- Xport-NO3 Biological Filtration Dimpled Brick - Brightwell Aquatics
Dimpled Brick Dimensions - 9.0" x 4.5" x 2.625"
The dimples allow for water flow to pass through when a single brick is placed on the bottom of a sump, or when multiple bricks are stacked one on top of another.
Xport-NO3 is great for tanks that have minimal aquascape, or are heavily stocked. The biomedia plates can be put just about anywhere within the system to allow more surface area for biological filtration, resulting is faster conversion of nitrates. Denitrifying bacteria will colonize on surfaces within the aquarium, and by adding more surface area will give the bacteria more space to flourish resulting in lower overall nitrates in the aquarium
Brightwell utilizes NanoIntelex technology creating a highly superior biomedia that has vast amounts of surface area that will allow beneficial nitrifying bacteria to colonize. Xport-NO3 works with all types of saltwater aquariums and can be employed in just about any fashion that doesn't tumble the cubes.
Xport-NO3 is a superior biomedia that utilizes NanoIntelex technology allowing Brightwell to create one of the best, most adaptable denitrifying biomedia cubes on the market today. Made specifically to allow beneficial denitrifying bacteria to colonize within the vast amounts of surface area within the cubes internal pore structure.
- Utilizes NanoIntelex Technology to create an enhanced, "ultra-activated" material with the capacity to outperform conventional denitrification media by over 300%
- Open structure and high surface area results in superior flow-through characteristics and filtration efficiency.
- Higher efficiency relative to conventional media results in smaller space requirements to achieve equivalent denitrification.
- May be employed to rapidly decrease nitrate in even the most heavily-stocked systems.
- Eliminates the need to perform water changes that are carried out for the express purpose of decreasing nitrate in an aquarium system.
- May be used in conjunction with Xport-BIO and Xport-PO4
Instructions and Guidelines
Read all instructions before use. The use of a mechanical pre-filter to remove particulate organic material from water prior to its interaction with this media will improve efficiency. Rinse Xport-NO3 in purified water or low-TDS fresh water, then place media into a clean pail and fill with water from the aquarium into which the media is to be placed. Seed each 150 g of Xport-NO3 used with 20-ml of MicroBacter7 (poured into the pail and dispersed by hand), then allow media to remain in this "bath" for 24-hours at room temperature. Remove Xport-NO3 from pail and pour water into the aquarium system, then place Xport-NO3 into canister filter, media reactor, or 800µm mesh filter bag; a flow-through rate of 1 - 3x the total aquarium volume per hour is recommended. Do not fluidize. In systems with an initial [NO3] of <40 ppm, begin with a ratio of 150 g Xport-NO3 per 120 US-gallons (454 L) in system (increase this mass by 10% for every 10 ppm NO3 in excess of 40 ppm). Denitrification will typically begin within one week; rate of denitrification increases with time. If corals or other invertebrates appear to react negatively to the use of Xport-NO3, it may be an indication that NO3 is being removed too aggressively; decrease amount of Xport-NO3 used by 50% and continue use until [NO3] falls within desired range.
Note that the required amount of Xport-NO3 will change as the system matures, and as biomass and/or stocking density changes. Denitrification relies on adequate organic carbon availability; if [NO3] stops decreasing during the first month of use and no significant increase in bioload, stocking density, or nutrient input rate has occurred during this period, then it is likely that organic carbon or phosphate is limiting. Use of Katalyst, Reef BioFuel, or FlorinAxis (planted aquaria) per the instructions on the respective labels will be required to provide this carbon; NeoPhos or Florin-P will provide phosphorus. Replace ~25% of the total Xport-NO3 employed every 3 - 4 months in high-bioload systems, and every 6 - 8 months in low-nutrient systems. Maximum rate of denitrification is achieved by placing Xport-NO3 in-line with, and downstream from, Xport-BIO. Xport-PO4 may be used downstream from Xport-NO3 to facilitate complete phosphate uptake; do not place Xport-PO4 upstream from Xport-NO3, which will inhibit denitrification.
Excellent nitrate removal By Reefdad on 2/29/2020Reefdad would recommend this product to a friendI cut the block in half for my 40 gallon breeder, followed directions to pre-seed with microbater overnight, and watched nitrate drop from 20 ppm to 2 ppm over the course two weeks. Now I'm stable at 5 ppm after two months of daily feeds of: 1/8 tsp reef-roids, 1 - 1 1/2 cube frozen, 5-10 drops of brightwell aminos.
Caveat: harmful to photosynthetic sponges By Mike on 11/24/2019Mike would recommend this product to a friendWithin days of introduction to my tank, my purple photosynthetic sponge melted away (it had grown to 8 inches across over the process of one year). Removed the block and and the sponge eventually regrew. Pretty sure the block is responsible as the sponge has been stable and growing since that incident.
Breaks apart after several months By Jason on 1/13/2019Jason wouldn't recommend this product to a friendWell, despite the reviews I decided to give these a try. After being tucked away in my sump for 4 months, I began to notice what looked like beach sand on the bottom of my sump and inside my protein skimmer. The product performs well, but unfortunately it does not stand the test of time. Pieces began to fall apart and just turn to a heap of crumbs.
Has worked awesome for me By Fourthwind on 10/22/2018Fourthwind would recommend this product to a friendHas remained solid for me for 9 months. Absolutely no problems with Nitrates in a heavily stocked tank. One problem people may be having is that this brick is made for LARGE tanks. I would not recommend in tanks less than 100 gallons as the bacteria in the brick will not have enough food, Use the cubes in smaller tanks.
undetectable nitrates with no waterchanges By dulgee on 9/12/2018dulgee would recommend this product to a friendthe brick held together for me in the last 9 months, it is still solid. i have it in a low flow area in my sump with an xport BIO brick sitting on top of it where the flow is higher. i have not seen ammonia or nitrate in 9 months. I recently added a handfull of the xport PO4 cubes, and now i cant measure any phosphates either. I assume the encrusted ferric oxide will eventually be used up, and I will need to change out the cubes, but so far so good.
works great for me By David on 4/10/2018David would recommend this product to a friendI've had two in my sump for 18 months and they have not broken down at all. Nitrates are very low despite heavy feeding and a moderately high bio load. I won't run a tank again without at least one of these in my sump.
no issues By mark on 9/12/2017mark would recommend this product to a friendI havent had any crumbling issues with this product. It is easy to damage , i keep it out of the way in my sump so it doesnt get rubbed / hit. I feed pretty heavy and my nitrates are < 5. I dont dose any carbon. I have had this from start of my tank, so I cant say for sure if it responsible for nitrate reduction.
The easiest way to reduce nitrates By emmbec on 8/24/2017emmbec would recommend this product to a friendI've had this product for almost a year now so I can say with confidence that this product does work well. I've had no issues like others have said that it crumbles appart, I heared there was a bad batch but they are being replaced so I think I got the good one. I would highly recommend them to anyone wanting to reduce their nitrates in a natural and easy to use way.
Dimpled brick Positive results in Nitrate Reduction By Andrew on 2/20/2017Andrew would recommend this product to a friendI saw a reduction of nitrates in my 115 gallon , heaviky fish stocked and heaviky fed system within 1 week that seems to have leveled off after a month's use. I have been using this product for several months now. While I do have other Nitrate Reduction methods in use as well, this was the last one put into place. It reduced my nitrates from a consistent teens reading to a consistent 4.
