Thank you for your business! Please let us know if you have questions, comments, or concerns.
Please remember that the information that accompanies your tested values is a courtesy and is offered only to frame the results in a way meaningful to the aquarium hobbyist. The NSW values, acceptable ranges and recommendations are not meant to replace the advice of aquarium professionals and experienced hobbyists.
Ammonia (NH3-4)
Natural Seawater Value: 0.010 mg/L
Acceptable Range: 0.000 to 0.050 mg/L
Tested: 0.003 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: 0.011 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: 1.4 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: 0.05 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: 0.2 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: 343 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*
*These values represent only the amount of free calcium ions present in the samples. According to Randy Holmes-Farley, the total calcium concentration can be 10% to 20% higher.
Tested: 356 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: 1.3 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: 0.1 mg/L
(GOOD) Your molybdenum level is within the recommended range. 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. Your level is below this limit and is in proximity to natural sea water values. Molybdenum is important to microbial activity in the aquarium filter, and may also be important to stony coral health and reproduction.
Strontium (Sr)
Natural Seawater Value: 8.1 mg/L
Acceptable Range: 5.0 to 12.0 mg/L
Tested: 9.3 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: 1375 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: 0.11 mg/L
(HIGH) Your iodine level is too high. We recommend a reduction in chemical additives containing iodine. You may also wish to reduce the feeding of any shellfish-type, or red-algae based feeds, and increase protein skimming. Iodine is known to be required by many soft corals, marine macro algae, and is a component of many of the colorful pigments in stony corals. Iodide is a strong oxidizer however, and an overabundance can damage coral tissues, and has been implicated in algal blooms.
Copper (Cu++)
Natural Seawater Value: 0.030 mg/L
Acceptable Range: 0.000 to 0.030 mg/L
Tested: 0.03 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: 2.39 meq/L
(LOW) Your alkalinity level is too low. We recommend the addition of a commercial buffer designed to raise alkalinity. You may also wish to perform a partial water change to help correct this issue. Maintaining correct alkalinity levels is critical to corals, as well as any shelled invertebrates, including snails, clams, etc. It is also crucial in maintaining appropriate pH and calcium levels. This is one of the most important parameters for the maintenance of marine aquariums.
I have ok coloration, growth is slow to ok. I get RTN from time to time on newly aquired frags.(They slowly use color/brown and then rtn after a week or so on the underside of the frag.) Sometime it stops and recovers and sometimes it goes all the way.
10 cardinals
3 small anthias
1 - 4" blue tang
1 - 4" purple tang
I think i keep my system stable. temp never fluctuates more than 1/2 degree in 24 hours (80*)
Salinity 35ppt
I have short but dense green algae that covers the back and side panels. I little to no coralline algae growth on the glass or pumps. I scrape it off with a razor blade and it looks like nori when its flying around the water column.
I am running 400 ml pellets (weaned off vodka and gfo onto the biopellets)
TANK is 120
with 40g sump
I change 5g every 5-7 days with same temp and same salinity water (brightwells salt)
approx 90-100g in tank and 20 in the sump.
