ronreefman, September 7, 2011 in General Info. A. VANDENHWDT. Unlike other nitrate reactor products, the Aquaripure nitrate reactor filter (or denitrator) is designed to be safe, extremely easy to use, require little maintenance, and completely remove nitrates for many, many years. I have it on both of my systems. De*Nitrate on the bottom, a bag of carbon and a bag of PhosGuard on top of it. Amquel Plus is a Unique Water Conditioner Providing Actions Needed For Safe aquarium and Pond Keeping For Fishes and Invertebrates. Here is one by AquaMaxx. Feeding and adjusting the Aquaripure nitrate reactor only costs pennies and will only take seconds of your time. Basically, the Large Aquaripure is equal to 8 gallons worth of other denitrification media set up in it’s own reactor, depending on flow rate and other factors. Includes pump, tubing, feeding syringe, and manual. Powered by Invision Community, SouthWest Florida Marine Aquarium Society. Don’t be fooled by the cheap nitrate reactor products or denitrators. This is my 2nd water change (25g for a 400g system) since the reactor shut down. Allowing filter media to be optimally utilised and preventing channelling and inefficient use. A nitrate reactor that I built for my 75 gallon african cichlid tank. Recommended for Aquariums between 55-115 gallons (200-435 Liters). High capacity: The pump in the TORQ® Dock has a high maximum flow rate of up to 1.000 l/h (264 gph). Aquaripure’s nitrate reactors are designed to be easy to setup and maintain, and will give you many years of service. There are however ways, such as a nitrate reactor, to reduce the nitrates in the aquarium without water changes. Typical breakthrough curves of nitrate and nitrite measured in the outflow of a flow-through reactor are shown in Fig. As expected, with decreasing flow rate, the increased water residence time in the reactor resulted in more nitrate consumption and, thus lower outflow nitrate concentrations.Over the range of flow rates tested, the steady-state nitrate reduction rates varied from 102 to 180 nmol cm − 3 h − 1 (Fig. W. BAEYENS Laboratorium voar Analytische Scheikunde Vrije Univet"'siteit Brussel, Belgium.Abst"ract Nutrient uptake rates of natural phytoplankton taken from the Belgian coastal area have been assessed. Includes pump, tubing, and instruction sheet. All any aquarium really needs for great water quality is good water flow, a little mechanical filtration, and an Aquaripure nitrate reactor. With Aquaripure nitrate reactors, no sulfuric acid or sulfates are produced and nothing will ever need to be replaced. As the nitrate reduces to zero it is very difficult to back off the reactor as they have plenty of food available. Nitrates are a nutrient. And thanks for the follow up on flow. Display as a link instead, × Jay, or anybody who knows, The pump on my RocDoc nitrate reactor died and the clear hose had become very green with algae. There are products such as Amquel Plus which bind the nitrates and will provide a “quick fix.”  Although it is not a nitrate reactor this product can help alleviate sudden nitrate spikes. So I took it out, flushed it with fresh water and some bleach, emptied it, flushed it with RO water, emptied it, flushed it with salt water and now it's ready to go back to work. Only a specialized nitrate filter like Aquaripure nitrate reactor filter (denitrator) can provide permanent and complete nitrate reduction. Aquaripure’s nitrate reactors are designed to be easy to setup and maintain, and will give you many years of service. Flow rate (L/day) 16.2 16.2 Flow direction Up-flow Up-flow HRT (h) 5.2 14.8 Reactors were operated in an up-flow mode. Increase flow to reactor to 1 drip per 2 seconds for a further 1-2 weeks or when the nitrate level again read 5ppm. It’s not even available at the time I posted this! Flow rate should not exceed 200 L (50 US gallons) per hour. Nitrates? jaewoo@korea.ac.kr Using the Large Aquaripure will be the equivalent of up to a 90 gallon weekly water change. In other words, it will be it’s own dedicated nitrate reactor otherwise it acts just like bioballs or any other biological media. But I don't remember the flow rate at the outlet. At that rate I'll cycle all my entire system thru once every 8 days. Aquaripure nitrate reactors all have a tremendous internal surface area for denitrifying bacteria to grow and thrive, much more than any “coil” nitrate reactor or the other competition. I have a steady stream that breaks into droplets about 2-3" below the outlet. Nitrate recirculation flow rate has long since been identified as a manipulated variable in a predenitrification system (Olsson and Jeppsson, 1994). Two-in-one: One reactor, two media – In the TORQ® bodies 1.0 and 2.0, it is possible to use two different filter media at the same time by inserting a chamber separator. Unfortunately with the amount of LR I have in the DT and sump, plus the DSB, I have had zero nitrates for the last 2 months even though the reactor wasn't running (I've had zero nitrate for months with the reactor as well). 12 (B) ... Methanol often dosed to increase denit. 5 litres per hour or where the nitrate level ceases to drop Save Time and Money, Eliminate Nitrates, Control Algae, and Reduce Maintenance!   Pasted as rich text. Now I have a new question, as the anaerobic bacteria build up, assuming they find any nitrate to use as food, just what exactly is it I should be testing the effluent for? aragonite needles can be broken to shorter needles by mixing or grinding. Unlike other filters in which you have to replace the internal media, you will never have to change anything on the Aquaripure nitrate reactor filter (denitrator). Here is one such typical imitation product. The Aquaripure nitrate reactor filter (or denitrator) uses beneficial bacteria to break down invisible organic matter and nitrates completely into Nitrogen gas which then escapes into the atmosphere. 10). The media contained within the reactor can then begin to absorb the unwanted nitrate. Is that too fast, too slow or Goldilocks? Denitrification rate increased with the increased initial alkalinity and was approaching saturation when initial alkalinity exceeded 2.5 times the theoretical value. Also, Aquaripure has 14 years of experience to draw from and so you won’t be on your own trying to figure out the necessary parameters, media volume, and ideal flow rate for your aquarium. × With an alcohol fed system you must feed it every day but then when it is matured and has done its job you can control the amount of bacteria by the amount of food and the flow rate that you use. If you dial them down to the appropriate gph, they will strip your nitrates from your tank without the sulfur. I'm only doing water changes for the trace elements, not to remove nitrates. No, you are right and that is a good point! It is completely harmless to all freshwater and marine aquarium fish. In flow-through or continuous reactors the feedstock residence time refers to the time that the feedstock particle spends in the hot reactor zone and subsequent hot pipework. Everything is ok though and I haven't lost any stock. × Materials and Methods—Growth chambers (reactors)—These (Fig. Also, the costly sulfur and carbonate media must periodically be replaced. I run one in a home made pvc setup and the other is in a two little fishes reactor. All the organics in an aquarium is broken down into nitrates and they will normally remain nitrates until they are removed by water changes. 16 2ary ANOXIC … It is best to rinse off dust before use. Rebalance the reactor at this point and try to maintain your nitrate level at 1-2 mg/lt and certainly less then 10 mg/lt. The ammonium and nitrate eliminated by the GAC-USRs were calculated using the following equations: 15,16 Nitrification rate:(1)Denitrification rate:(2)Where R is the wastewater flow rate, V is the reactor volume, [NH 4in ] is the influent and [NH 4out ] the effluent NH 4 concentrations (g NH 4 -L), and [NO 3in ] is the influent and [NO 3out ] the effluent NO 3 concentrations (g NO 3 -L). Once de nitrate™ has been in use for several days, nitrate concentrations should start to fall and level off gradually at a concentration of about 4–5 mg/L as nitrate.
