Becareful with the soil from garden centre. Don't think all of them suited for aquarium use where there is shrimp and sensitive fish in it. Some potted soil had fertiliser added to it with loads of copper component. Look through the nutrient component before purchasing it. Regular top soil or potting mix should be fine if there is no fertiliser in it. Obviously if you are setting a massive heavily planted tank with minimal sensitive livestock in it, this should minimized the risk as plants are quite effective in removing heavy metals from the water column providing they are thriving.

Best bet from a garden centre would be a John Innes Seed or Cuttings Mixture. Make sure that it has low NPK values and no slow release fertiliser added to it.

Or just use some of your garden soil! As long as you haven't added lots of fertiliser to it or put any herbi- / pesticides on it.

I think it was a loam based John Innes mix, so it didn't just dump all its nutrients all at once like a peat based one would (think Ive got that right!).

Anyways... updates: Changed a couple of bits around such as the Dwarf Sag, added some Java fern, added a couple more rocks (don't like them really, they're too bright!) Hope you like

It's about 5", and almost root-bound at the back :wideyed:
If it were only 3" deep do you think your plants would grow just as well?

I'm wondering if the answer is yes for EI or similar dosing and no for El Naturel like you are doing here?
