Aquarium Advice FINatic
I feel like this is great advice with a great thought behind it for beginners..your beneficial bacteria lives on the surfaces in your tank and isn't free floating in your water. That's why it's important to have a high surface area on your filter media or in live rock/sand.
Where I think this advice makes more sense to the beginners is that many think when they do a water change they are supposed to tear down the tank completely and wash EVERYthing and add new water. It's surprising to me how many people believe this and give it as a main reason why they don't want a tank bigger then a couple of gallons. If you do this then it makes complete sense to add BB back into the tank. But that's because it gets wiped out or takes a huge hit. After you start better WC habits and your tank fully cycles you shouldn't need to add anymore BB but if you are concerned about your fish you could use something like a stress coat.
Ok ! Some one that gets my intention, but how do you check if you have enough bb and how much has died off versus how much poop your fish produce? If you have alot of fish it helps break down the ammonia.
