as i read this, skipping so very much of it.
the salesman from the LFS the OP was talking about, ...
ammonia released from decay, ... ya, this is true, unfortunately plants don't have a preference for ammonia, and thankfully there is beneficial bacteria that do, and they have a tendency to convert to nitrites, and the next stage in the (overly simplified cycle) is bacteria that convert nitrites to nitrates, ... and this the plants accept eagerly.
it's about the easiest source of nitrogen in our tanks for plants to consume
i don't remember for sure, but i think ammonium is the preferred choice for plants for a source of nitrogen, followed by nitrates. ... i could be wrong about the order, it's been awhile.

|Misti||ahh right the one I was originally at that recommended the Walstad style tanks that led me here. Back to Google. Thank you.|

ok I can see no help here
ok thanks for the link and Im no hijacker, others have asked their questions regarding this in the same posting as well.

Here are some filter-less tanks.
|08-01-2013 05:47 PM|
Im looking to run filter-less in my 2.5 gal tank here at work. There is plenty of light and I have a white fluorescent cfl bulb in the hood. Right now I have about an inch and a half of black sand and some water wisteria and a marimo ball. I have a Marble Gene Betta and 2 Dwarf African frogs. I know I would need other plants but not sure about the soil. I don't use potting soil at home. I use Peat moss with vermiculite and compost added. Really don't want to go buy a fancy soil from the store, but Im afraid of adding general potting soil to the tank whether it has fertilizers added or not. Any advise would be helpful.

Some dose GH booster once in awhile or Traces.
Not required, but can make the plants a bit nicer.
Fish load: I tend to suggest an overabundance of algae eaters which will also eat left over food. I use common sense here and experience.
I'd not add 6 Discus to a 40 Gallon tank, I'd maybe add 20 nice tetras or 10 rainbows etc. Then a bunch of shrimp, algae eaters etc.
You simply use common sense and error on the lower side and then progressively add more fish/food and see. Plants will tell you. Yellowing leaves on emergent pennywort for example, time to add more N.
Nice green color= things are doing well.
Gardening is common sense based really. Watch. Observe.
N can be anywhere from the single digits to 40 ppm etc without any issues.
Main thing is that they do not have large swings.
Most times, in non CO2 systems, they run low, not high, but if you over load the fish and under load the plants.......well.............
Common sense, set things up so you have to add more N, not remove it.
This way, folks can use plain sand etc, but a mix of both sediment and water column yields the best results IME. Which is also true for land plants.

CO2 can/comes from underground caves/springs etc, and we find the best nicest looking plant growth in such locations. CO2 is still there even if not enriched with a gas tank.......and is often limiting for denser plant beds in natural systems.

The only thing I've changed about Walstad's method is more frequent water changes. It's not flawed, it's just different.
I know it's an old thread but still.

|idleivey||Im running 5 NPT/Walstad tanks, most are under 5 gallons. I get great growth and have 1 tank with very prolific WCMs. If your really worried you could start with a small bowl I guess.|

my dirt tank
my first attempt ever
i dirted it with 1" dirt topped with gravel (because it said instant cycle and thats just not true, it really helped though, and it is good gravel for plants)
i did a water change a day for a week then added fish then did small water changes for another week or so and now i do one a week and top it up often. no co2 low lighting and i am in love with the results ! i do add root tabs now and im in month 4-5 i think.
|07-16-2013 05:35 PM|
just adding my thoughts since i too found a lot of resistance before going dirt, a thin layer is great about 1" no more, or even 3/4 capped with gravel, i used activ flora gravel just as an extra pop.
if you mineralize the soil first you do get over that initial bloom where the organic material is broken down, or if you just plant super heavily as i did the first time you get over it that way i never had any algae issues beyond the smallest amount, which the bristlenose loved.
mineralize the top soil by putting it on a tarp outside or in a greenhouse if you can, water it let it really dry then water it again, this activates the process of break down and improves the quality very significantly according to people who use this a lot, its my first time doing it this time for the 90g and i can see why it will make a lot of difference.
but i think you will LOVE the results with dirt, save a tonne of money and never look back ! i was able to run very low lights and extremely heavy planted tank with a lot of fish in there and everyone looks super happy and healthy, i waited a week before adding fish. lots of water changes if you dont mineralize the soil, because there will be excess nutrients and while the plants are settling in you need to get rid of that algae fodder ! but again i had never ever gotten a plant to live before going dirt, and i will never go back now !

You mean plants actually live in nature without Aquasoil and someone changing the CO2 tank once a month.
|01-12-2013 08:54 PM|
1 thing I have done, which was told is in her book, is have a siesta period (4hrs off)with my lights. This helps control algae for allows Co2 to build up.
Also you have to consider what plants you have. Some require a rich substrate. Also substrate peeters out in a year at the most.
It it works don't fix it.

I used to have a 29 gallon tank that got several hours of afternoon sunlight, plain gravel, old full spectrum lights, no filter and it was pretty. Clearest water I ever had. There's a pic of it in the Luscious Low Tech thread if you search my name. It was jungle-like because I liked it that way, but I suspect you could neaten one up easily enough.
Oops, I just saw the previous post about the age of this thread. Sorry too!
