Cycling Question

Question
Hi,

I have recently tore down my 20 gallon aquarium due to new tank syndrome.  In the old tank, I tried to cycle with two guppies.  I have just redone the new tank setup and plan to fishless cycle with cocktail shrimp.

In my new tank setup I have two powerfilters (one Penguin bio-wheel and one Aquatech (with a sponge)), a power-head, air pump, airstone x 1, heater.

My questions for you are:

1) Can you provide any information for using cocktail shrimp to fishless cycle?  I have found some information, but would like to read more.
2) What temperature should I set the heater to for cycling purposes?
3) Do I need anymore equipment for this setup?

Thank you,

Jeff

Answer
Good afternoon Jeff,

Thanks for writing. The only thing I recommend is that along with sponges, you also use the Biomax rings for your AquaClear filter. These should be rinsed weekly in dechlorinated water, there is no need to dispose of these or replace them ever, unless they become damaged.

To answer your questions:
1) All you need to do is put a small piece of cocktail shrimp (say 1/2 a piece) in the tank. In about a week, it will degrade. That's when you should test your water with a test kit. If ammonia or nitrites show up, your tank still isn't cycled - add another piece of shrimp if it's gone (it will turn into a grey goo) and wait another while. Your tank is cycled when it shows 0 ppm of ammonia and nitrites and trace amounts of nitrates. If you don't have shrimp, you can use flakes - "feed" your empty tank a couple flakes daily.

2) The tank cycles best and fastest at a temperature of between 84-86 degrees. Most heaters can only heat up about 20 or so degrees max above ambient temperature, so if your house is very chilly your heater may not be able to attain these temperatures, but likely it can. Do remember to bring the temperature back down before adding the fish!!

3) I don't believe you need any more equipment, but a water test kit, an aquarium book such as "The Simple Guide to Freshwater Aquariums" by David Boruchowitz are essentials!

I hope that helps. Do check out http://freshaquarium.about.com for more info, especially the section to the left called Aquarium Startup. Take care!
