@Tissue Tenant
Can you please post exactly what sort of fish food you were using to make ammonia?

Since you said you had so many tanks I figured the big jug was better for you. But you can use the Fuel I suggested for TT to try a single fishless cycle to satisfy your curiosity. It is for one or two tanks cycling. I have the big jug ammonium chloride because it is more cost efficient for me. I used to use Dr. Tim's but I now duplicate it myself using the Fritz dry. So the Fritz Fishless Fuel would be fine for you as well.
You both can also get Dr. Tims One and Only
One and Only 2 oz free shipping $16.99.
If you want to see how I cycle in the biofarm and have not seen this thread,

Next, most of the ammonia from fish comes from the fish exhaling not from their poop or urine.
Ammonia is formed from the metabolism of protein and is the major waste product of fish. The majority of ammonia from fish is excreted through the gills, with relatively little being lost through urine and feces. Ammonia is also formed as uneaten feed or other organic matter in an aquarium decomposes.

Ammonia in Aquatic Systems

Introduction
All animals excrete waste in the process of metabolizing food into the energy, nutrients, and proteins they use for survival and growth. In fish, this primary metabolic waste product is ammonia.
In fish, the majority of ammonia is eliminated from the body primarily by diffusion through the fish’s gills into the water. Smaller amounts are excreted in the urine or across other tissues.

And here is the real kicker in this. The above facts about how fish excrete ammonia has been know for close to 100 years.
THE EXCRETION OF AMMONIA AND UREA BY THE
GILLS OF FISH.
BY HOMER W. SMITH.
(From the Department of Physiology, University and Bellevue Hospital
Medical College, New York.)
(Received for publication, January 23, 1929.)
A very small total nitrogen excretion by way of the urine ap-
pears to be typical of fish. This statement is attested by the
analysis of Lophius urine reported by Denis (l), Marshall and
Grafflin (2), and Grollman (3) and by the analysis of the urines of
Mediterranean fish reported by Edwards and Condorelli (4).
Further evidence is presented in Table I, in analyses of urines
removed or collected by catheter from fresh and salt water fish,
both fasted and in the active process of digestion. .............
We were led by the above and other facts to suspect that nitro-
gen, possibly as ammonia or urea, was being lost from the body
by some route other than the kidneys, and the gills appeared to
offer the most probable avenue for this escape.
