline or muffler may be blocked. Detritus, calcium and salt will build up in these
parts over time. Clean these parts regularly. Check the airline and pump for normal op-
eration. Also ensure airline is not submerged. If necessary, remove the pump from unit
for further testing.
The powerhead may need to be cleaned. If the powerhead becomes clogged with
organic or calcified material, the flow rate and the air intake rates may decrease. Follow
the instructions included with your powerhead for regular cleaning. Soaking the pump
in a diluted vinegar bath may also help break down calcified material.
Your tank may not have completed the nitrogen cycle.
Cleaning the powerhead at least once a month will ensure
optimal performance of the SR3.
