Ammonia (NH3-4)
Natural Seawater Value: 0.010 mg/L
Acceptable Range: 0.000 to 0.050 mg/L
Tested: 0.009 mg/L
(GOOD) Your ammonia level is within the recommended range. We
recommend staying with the current feeding and stocking levels. Be sure to
maintain a good schedule of water changes and additives. Ammonia levels
can rise after the addition of new animals, after a water change, or after the
changing of food diet. Any ammonia level above 0.05 mg/L is a cause for
concern, and the source should be found and corrected.
Nitrite (NO2)
Natural Seawater Value: 0.010 mg/L
Acceptable Range: 0.000 to 0.100 mg/L
Tested: 0.005 mg/L
(GOOD) Your nitrite level is within the recommended range. We recommend
continuing with your current maintenance and feeding schedules. Residual
levels of nitrite are common in marine aquariums. Levels of 0.05 or less are
of little concern. If the levels are higher than this, the source should be found
and corrected.
Nitrate (NO3)
Natural Seawater Value: 0.050 mg/L
Acceptable Range: 0.000 to 25 mg/L
Tested: 2.6 mg/L
(GOOD) Your nitrate level is within the recommended range. Be sure to
maintain reasonable stocking and feeding levels, as well as a regular water
change schedule. Nitrate is not toxic in and of itself, but a rising level is
indicative of deteriorating water conditions, and any level above 5.0 mg/L in
reef aquariums is a reason for concern.
Phosphate (PO4)
Natural Seawater Value: 0.030 mg/L
Acceptable Range: 0.000 to 0.250 mg/L
Tested: 0.23 mg/L
(GOOD) Your phosphate level is within the recommended range. We
recommend continuing the current maintenance and water change schedule.
The use of a phosphate absorbing resin is recommended to keep phosphate
levels below 0.05 mg/L.
Silica (Sio2-3)
Natural Seawater Value: 0.040 mg/L
Acceptable Range: 0.000 to 0.500 mg/L
Tested: 0.3 mg/L
(GOOD) Your silica level is within the recommended range. We recommend
regularly checking your make-up/top-off water for silicates. Continued use of
an iron-based, phosphate/silicate resin would be beneficial to maintaining this
level. High silicate levels can cause diatom blooms within the aquarium.
Potassium (K)
Natural Seawater Value: 390 mg/L
Acceptable Range: 350 to 450 mg/L
Tested: 331 mg/L
(LOW) Your potassium level is too low. We recommend performing a partial
water change, and possibly adding a commercial additive containing
potassium. Potassium is rapidly depleted from aquarium water by several
plant and animal metabolic processes. Maintenance of appropriate levels is
critical for cellular respiration, as well as being an important nutrient for coral
zooxanthellae and macro algae.
Calcium (Ca)
Natural Seawater Value: 400 mg/L
Acceptable Range: 350 to 450 mg/L
Tested: 358 mg/L
(GOOD) Your calcium level is within the recommended range. We
recommend that you continue with your current schedule of calcium
additions. Calcium is critical to healthy coral skeletal growth, and many other
biological processes. Maintenance of calcium levels that are at or near
seawater values is an important factor in having a healthy reef aquarium.
Boron (B)
Natural Seawater Value: 4.6 mg/L
Acceptable Range: 3.0 – 6.0 mg/L
Tested: 2.5 mg/L
(LOW) Your boron level is too low. We recommend performing a water
change, and possibly the addition of a commercial buffer containing borate
salts. Boron is an important part of the water buffering capacity, and a lack of
boron can lead to dangerous fluctuations in pH and alkalinity.
Molybdenum (Mo)
Natural Seawater Value: 0.01 mg/L
Acceptable Range: 0.0 to 0.12 mg/L
Tested: 0.3 mg/L
(HIGH) Your molybdenum level is too high. Molybdenum is found in many
common additives and at highly elevated levels in most salt mixes and so a
vast majority of reef tanks demonstrate a level 10 to 50 times higher than
natural levels. 0.12 mg/L is the upper toxicity limit for Molybdenum, the
point at which negative effects can begin to manifest themselves. You should
suspend the use of any additives containing molybdenum. If your level is
significantly higher than acceptable you may benefit from a partial water
change to reduce this level, though your salt mix may be a contributor to the
elevated level itself. Molybdenum is important for the biological processes of
bacteria, and may be of some benefit to corals as well. High levels of
molybdenum are known to encourage blooms of slime algae or cyanobacteria.
Strontium (Sr)
Natural Seawater Value: 8.1 mg/L
Acceptable Range: 5.0 to 12.0 mg/L
Tested: 8.7 mg/L
(GOOD) Your strontium level is within the recommended range. We
recommend continuing with your current additive schedules. Strontium is
important to coral growth, as they incorporate strontium ions into their
skeletal mass, particularly SPS corals. It is also important to coralline algae
growth.
Magnesium (Mg)
Natural Seawater Value: 1280 mg/L
Acceptable Range: 1100 to 1400 mg/L
Tested: 1163 mg/L
(GOOD) Your magnesium level is within the recommended range. We
recommend staying with your current water change and additive schedule.
Magnesium is a very important part of the water buffering system, and is
incorporated into coral skeletons. It is also critical to any photosynthetic
processes.
Iodine (I¯)
Natural Seawater Value: 0.060 mg/L
Acceptable Range: 0.030 to 0.090 mg/L
Tested: 0.04 mg/L
(GOOD) Your iodine level is within the recommended range. We would
recommend continuing with the current water change and additive schedule.
Please be advised that many iodine supplements are difficult to dose
accurately, and “above normal” readings are easy to achieve with common
iodine additives.
Copper (Cu++)
Natural Seawater Value: 0.030 mg/L
Acceptable Range: 0.000 to 0.030 mg/L
Tested: 0.02 mg/L
(GOOD) Your copper level is within the recommended range. We recommend
continuing with your current water change schedule, being careful to use only
RO/DI water for make-up/top-off water. Use of activated carbon can also help
keep this level in check. Copper is fatal to marine invertebrates at levels as
low as 0.05 mg/L for many species.
Alkalinity (meq/L)
Natural Seawater Value: 2.5 meq/L
Acceptable Range: 2.5 to 5.0 meq/L
Tested: 4.26 meq/L
(GOOD) Your alkalinity level is within the recommended range. We
recommend continuing with your current water change and buffering
schedule. Maintaining an appropriate alkalinity is crucial to maintaining a
healthy aquarium. A fluctuating alkalinity will lead to serious problems in
maintaining an appropriate pH, as well as problems keeping calcium and
magnesium levels within required ranges.
