what is a good substrate to use im my brackish tank? i have a 10gal already going for about 3 months now and i finally got my 55gal anyways i was wondering if anybody could suggest a good sand to use

Crushed coral or aragonite sands are good, they all buffer the PH. I prefer sand personally, IMO crushed coral doesn't look to nice.

the crushed coral is what i am using now and its not pretty at all

I don't like crushed coral either (it grew a ton of algae for me, once I switched to argonite no more algae).
