Hi Sean
Don't dispair... It's not easy when you're new to the hobby and the LFSs can lead you astray. Hake heart that you have done the right thing and come to the right place. Follow the advice of the people here, and it will be fine. Its difficulty to show patience even as an adult during the cycle, IO can't imagine what its like having a nagging little one around who ca't wait to see fish...
As it happens, I documented my test results each day during the cycle. I cycled the tank using raw shrimp because we can't get the high-grade ammonia here in Australia. Have a brief look because it will give you an idea of what to expect.
You can imagine the look on the shop assistance face when I went and asked for 2 raw shrimp. (I'm allergic to shellfish so it was pointless buying more). They ended up giving them to me for free.
Fishless Cycling Test Results
At the end of 3 1/2 - 4 weeks, the raw shrimp has pretty much disintegrated into nothing and in my case, I needed to add more for the last week. Its not very hard to get out of the tank. I used a rubber glove (purchased new and never been used for cleaning) and just scooped it up and threw the remainder away and at the same time (within the hour) stocked my tank. Although, I can see how the stocking idea has merit.
And don't do ANY water changes until your fishless cycle has finished, regardless of whether you use shrimp or ammonia. You want to iniitally get the ammonia level up to around 4ppm. For a 2ft tank, I used two and a half whole raw shrimps and that have me 4ppm exactly. You can use that as your rough guide.
Keep us updated, and welcome to AA!
