Waay too lot! I my opinion is to do a fish in cycle. Risky, but never lost fish to it.We've got a LOT of opinions around here!
Mine is find another established tank to grab some filtration media or substrate out of.
Short of that I've got to leave the bottled starter products to those in the know. I've never used them.
If you have zero access to that, then you've got to start from scratch.filtration media or substrate don't have any have to cycle some other way
Try your local fish shop. They may be willing to give you a small handful of gravel to add to your tank. It actually doesn't take much to get the colonies started. If you don't want this gravel to mix with your current gravel or sand, you can put it in something like a loose woven nylon bag, a cheese cloth bag, or the end of a nylon stocking with the opening tied off.filtration media or substrate don't have any have to cycle some other way
My 55 gal starting leaking after 20 years so I got a 75 gal . Never had to cycle a tankIf you have zero access to that, then you've got to start from scratch.
I encourage you to read up on fishless cycling if you already haven't. There's other methods that you can make work as well. Either take a lot of dedication and patience.
What size tank? What do you intend to keep?
I recommend tetra safe start along with established media and substrate or at least a mix of new and established substrate then start off with small bio load and add whatever fish slowlyWhich one of these would be best to cycle a new tank? Fritz Bacteria Turbo Start or Dr. Tim's Aquatics One and Only? Would really appreciate any insight.
