Obviously you haven't read the links that mommyof2bettas gave you or you wouldn't be asking is there anything else i need to put in the water or just leave it for a few more days for the filter to mature? your filter wont mature unless you give it something to mature with! And it will take a couple of weeks, not a couple of days! Read the threads that were suggested, they will answer most of your questions, then if you're still unsure about anything ask. If you're not willing to take the time to read the material supplied and take the advice you're given, that's fine, add fish to your tank and watch them slowly and painfully die but don't expect too much sympathy when things start to go pear shaped on you.
the ph in my tank is 7 and has been over last couple of days
Ph levels are the least of your worries as most fish will adapt to whatever your tank's ph is, changing it is difficult and is very stressful on the fish, so leave it alone and buy fish to suit your water.
im going to put 2 in when its ready to see how they go
Get yourself a liquid test kit, once you've read the threads on cycling you'll know when you're able to add fish!
You also don't say how big your tank is, no one can give you any stocking advice until we know that.
