I decided after reading a thread by Tom Barr to create my next tank using a soil substrate. The reason that i decided to go down this route was solely on the basis of saving money, time will tell how effective it will be.
From reading on this forum i've noticed that quite a lot of people have started thinking of using this method of substrate and have often asked of the best way to go about it. So i thought i'd show you share my current experience with a soil substrate.

First off i dug up a wheelbarrow full of garden soil and the sieved it to remove any rocks, stones or roots. I then transferred the sieved soil to a large plastic container and covered it with plenty of water.

I left this container for around five weeks, every few days i'd remove any floating debris, gave the soil a stir round and changed the water. Until now when it was ready to go into my tank.

Today, I removed as much of the water from the container as i could with out tipping the soil down the drain with it. Then comes the messy bit of mixing it with the gravel and/or sand.

This is what i used -


I would have used just plan 2-3mm sand/gravel but my friend had a load of play sand which he gave me, i thought this on its own would be too fine for the plant roots so i decided to add some fine gravel which ranged in size from 2-8mm.

I then cleaned the gravel and sand and mixed it with the soil.
For my tank which measures 38" x 23" I used 3 1/2 bucket loads of the mix giving a thickness of a good 2 inches, I may take some out when it come to adding the top layer of sand.

For the mix i used a ratio of 2 parts soil, 2 parts gravel and 1 part play sand.

This is how the soil substrate looks like in the tank -


There aren't really any tips i can give you on preparing it only to try and get as much water out of the container before mixing, it may sound obvious, it would make it a lot less messy. Also its probably not the best thing to do whilst your mum or wife is in the house they're not big fans of people carrying buckets of mud through the house.

So far its looking good took around 1hr to do, plus 5wks soaking and cost me £2.90 for a 25kg bag of gravel.

Regards.
 
Good to see someone trying this out, well done.

I wonder if a layer of gravel might be better as the top layer, no reason to say that other than gut instinct, I wonder would the sand compact over time.

When are you going to plant up the tank? let us know how you get on.
 
I know what you mean, i want to use sand to give a nice top layer, though you are right about it compacting i think i might put a top layer of gravel where planting and use the sand in the open ground.

Just as i was righting this some of my plants arrived from AE,

Plants from AE - Cryptocoryne balansae, Crypt wendtii 'brown' and 'Tropica'

Other plants, Echinodorus uruguiensis, E. amazonia, Bolbitis, C. lucens C. albida C. undulatus 'red' and some mosses.

I'll post some pick when i plant the tank up you can se it here

Going to spend the day in lovely coventry today though.

Oooh, Coventry! Where abouts? Guess which "lovely" city I live in :D

Liking the soil idea at the moment. I have a little 24x12x12 tank which I'm telling my self I should sell.... ...... ........

Hope you have had all your innoculations.

I always think that a healthy root system would keep the substrate healthy. Sandy foregrounds always look nice in my opinion.

Looking forward to the pics, Afro.

Sorry about that i went to see my brothers final piece for his degree, first time i went down to see him, he never seemed to like coventry. I thought it looked quite nice though, maybe that just what the nice weather does. :shifty:

I should finish the set up today so i'll post some more pics.
 
Looking forward to the pictures...
 
I've finally got round to finishing the substrate, fromt the last picture i removed quite a lot of the soil mix, approx 1 1/2 buckets to give the shape of the planted areas, it can get a bit messy.


After this i placed a layer of fine gravel to a depth of about a inch onto the soil mix.


I then filled in the forground and the path with the playsand.


All i have to do now is cover a load of driftwood with moss and plants the plants.
