Hey you guys so far I have a saltwater reef, a freshwater tank, and now I am finally ready to move onto a pond... well more likley a "fish tub" I am planning on using a 40 gallon "tub" that they sell at those home improvement stores. Now it has been a while since i set up my last tank, and I need a quick refresh on cylcing tanks. I would perfer the method that does not use any tester fish. do i just need to drop some of those nitrifying bacteria things that they sell at petco in there? sorry I forgot haha.
