Would a brs dosing pump be a good pump for this application so as to not create hydrogen sulfide?
Thanks.
So is this basically a fluidized sandbed filter of old, with added bacteria to feed it? Lifeguard Aquatics still makes them and can be modified most likely.
Another member on here, who unfortunately passed away earlier this year, came up with his own DIY Nitrate Destroyer. He used 2 pvc pipes (first pipe was in-flow at the top, the second was fed from the first at the bottom and exited the top) and filled them with a mix of all different shapes and sized medias. The slow flow rate enabled aerobic bacteria in the first chamber to form and allowed anaerobic bacteria in the second chamber to gas off the nitrogen that formed to eliminate nitrates.

Please add some links to the pumps if you know where to find them. Would really like to find more controllable pumps 10-100 l/h.The BRS dosing pumps are not rated for a continuous duty cycle. You are into Masterflex and Watson Marlow pumps for this type of use (or plan for pump failure and keep spares).

I like it.Hi guys..... Idk how the tech over in the west has developed, but I have used this system for quite some time already. Its pretty similar to the Dymico system but I made it much simpler and added an algae reactor to raise the pH. I designed it myself about 3 years ago and the test tank ran for 2 years before I moved house and started a new tank (4k L tank)
here's some pics of the tank in early 2015
And here is the tank in late 2016.
All corals as you can see are grown from frags. Mortality was very low with this tank and I could even raise gorgonians and some NPS without any problem.
The main reason I did this tank was because of the "skimmer craze" here in Thailand a few years back where everyone was trying to sell skimmers like they're hotcakes or something. I wanted to see whether it was possible to have a system designed and maintained without using a skimmer at all. This system was the result. It uses an active deep sand bed (I call it an aDSB) for main filtration and a chaeto reactor for secondary filtration.
again, ran this for 2 years, no problem whatsoever. Only problem was it ****** off alot of people that it succeeded.
Did you inject co2 to utilise it as a calcium reactor as well as nutrient export?Hi guys..... Idk how the tech over in the west has developed, but I have used this system for quite some time already.

There draw back of dymico is cost, and not simple enough. Give it time, when microprocessor fails (with time), won't be fun. Personally. My denitrator on dt, simply 5 gallon bucket, I use clay 1/8" size. water enters top. With pump(dedicated to it) in refugium,pump keeps recirculation , let gravity do its job. Works fine. I use to use sulfur denitrator, but it effects calcium, alkalinity, etc....
The clay is cat litterWould love to see a pic of this (the 5 gallon set up you mentioned)!
I use a set up like that in my sump . So water flows through my ruble rock .. instead of just over it .
For tight packed sand you have to do some testing for size of the pipe . A valve or a pump that would let the water flow once or twice a day . Like the shifting currents of the ocean would do .
Otherwise you would just be making a huge fluidized bed filter .
