Props for reading the article and doing the more humane fishless cycle.
The shrimp, ph and a heater are all you really need.
The cycle should go like this:
Rise in Ammonia, nitrItes start to rise and ammonia declines, the nitrItes will spike and nitrAtes will start to rise, once the nitrItes are at 0, do a decent sized PWC
(to remove the nitrAtes) of about 20-30%. Then you can add fish, but only one or two at a time, to give your tank a chance to catch up to the new bioload.
