I started a fishless cycle on my 75 gallon about a week ago with the method of keeping it at 4-5 ppm rather than adding so many drops per gallon per day. I had read many other places that too much ammonia can kill or slow the growth of the bb, not sure if that's true reading this post now. I still only have ammonia, no nitrites yet. I didnt have an established filter or media to put into this tank but I have two bio wheels going. I had a bacteria bloom a few days ago because the water got pretty cloudy but it has cleared up now. My tanks temp is at 82. I'm wondering if I should start adding ammonia everyday now or if both methods take about the same amount of time to cycle the tank?

I used that method (keeping NH3 at 5ppm) to cycle my 36 gallon, and it worked fine. I think the other method overcomplicates things.

This should be stickied. It's succinct, to the point, and easy to understand. I wish I had done this with my tank and I wouldn't be having the problems I am.

Fishless cycling...

It has come to my attention, that there several times that I have had to explain "Fishless Cycling".

Every new tank, with new filtration, has to be cycled to be safe for aquatic life. What is meant by "cycled"?
"Cycled" is a reference to the Nitrogen cycle. This is the bio filtration that happens in our filters.
In short,
"Ammonia" (toxic fish waste) is converted by bacteria into
"Nitrite" (toxic as well) then converted by a second type of bacteria into
"Nitrate"(basicaly harmless in low concentrations) that gasses off in the Aquarium.

This read is not for the advanced water chemist, this read is directed to
those fishkeepers that do not know what the nitrogen cycle is, and have had problems with keeping fish alive and well in their new tanks and with new filtration...

OK to start off there are a few things that you are going to have to have PERIOD...
1)Water test kit (Ammonia,Nitrite,Nitrate)
2)patience
3)Commitment to cycle the tank completely
4)Pure household Ammonia (clear w/no soaps or fragrance)
a)shake bottle- if there are bubbles - no good
if it looks like water - way good
5)Aquarium needing cycling with the water set to 85 degrees F.
6)Filtration, installed and working properly.

First thing, first...
Bacteria thrives in water over 80 degrees F.
Make sure to set the temp to 85 degrees F.

Next you need to know how much water you have. Use the conversion chart here http://www.monsterfishkeepers.com/forums/calc.php

Once you determine how much water you have in the system, de-chlorinated the water with a de-chlorinator that does not contain anything that says "eliminates ammonia etc." I use stresscoat and I know that works.

Now, you'll add 5 DROPS of Ammonia per 10 gallons, no more no less. Pick a time of day that you'll be able to take readings, everyday, for a couple of weeks.

Do this everyday until you see a measurable amount of Nitrites.
When you have a Nitrite reading, this means you have started the nitrogen cycle and are effectively growing the Beneficial Bacteria, that converts the Ammonia into Nitrite. We are half way there.

Now you will lower the amount of Ammonia to 3 drops per 10 gallons per day. You will do this until you get a reading of
0 Ammonia and 0 Nitrites. ZERO means ZERO, no matter how long it takes to get there. You are now building the Bacteria that converts the Nitrite into Nitrate.

Ok, so now we are adding 3 drops per 10 gallons of water daily.
We are getting a reading of Zero Ammonia / Zero Nitrite and we have a Nitrate reading of 20-40 ppm. You are almost there.

You need to do a 50% waterchange with de-chlorinated water and adjust your temperature. Now is the time to get your fish. Acclimate them and get them in your properly cycled tank...enjoy them as they will be enjoying your correct water parameters...

I hope this gets you on the right track right off...If you have any questions PM me, I'll be glad to help out...
Zen,
Can you use Seachems Prime as main De-Chlor while using this fishless cycle???

Man. I wish I would have read his a few weeks ago. I was told by the guys at the fish store to cycle it with some cheap fish... now I feel bad for making them go through that...
