Forgive me if I rant about unfounded manufacturers claims for a moment. This is in no way intended as a criticism of your post.
My goodness, now theyre claiming to sell water with bacteria already in it? I thought the unfounded claims about "live sand" (thats been in a bag on the shelf for months) and "rock with bacteria embedded in them" (LOL) would have burst this bubble, but now they're actually selling water they claim has bacteria in it?
Undoubtedly all these products have "some" bacteria in them, just like the doorknob and the toilet seat do. Doesnt mean they have *any* of the useful ones, let alone *enough* of them.
Consider this:
- The water on a healthy coral reef in nature has at least several hundred different kinds of bacteria, as measured by DNA sequencing.
- The water in an established reef tank also has several hundred different kinds of bacteria.
- >99% of marine bacteria cannot be cultured.
- Bottled products I've tested contain about 0-10 different types of bacteria, and I've found no evidence yet that any of these survive once placed in the aquarium.
Given these info, I hope the reader may understand my frustration with unfounded manufacturers claims about products like artificial rock "seeded with bacteria" or (this was a new one to me, which prompted this rant) water that "already contains the necessary bacteria".
Would we purchase a calcium supplement when the ingredients don't list calcium and the manufacturer provides no evidence it contains calcium? So why does the hobby spend millions upon millions of dollars on products that offer the same level of evidence?

With that rant out of my system, I would suggest this for cycling your tank.
Ignore all manufacturer claims without evidence. Get some live rock or live sand that came from the ocean or an established tank. Put it in your tank and wait 2 weeks, and if it was real live rock or sand in the first place your tank will be cycled.
If youd like to confirm that its cycled I suggest you dose ammonia to 1-2 ppm and measure how long it takes to drop back to zero (make sure to keep the lights off during this test to avoid algal growth and algal uptake of ammonia).
Good luck
