The followup video is here th-cam.com/video/wNuurov-llw/w-d-xo.html Notice at 2:45 from the side view that the amount of bubbles in the up-tube was drastically reduce from the first video. Also It appears the second up-tube was removed. One up-tube is all that should be used no matter what the size of the plenum, for minimal movement of the water through the substrate.
Anybody watching this old video after searching Anoxic Filtration, please don’t follow this setup, it’s completely incorrect. By using an air stone to draw tank water threw the substrate he has built a standard under gravel filter using normal bacteria. To understand Anoxic filtration read the paper produced for Koi ponds by Manky Sanky
Just a heads up.....the fabric you are using is falsley advertised as breathable. It maybe in the open air, but many astute lanscapers can tell you it gets blocked up very quickly creating an anaerobic calamity. The only reason Dr. Novak suggested it's use is primarily for aquariums who have plants that need soil. You do not. {The good doctor does not have any experience with plants so that bit can go in the can.} Also, you do not need a thick layer of the red substrate or kitty litter if your using decorative gravel. A 1/4 " red & Grey clay is enough. The concept is to have minimal oxygen going through the gravel bed at a slow rate to help grow the rare bacteria that also need to feed on iron (just to get started) The UGF plate is only a chamber sorta like a nursary, it's not to be used as a filter. Having a tube or vent pipe in one corner, (1 or 2 inches long is all that is needed) it will act as a vent for the heat created by the bacteria. This then sets in play a convection system, the suction from the top of the gravel downward with the right amount of oxygen....Too much O no good bacteria, not enough, you get bad bacteria. Sorry if this is long. it's just that, the bacteria that this whole set up is for, happens to be very fickle and i don't want to see time, energy, and money wasted. Hoping for the best.
I dont think are you ment to hook up the under gravell filter as it is there to act a plenum? Running or forcing oxygenated water through the substate will not alow it to become a Biocenosis Filtration System as it needs to be anoxic no or very low oxygen. Thats why BSB are placed in the sump so water can flow around it not through it,. Water seaps through the BSB creating a low oxygen enviroment for the anoxic bacteria to grow and do it's magic which is what the plenum dose. You need to go back and look at Dr Kevin Novak Channe again as he shows how to set up a plenum and substrate, he dose not hook up any thing to draw water through it like you have with the air lift tubes. I could be wrong but as my tanks are set up with plenums set up like Dr Kevin Novak Channe describes and BSB in my tank with a sump they all have very low to no nitrates. I will be very interested in you results a couple munth down the track as it took mine about 2-3 months before I saw a real reduction in nitrates going from 60-80 ppm to less then 5ppm sometimes 0ppm as my tanks are heavily stocked.
MrGrantdw, thanks for you comment 👍👍. Indeed, low oxygen is what I need . However, in one of Dr. Novak video were he explain the use of sand as substrate, he allows the use of the filter but just half of the tube for minimal flow. I had some technical difficulties because the air stone is adjusted on the top of the tube so I can just use half of the tube. I was thinking to rise the stone but I think it does not change much......still working on that . I don't want to removes all flow. Even in sumps you have some flow. I am considering two options: one excavate and cut the tube , two lift air stone half way up in order to see if flow gets reduced. Again thanks for your comments 👍👍👍👍
In Dr. Novak's Video "Denitrification Testing of 30 aquariums, The results will shock you.": Pay attention to what he says happens, (Starting at 06:15), if the flow rate goes to zero. So what he recommends in some of his other video's Specifically Regarding the Plenum Approach (As opposed to BCB's) is Extremely Low flow rate of 1-2 Gallons Per Day. ..Basically, the Bacteria need proper 'Flow Dwell Time' for processing/conversion. And Either too high a flow rate, or Zero flow rate, defeat that.
Just buy Seramis plant ceramic granulate. It is already baked clay and high iron content. Cost nothing in comparison to that very rare red clay in pet shops which cost a lot for a small amount.
Cut off the air to the under gravel filter and just place a sponge filter on top of the colored gravel with airline...that will fix this setup and make that under gravel setup anoxic.
Bipolar aquatics, thanks for suscribe to my channel. I still having water changes every 2 weeks at 30ppm nitrate. I have 0 ammonia and 0 nitrites. I currently have 5 guppies in this tank. I would consider this filter a success when the max nitrate level is below 10ppm nitrate. I will make another follow up video when that happens , I will wait one more month.
Great video. I have a 8 year old son and can totally understand your choices ,☺️

He just needs to make the air lift pipe very short : HIS TANK'S SUSTRATE HEIGHT.
i agree it’s completely incorrect

yeah, this is not what novak prescribes. i will say that novak is extremely poor at explaining things, but still.

Good video. What's with the Skittles gravel? LOL
Don't you want to keep feeding it ammonia?

Old water is of no benefit
I used to do that all it does is dirty up new water
Your lift tubes are way too long. 2 inch tube is tall enough so you get minimul flow otherwise your system will clog and fail eventually.
Still would be interesting experiment new sub

@@myaquarium2514 I hope you reduced height of the airlift.
That's just an undergravel filter.
Why not use flourite on the top instead of that clown puke gravel?
His son likes it.
