Re: [AGA Member] Aquarium Planning

"My plan is to cycle the tank with fast growing plants only, no fish."

Cycling refers to the period of time when the bacteria which convert ammonia 
to nitrite & nitrite to nitrate colonize the tank. See 
http://faq.thekrib.com/begin-cycling.html for a very nice explanation of the 
nitrogen cycle.

Since plants are nitrogen consumers, not producers, you cannot cycle a tank 
using plants only, unless you were planning to add ammonia as a nitrogen 
source in the tank. But, since plants us ammonia and ammonium directly, even 
if you did that you might not see the NH3-N02-NO3 progression that you would 
see in a non-planted tank.

The only reason I can think of for waiting more than a day or two to make 
sure heaters, filters, and lights are all working before adding fish is if 
you want to wait a week or so to make sure the plants are really going to 

My own preference, if you want to be serious about plants, would be to go 
with a substrate meant for plants, like flourite or caribsea eco-complete, 
rather than messing with the laterite mixture.

Sorry if this is stuff you already knew.
