Its a 135 gallon and i was wondering what would be the best way to cycle it without fish? i would like it ready for use in 2 weeks if thats possible.

P.S. I dont have a filter for it yet..Do i need a filter to start cycling it?

Yes you need a filter probably 2. The quickest way is to use media from an existing cycled and healthy tank.

Yes you absolutely need a filter!
My 135 works great with a Rena xp3 and an ac110.
I do water changes every 5-6 days and nevber have a problem.
Fishless cycle with ammonia will work but may take longer.
If you have a cycled tank that you can atake media from use it.Stock the tank slowly with proper water changes and it should be fine.

Will sand and driftwood from my old tank be enough? Im going to use the filter from it as well seeing as i need one.

How big is your other tank? If your filter is big enough for the 135 gallon tank, I would imagine you would have an instant cycle. But then your other tank might get a spike.

Moving sand and driftwood and the filter media from the old tank will make a huge difference. So will moving some plants. To further jump start it you can put water from the old one into the new when you do water changes.

I recently set up a new (used) 40 gallon tank. I put new gravel in and used filter media from an established tank to seed the new setup. I also moved a fair amount of Najas from a couple other tanks and some Endler's into the new setup to get it established. I may be moving a few pieces of driftwood and some sand from a couple other tanks as well, depending on how well/quickly the new one becomes established.
