Do you have a liquid test kit to monitor ammonia/nitrite/nitrate while you cycle? Don't waste money on test strips - the results aren't accurate. You'll want to pick up something like API Master test kit and test daily while cycling. Check out the sticky posts for more info. Make sure ammonia stays below 0.25 through frequent (possibly daily) water changes and sparse (every 2-3 days) feeding until your filter builds up the ability to turn waste (ammonia) into nitrAte, which is less toxic and can be removed with less frequent water changes. If your local store doesn't carry a good liquid testing kit, Amazon sells the API kit at a reasonable price.
Also use a good quality dechlorinator. Most prefer Seachem's Prime. It's highly concentrated, and will temporarily also neutralize ammonia.
