Dr Tim's ammonia (ammonium chloride) is a quality product (it had better be for the price). He has a bottled bacteria product called One-and-Only
which will speed up the cycle quite a bit. Not cheap, but it really cuts down the cycle time.
He has instructions for using these products on his website. Fishless Cycling | DrTim's Aquatics
Alternatively, you can use the pure ammonium chloride, (ammonia is sort of the slang term) which does NOT foam when shaken, sold by Ace Hardware. Tetra Safestart, which is virtually the same product also developed by Dr Tim Hovanec, should be available at your LFS.
Tips while cycling is in progress:
---Turn filter on high
---Aerate with sponge filter or airstone or waterfall filter
