I began the process of bringing the anaerobic bacteria culture online as directed in the Deltec Manual. The Deltec NFP509 Nitrate Filter feed pump was to be turned off for a period of 3 days to isolate the water within the reaction chamber from the rest of the system. The internal re-circulation pump is still functional but this process allows the oxygen within the water to decrease and provide the ideal environment for the bacteria to grow. I was originally using the Deltec Peristaltic Pump to feed the reactor, but soon discovered that I could not not control the level of flow and determined that to be a huge problem. I also was not able to locate another aquarium grade peristaltic pump that could meet the future demands on the flow of water through the Deltec NFP509 Nitrate Filter due to the tubing on the injection port. Well sometimes you just have to go back to simple. I decided to pick up a Tom's Aqualifter Diaphragm dosing pump and using a control valve I'm able to regulate the proper flow of aquarium water thought the filter. Note, that the tubing on included on the Deltec aquarium water feed port is slightly larger than standard airline tubing which gave me a nice surprise and dosed my 3 day oxygen deprived water with tons of air and left my with a nice cleanup because the check valve I used to initially feed the pump just fell out. I solved this problem by removing the tubing that came with the Deltec NFP509 Nitrate Filter and heated up some regular airline tubing and connecting it that way. The fit is tight and it definitely wont come off again without a fight.














[
















Deltec has a few different methods in which the Deltec NFP509 Nitrate Filter can be operated. I was originally going with the manual method where I would be responsible for not only dosing the Nitrate Fluid (1 Part Vodka, 3 Parts RO/DI Water) twice a day but also manually adjusting the flow of aquarium water into and out of the reaction chamber. This was done using a standard syringe and it was time consuming. Every morning and every evening I would measure the fluid out, inject the fluid, clean the syringe,put the nitrate fluid away and close up the stand. So with the fact that I work about 20 hours a day most days I needed a better option. So I went with the recommended semi-automatic method where the fluid is feed into the reactor using a dosing pump. I didn't own a dosing pump ad there were many on the market to choose from. So I did some research and visited a local reef ship in Connecticut and purchased the Jebao DP-4 Automatic Doser for this purpose. Now I normally go for the best money can buy. But in all honesty I also don't like throwing away money for no reason as well. And I couldn't pass up the great reviews and accuracy that this dosing system received. So far I have not been disappointed with it and I will create another post to review it alone. Deltec Recommends that the doses in manual mode be administered twice a day. but now with an auto dosing system in semi-automatic mode if is recommended to spread the dosing amount per day within 4 doses for a more stable environment for the bacteria. I am now currently dosing 2 ml of Nitrate Fluid every 6 hours for a total of 8 ml of Nitrate Fluid a day and I couldn't have done it without my doser!

A day has passed since I started the feed pump to the reactor and allowed the effluent from the Deltec NFP509 Nitrate Filter to flow back into the aquarium at a rate of 1 drip every 3 seconds. I used my nitrate liquid test kit to measure both the levels of nitrate from the effluent and the water from the display. Honestly I was shocked to see that the Effluent was the brightest yellow I have every tested. The display obviously still shows nitrates being detected at 10 ppm. Unfortunately, this is attributed to the fact that I added a Tiger Tail Cucumber to my aquarium and died after acclimation. I however was only able to removed half of the body. The other half is wedged inside the base of the rocks. But back to the main topic. The Deltec NFP509 Nitrate Filter works... and works well! I am also monitoring the reactor with my Neptune Systems Apex Controller. As long as my ORP level reads 0 then were good to go!

Thank you and yiur welcome. I figure the more I share the more the community of reef keepers can benefit. I personally hate looking at a product and not finding enough useful information and real world experiences to allow for a good decision to be made of wether or not the item can work for your specific needs.

I know it has been a few weeks since I have been able to post something. But I just wanted to ensure everyone that the aquarium is doing well. Here is a tank shot during the evening hours of the reef.

So one of the key components required to run the Deltec NFP509 Nitrate Filter properly is the Nitrate Fluid. What is this magic fluid? Its just a simple mixture of 1 part Vokda (not flavored Vokda, I used Smirnoff) and 3 parts purified water, preferably RO/DI water. Feed the Nitrate Fluid into the reactor starting at 4 ml twice a day either manually being injected using the included syringe or via a dosing pump if you prefer to go automated and the anaerobic bacteria inside the reactor will love you! And in return you will get nitrate free water (once the bacterial population is large enough). But you will need a storage container to keep your mixed fluid. I didn't go the route of having a fancy dosing vessel. My wife is into canning so I liberated one of her Ball Mason Jars and used that to mix and store my nitrate fluid.



A simple Ball Mason Jar for mixing and storing my Nitrate Fluid.



3 parts of RO/DI water.



1 part of Smirnoff Vokda added to the 3 parts RO/DI Water.



Mix it up and you have your Nitrate Fluid.




I initially was manually injecting the Nitrate Fluid into the reactor once at morning and once at night. I work pretty much most of the day. So this began to be a little troublesome to me. So I decided to setup my reactor in the semi-automatic method and use a doser to inject the nitrate fluid for me. I drilled a hole through the Ball Mason Jar lid large enough to put silicon airline tubing through and purchased a doser to do the job for me. I now have more precise control than I could every have done myself and I inject 1 ml of Nitrate Fluid 4 times per day. The doses area spread out more frequently in smaller amounts to provide for a more stable bacterial colony.
