hmm. Interesting hoppy! I simply sprinkled my clay into the tank so it slowly sunk into the substrate. Of course this tank is dirted already, but after about 2 weeks the clay began to give the ludwigia arcuata of which i sprinkled it around, an orange - red color tone to it. Of course this could be something else but i haven't changed a darn thing for months. Reason i added the clay is cause i did a little research (mostly on TPT) and people also had the same experience..

Also i must point out i'm not an expert to soils either. I merely test, and observe!

here is the thread i read, i focused on your post and the following post under you.
http://www.plantedtank.net/forums/11...-red-clay.html

p.s. (thought i might add) im not using pottery clay, i just got some red clay from the yard, dried it for a week in the greenhouse, and crushed it up to Very fine (under 1mm>) dust like sizes.

Hey Aaron, I will be using your guide for my first planted aquarium. The only question i have is would i be able to use pool filter sand instead of the black sand/gravel you used as a cap? I like the white look of the pool filter sand. i understand if it end up mixing with the soil it wont look so nice but was wondering what your thoughts would be?
Thanks,
Jordan Phelan

With a soil bottom layer, when you use pool filter sand as the top layer, you don't get mixing of the two materials. You do have to be careful when poking plants into the substrate, and if you make a mistake and pull the plant back up, you can get some soil on top of the sand, but it migrates back to below the sand over time.

First thank you very much for creating such a nice thread.. it took me on and off 3 days to go through most of the information.. user experiences and wonderful analysis..

Thank you Very much Aaron.

If my reply make any one angry kindly please accept my apology and dont want to dig a old thread intentionally. I saw a petco sale and wanted to try a 20gallon tank and to do a proper way.. went through many videos..and all decided to go Low tech.. first. Most of the videos says using Topsoil is old school and the plants roots digs deep into the top soil and its very hard to remove..and some just dumping any organic potting mix capping with some sand or gravel and adding water..

Saw another video using quikrete sand from home depot ..washing few times and adding to the tank. I want to do this proper and right way.. saw many replies ..many people trying different top soils.. every one posted the pics before trying and often forgot (i might have missed too.. sorry) to update their results if it worked or not.. i know its tough to expect everything and so nice of you guys spending your valuable time.

After all this years.. if any one have an ultimate formula..saying use this topsoil bought here.. use this clay..can be bought here.. use this dolomite.. it will really helpful and encourage more newcomers like me.. I live in Long Island , NY..and we have many nurseries around.. sadly most of them are whole sale..as a first step i will go around and ask about the topsoil that dont have any organic stuff or peat moss..and as much plain as it is..

can you please advise where i can buy lava rocks, dolomite (https://www.amazon.com/Dolomite-Lime.../dp/B0131MU8BO), Murate of potash and pottery clay in local stores..

Again thank you very much for such a in depth thread..and wonder why it kind of stopped in between..

Thanks.

The need for CO2 is caused by having a lot of light, not from using a soil substrate underlayer. When plants are growing slowly they don't need a lot of carbon to use to make new plant tissue. The faster they grow the more they need additional CO2 for the carbon. And, the biggest cause of fast plant growth is ample light. If you ignore this need for more carbon the plants will not be very healthy, and unhealthy plants invite algae to take over.

Hello! How to dose pottasium after initial source of pottasium is used? Can I dose the Muriate of potash that 100% water soluble? I read somewhere that we need to dose liguid dosage of Potassium (KH2PO4). What is the difference?

I'm finding hard to get red clay. Can I use gray clay which is available easily for me? Does that contain iron? Or can I use red soil (mix with little clay) that's commonly available in India? Is that one are you referring to laterite?

Thanks!

You can use Muriate of Potash. KH2PO4 has phosphate in it.
You can dose small of amounts of chelated iron, no need for red clay. I'm not sure if plants can access the iron oxide in red clay anyway. You can use clay laterite as well.

Hello there,

Will all plants do well with this method? Unlike the Walstad Method which describes that the soil as substrate (without Mineralizing), and some plants would not make it, and we focus the plants that grow well?

Thanks!
