Its okay i'm not offended, i really appreciate your advice, i would like to change to sand, but would not have a clue how to go about it and also if its safe as the tank hasnt been running for very long.

my partner picked that gravel out, it was his only input towards the tank.
I needed to add lots of plants in it to combat aggression as my swordtail was very bossy with the platys, and they seem happier having somewhere to hide and my mollies just love eating the plants.
They are a mixture of real and fake, the fake ones are mainly there so that when my pregnant molly drops her babys they will have somewhere to hide and wont be bothered much, if i just used live plants they would be bold in a week and serve no hiding purpose.
Finally i really want to add some bogwood but dont know where to get it in the UK, and how to make it safe to add to the tank
What I've been doing recently, with a view to designing a new tank (if my mum lets me get one...) is looking at the
Monthly competition winners - archive section of this site, to get ideas. There are some beautiful tanks there! Rgith, now prepare for a really long post:
Changing to sand: the key thing here is NOT to change it all at once. Lots of the benefcial bacteria, which help deal with ammonia and nitrite, live in the substrate. Therefore if yo uare changing substrate you need to do it bit by bit. A method I have heard of people from this board using is to make "dividers" out of plastic or acetate or something, not to divide the whole tank, but to split the substrateinto new and old so it doesn't get mixed up.so you'd divide off say 1/6 of the bottom area, take out the gravel, put the sand in. Then leave the gravel you have removed, inside the tank, contained in the foot of a stocking/pair of tights. This preserves the bacteria colony whilst the new substrate gathers bacteria. then after a while - i don't know how long hopefully someone will tell us - repeat this with the next section of the gravel. if your tank is genreally unstable, ie great flucutations of ammonia and nitrite, i don't think it would be a good plan. but if your tank is stable even though it hasn't been up for long, I don't think it would harm.
You can buy sand from your lfs but you could also use "play sand" from Argos which is much cheaper at only £2.49 for 15kg!!!

this might need a lot of washing, and some people say it clouds their water, but i think cheese_specialst used it in her tanks and it looks great. there's a link to them in her signature. other people have recommended pool filter sand but i have no idea what this is or where it's to be found.
It would be a lot of work though and you'd have to be really careful not to disturb the fish. also your live plants might object to being pulled up and replanted, i dunno, you can never tell with plants.

other things to know about sand are that if it is deep you can end up with anaerobic bacteria living in it, i can't remeber why they're bad but they definitely are, and to avoid it you need to swirl through the sand with a stick every now and then. this only applies if your sand is deep though, maybe 1.5" plus. if the intake of your filter is too near the sand it can suck in grain and totally screw up the impeller bit. to clean sand you can't stick a gravel vac straight in it cos it will suck up the sand; you need to draw the gravel vac along the sand a bit above the surface,so it slurps the stuff off the top of the sand without picking up the actual sand.
Bogwood: i get mine from my lfs. there's never any at pets at home though so you might need to look further afield. to prepare it for your tank, soak it in water or ideally boil it (if you have a spare saucepan!) until the water stops turning so brown. the brown stuff that bogwood releases is called tannin, it doesn't actually hurt your fish other than slightly lowering the pH which most fish don't mind, it's just that is makes your tank look like tea which a lot of people don't like.
aaaah I just realised how much I wrote, k, you don't have to read all of it, but it's there if you need to.
