I've just been looking at Fluval Stratum. Here in Indonesia it is priced at about $300 per 17.6 pound bag. Checked out the description and it looks like I can use a locally available alternative which is also sourced from the foothills of a volcano. It is called "pasir Malang", which translates to "Malang sand" and can be had in red or black, coarse or fine for about $1.30 per 5 kg bag. If you are based in Indonesia it would appear to be a cost effective alternative. The undergravel filter panels shown are also available locally with both plain panels and panels with a hole set up for a riser tube. They cost about $0.70 cents each in black or white while the risers are sold for about $1.40 each. Unfortunately the risers are fairly large but I feel that with the air supply adjusted properly they could be usable.
Wanting to do a Plenum Build for my 12 Gallon. Could I use a Fine Silicone mesh to place on top of some bio media? Im going to be using Sand to go on top.
I'm curious how you will inject the negatively charged ions which I think are necessary for the anoxic filtration process? Also, pond stores sell calcium montmorillonite clay powder used to feed goldfish to enhance their color as well as polish the water. This same clay is added to Dainichi cichlid pellets to enhance color and digestion. Would adding this clay powder to the water per the directions provide the negative ions in the substrate filter so that anoxic filtration could be carried out on the plenum without using kitty litter? Thanks!
Cool update, will just get better as the series goes on, very interesting one. Fun to see you get into the scaped tank market a little more, trying the new plant light and soil, plus CO2 is in the works! One of my tanks has the 3.0 and stratum. I’ve been happy enough with it over the past year. I would suggest using your ground cover method on top of and around the UGF. This will keep it from shifting underneath it around the gap at the edge as it shifts around easily in the beginning. Also, it has done a pretty decent job retaining its granules up to this point. Some powdered and shifts down through the substrate, although, it’s been more than adequate and better than some others, in that sense. Most are similar to original size, yet the cover will also help any that does break down now slip through the UGF too. Not my favorite soil, but still very decent. I think lighting can be as intense as you want or plant species can handle so long as you balance everything else to the same level. I think strong light intensity is hardly ever people’s issue, it just presents their already under lying issue more rapidly, so turning it down makes them think it’s helped. Interested to hear updates on your experience about this. If it seems to have no negative affect, next I really want to see what messing with the spectrum does for you. It would be nice to know if the low 5% blues is necessary or if an increase triggers anything.
That is good to hear, always open to good info on the Fluval Stratum. In fresh water aquariums PAR is not that important as LUX and K values. Very strong light with very little Blue spectrum and cutting back on the Red's too will make a big difference in plant growth and inhibits Algae growth.
Looking forward to see your 90g tank setup Dr. Novak. I agree 100% on the costs of Chemipure. I searched for laterite on Amazon and you are right, it's now available in clay form...but it wasn't earlier when everyone was trying to find it to make the BCB baskets. Your plenum is really the best way to create anoxic conditions without the use of a sump...under gravel filtration is excellent. Fill it up with a porous substrate with a layer of laterite and your in business. It should be noted to those watching that you don't want to use an air pump to push oxygen through the substrate. That will prevent the substrate from becoming anoxic.
Fluval Stratum was $25 for an 8 pound bag the last time I bought it. I have 2 of the Fluval Plant lights. I think they are great and reasonable for the quality. I'm setting up a 75gal tank using an undergravel filter as a slow moving plenum as you suggested. I have a deep substrate with saf-t-sorb over the filter plates. Then I have a thin layer of fluorite red and then a thin layer of Fluval Stratum and a thick layer of ecocomplete. I plan to put some more Fluval Stratum where needed for the plants. My tank is cycled now. I haven't done any water changes. My nitrate is 5ppm this morning. I expected it to be 80ppm or more. I don't what caused this. It's been 3 weeks since I set it up. Do you think the anoxic bacteria is established already or maybe it's the saf-t-sorb? Anyway, I'm happy
How can you end up with anoxic conditions in the substrate when using a plenum or UGF? Oxygenated water is constantly flowing through the substrate and back out the lift tube(s). You would need a dead zone with no water flow which then would be deplete of oxygen.
From what I understand .The key is a slow flow rate. When the flow is slow the oxygen gets used up before it reaches the bottom part of the substrate. The plenum is just used to move water slowly through the substrate to allow lower oxygenated water in the plenum
I’m studying Ions, protons, electrons neutrons of atomic structure of a atom And when you bring the ions in, is when the magic happens. good video Dr Novak , now I can play around with the dollar store
Going to set up a new 100gal.+ tank................want to use your slow moving plenum, will be using sand for substrate cap. Do you think it is possible to use Father Fish's mud mixture over top of the gravel filter then a sand cap ? Haven't thought ofo the lift tube size. Link to the undergravel filter on amazon please. Thanks Almost forgot, Dr Raymond says Hello !!! He goes by Stephen the Biologist.
Interestingly I just received an email notification that the donation I made to the gofundme effort was being refunded. Any ideas as to why that might be? The organizer is 'K Lee Novak' which I assume is correct.
I am making a deep sand bed plenum in the sump of my reef tank. Interesting that nobody on TH-cam uses plenums with their dsb. Without the plenum it seems pointless since water doesnt penetrate 5 inches of sand lying on the glass.
I will never get another Apple snail/misery snail yes it was big and looked cool but it ate all my plants!! It was so big I watched it's mouth bite off pices of the plant. When it ran out of plants it attacked my fish
hi, can you make an anoxic filter using a hang on the back? There are some hang on the backs that allow you to adjust the flow, i was thinking if you just filled one with media (since water is usually clean near the water column) and reduced the flow it would make for an easy and cheap version of the anoxic filter.
So my BSB has been in the sump for 25 days now, something started happening around day 10 that I’m curious about. All of my clear hoses and I’m guessing the white PVC as well have cleared themselves of the brown build up they had. The clear hoses seem to have taken on a white appearance. The process was a little annoying for about a week as any adjustment to flow rate blurped out debris. That aside would this be related to the BCB basket?
The loss of algae would be because of the BCB and white on the hoses would be bacteria growing on them. My hoses do the same thing.In fact I have a video one just that subject too.

How are you going to prevent the substrate from entering the plenum from the sides. I agree with Annalee. Fluval stratum is a volcanic soil, not a baked clay. You can pulverize it between fingers easily. It will turn to mud over time. Also, it will drop your ph considerably. I have it in 2 of my tanks. It's great to grow plants but I think you will be disappointed with it as bottom layer.
Hi Dr. Novak, I got the Lee's original ugf for my 125 gal and the plates are not even and inch high there only 3/4 of an inch high. Im going to be using a reverse flow I was wondering if the ugf plates that you have are higher would be a better choice.Thank you for your time.
I have built a BCB into a Ehime 600 canister filter basically setup just like the one you did for the ADA. Once the BCB is fully established to current fish load in the tank how quickly can it adjust to the addition of more fish? Do you treat it just like a normal filter or does it adjust slower? Or faster? Just wondering what your experience with this is. Thanks for your help!
I ordered the same because the stuff that Dr. Novak suggests is 6 bucks each. These are way way cheaper. A little more water flow from these pics but i think if you put some coarse fabric sheet over the UGF you can adjust the flow. Did you get your yet?
This was a scam seller though. Price was a dollar plate but the seller took the money and then sent a message that the product was undeliverable. Hopefully i get my money back. How did your order go?
Hello Dr. Novak. I made the undergravel filter with the oxigen pump 3 days ago . I tested the water right after the installation and was: nitrates 5 ppm nitrites: 0 ppm ammonia: between 0.25 and 0.50 Today the water is: Nitrates 20 ppm Nitrites 0 ppm Ammonia between 0 and 0.25 How much time will take to this filter start to work with the nitrates? I will do a partial water change tomorrow. Do you have some advice to lower the nitrates without stressing the fish and the shrimps because water changes always stress them. Hope you can help me with this. Thank so much for your videos

@@jimlubeskie4312 No it doesn’t, the BCB is in the ADA but the water flows around it not through it. Look at the BCB as a giant magnet attracting the ions out of the water. Water goes into the BCB through diffusion.

Hello, Dr A word of caution if I may. The Fluval Statum you are planning on using will break down over time into very fine particles, and those particles will make their way through the grid for your plenum. I still have no trouble sourcing the baked clay. It is good to know, too, that the use of baked clay on top of a plenum is not necessary if one includes the use of a BCB elsewhere. I am currently setting up another aquarium with a plenum, and an Oase Biomaster Thermo 600 canister filter with BCB baskets. I will use the Special Kitty cat litter on top of the plenum. The last bag of it I purchased from Amazon was of the old type. Maybe, they switched vendors again, or I got lucky.
