Sorry, but I'm too lazy to redo what's already been done. Go read my journal (very detailed) here... http://www.apsa.co.za/Forum/index.php?topic=342.0
I stopped posting long ago, but my aquarium is still up and running with ZERO maintenance. I don't clean the filter, and I only top up the water when the levels drops (once in 6 months?) Oh yes, and the light tubes are almost 2 years old.

I also have 2 tanks outside with no heater, filter, or lights that I set up in exactly the same way. I have eleocharis parvula growing quite well in there - despite everyone saying that one needs light and co2 and a heater to do so. hahaha!!!

For those tanks, please go look here... http://www.apsa.co.za/Forum/index.php?topic=1719.0.

The secret with successfully doing an el natural tank is use natural soil, natural gravel, loads of plants and then DON'T MESS WITH IT!! Let it evolve naturally.

The proof is in the pudding. (my photos)
cheers!

Hi all,

How much soil (In kilos/kgs) would I need to cover 1.5" at the bottom with a tank dimension of 42"x18"x18" ?

I use about 1 gal of soil/sq. foot for a 1" layer of moist soil. I assume that your tank bottom is 42" X 18" or 3.5 ft X 1.5 ft. AND 3.5 ft X 1.5 ft = 5.3 square feet, which means you need about 5 gal of soil.

To convert to liters: 5.3 gal X 3.8 liters/gal = 20 liters soil

Soils will have a different weight depending on how moist they are or how much sand they contain. Therefore, I would base my final calculations on volume for measuring how much soil to use, not weight.

The easiest thing to do is just stick a 1 inch layer of moist soil on the tank bottom. Doesn't have to be exact.

Thanks Diana.You r a star as usual in your replies .
Its really difficult to find the cheap kind of potting soil with no fertilizers in my area.
Now,my question is......Can I use the soil that i dig from the forest floor near my house.I found its moist & rich in decayed leaves.Its Black in colour.I thought I'll mix some Laterite & sand in it & then use it.Any advice & suggestions are welcome.

Many thanks
