The Cycle is the natural process in which the fish excrete wastes (fish poop and pee) into the pond water and Mother Nature has to deal with these wastes before these compounds pollute the water and make the fish sick.
The process is conducted by two major classes of bacteria. Nitrosomonas takes the Ammonia and breaks it down into Nitrite. Nitrite is broken down into Nitrate by Nitrobacteria. It’s not very complicated when you think about it.
A three step process with two bacteria who do the whole job. Now, these bacteria live in a film on the sides of your pond, on plant surfaces, and especially in the filter on the media inside. If you have a filter with a sponge in it, the beneficial bacteria which complete the cycle will live on the sponge. If you have a bead filter, these bacteria live as happily on the beads.
With filters, the whole focus is centered around getting beneficial bacteria to grow and live in your filter media. If your filter gets clogged with solid wastes, the bacteria are “choked out” and the filter becomes ineffective.
Filters should be cleaned outside the main pond in a bucket with pond water to avoid killing the beneficial bacteria with the chlorine which occurs in municipal water supplies.
SHORT AND SWEET: When you initially set up a new fish pond, there will be Ammonia and Nitrite accumulations which will threaten your fish unless you’re prepared. Bioseeding corrects that problem fast.

I have over ten of these Titanium Heaters in my fish room and at home. They're a paradigm shift in aquarium heating. They're titanium and 400W for under $30! Whaaaaaaaaat?
CyroPro by Hikari is safe and easy for Anchor Worms and Fish Lice.
Whatever heaters you use, back yourself up with a temperature controller, it'll turn on, and off your heaters. If your heater seizes "on" at least the thermostat will stop a tragedy.
LifeGuard by Tetra is a tablet version of a tame 'chloramine-t' or 'halamid' compound that's easy to get and good on bacterial infections, in baths.
For me, filtration-of-choice
Rubber sided, round, nettable tanks
1200 Watt heater, on a thermostat held securely above the waterline, works GREAT as a large tank heater. That's all I'll say because there's risk of electrocution and all that. But then, even in a bucket you could get killed. Sound like fun?
