substrate ferts for sandy bottoms

Hi all,

gonna be converting my planted discus tank from fine gravel to sand, as i think it looks better.

my question is.... can anyone recommend and non-layered fertiliser that wont ruin the look of the sand.

the reason i dont want to use something like laterite on a bottom layer, is that i live in rented accomodation, so may move reasonably soon. i may also be upgrading to a larger tank this year. the movement would mix any layered substrates and cause a mighty mess.

any thoughts?

I would just use some root tabs around the plants you want to fertilize.. that way when you move you can just sift them out!

I have a mix of peat / soil / Flourite / sand in 3 layers in my newly set up 90. I had the same thing in it before it was torn down. It is quite easy to seperate the sand from the flourite, and the soil/peat just washes away.

It is much easier to plant small plants in sand then flourite. I use root tabs under my root feeders as well on top of all this.

got CO2?

if i went with say 1/2" of flourite with 1 1/2 - 2" of sand on top... would this mix horribly after no time at all, or would they stay relatively layered due to the think layer of sand?

i know sand will sink down to fill the gaps etc, but will it force the flourite all the way to the surface?

If you vaccuum the substrate, plant, replant, or have any fish that like to explore what's underneath, the Flourite will come up to the surface eventually. If you want the beach look, I would go all sand, and add root tabs as Gareth suggested.
