Here are some photographs of my happy fish.

 

So within a few weeks I noticed a very significant drop in the calcium levels within my water. The readings were almost 60 ppm apart. Well most of my rock are covered in spots of green, ,maroon and pink coralline algae that seems to be developing at an extremely fast rate. I mean its literally over all the rocks. All I can say is I'm happy! I took one photograph with the flash... you can see the corallin algae more like that.

 

Over the past few water test I notice that my nitrates have been a steady 10. This I might be able to contribute to the daily feedings of a whole cube of Frozen Mysis and the filter socks catching all that food when some of it goes down the overflow. I'm also not a huge believer in massive water changes. So I decided to give Deltec's NFP509 Nitrate Filter a try. The premise is simple. What full of Nitrate and Phosphate is slowly run through the Deltec NFP509 Nitrate Filter. This slow flow creates an area of very low oxygen which provide a place for the anaerobic bacteria that feed on the Nitrate and Phopsphate to populate. Combine that with a carbon food source (Vodka) and out comes nitrate free water. I just started the process to begin the population anaerobic bacteria growth. So the main feed pump has been turned off and only the re-circulating pump is running. I will also be providing the bacteria with the food a mixture of 8 oz RO/DI water and 2 oz of vodka injected into the reactor with 4 ml twice per day for the next few days. So I will keep everyone posted on how this goes.

 

Very cool jay. Try turning off your main pump while feeding, it will help keep that filter sock cleaner longer. I'm curious to see how the deltec goes for you. Keep us posted. If your not big on water changes then make sure you dose that tank to keep the big three stable. Congrats on the purple growth.

 

You should do a thread with just a product review on the Deltec's NFP509 Nitrate Filter.

So I take it you're going for the ULNS?

 

You wanted it you got it!

I have been religiously testing my aquarium water every week without fail. And I have noticed that my nitrates after my cycle have been constantly at 20 ppm for the past few weeks. I can attribute this most likely to the daily feedings of frozen fish food and my filter socks. I'm also not the biggest fan of doing large water changes but that is a completely separate topic. So I need to find a way to reduce my nitrates without using exhaustive media that needs to be replaced frequently as my work schedule would not allow for such things. The answer that I may have found might just be the Deltec NFP509 Nitrate Filter. In a nutshell this little piece of equipment provides a place for the anaerobic bacteria that is responsible for utilizing nitrate and phosphates (from my reading) as part of their food source along with a carbon based fluid (1 part Vodka, 3 parts RO/DI) as their food. The result a Nitrate and Phosphate removing group of bacteria that can put a smile on my face. So lets see if this thing actually works.










Assembly of the unit was simple It consist of just attaching the included Aquabee recirculation pump to the platform at the top of the body and connecting the water exit fitting. There is an included Probe Port that will allow you to install an ORP from your manufacturer of choice. This is an absolutely necessity in my opinion as it will allow you monitor the oxygen level present within the water inside the chamber.
















You can bring water in from your aquarium sump to the Deltec NFP509 Nitrate filter in a variety of methods. Besides the pump you will find two tubes (one with a built in check valve, which is used to feed the reactor with your nitrate fluid). The other is used to allow water from your aquarium to be injected into the reaction chamber fed by the recirculation pump. In my opinion their should have been a check valve here as well as I will elaborate on later on.




I choose to feed mine initially using a Deltec Peristaltic Pump but eventually discovered that the slow rate of feed would hinder operation once the bacteria colony grew and my water flow level raised to accommodate this growth.








I installed the Deltec NFP509 Nitrate Filter underneath my aquarium stand next to my sump and connected all the fittings.










I went through the entire recommended process of starting the culture. Which involved adding water from your sump and then shutting off the feed pump to the Deltec NFP509 Nitrate Filter to isolate the water to bring the oxygen level down over the course of three days. During this time the recirculation pump is still running and you will be adding a dosage of nitrate fluid (1 part Vokda and 3 part RO/DO Water) twice per day and this is based on your device size so mine was 4 ml of Nitrate Fluid twice a day. During this process I monitored my oxygen level drop from 200 to 64. You will continue doing this until the 3rd evening at which you will turn on the feed pump and adjust the flow to 1 drop every 3 second from the Deltec NFP509 Nitrate Filter. You will continue this every three days slightly adjusting flow and the nitrate fluid used while you measure both the nitrate level from the effluent and the aquarium itself. The idea is to get to a flow where your aquarium nitrate is zero and the effluent is zero and stay feeding that amount of nitrate fluid.

 

Well thanks a lot. Great job! I am really interested in see how this works out even on a young tank.

 

I will definitely keep you and everyone else updated!
