Can A Tank Be Fishless For Too Long?

I'm getting a used 20-gallon long tank tomorrow. I plan on taking things slow since this is my first tank and I don't really have the funds to get everything at once (decor/fish/etc). I've already purchased a filter with the capacity to cycle 130 GPH which I understand is enough for a 20-gallon tank. I'm going to pick up some gravel as well. From what I've read so far, its important to cycle the tank without fish for some time, but I'm wondering if its possible to have my tank without fish for too long?

 

Welcome to Fishlore!

There are a number of cycling methods out there that have fish in the tank and others where you need a source of ammonia. If you choose to go without fish, you still need to feed the bacteria until you have fish in the tank to do so.

Your filter, some would say is underwhelming. Ideally, with Hang on Back filters, the aI'm is ten times your tank size per hour. I feel safe at 7.5x as long as the stocking isn't maxed out.

We'd be very happy to help with any questions you would have for your tank. If you're unsure, about anything, just ask

 

Hi,
You can fill your tank, add gravel, wood, rocks and run your filter and only start the cycling process when your ready to do so.

 

So, I went back to the pet store and exchanged the 130 GPH filter for a 200 GPH filter. This should be better right?

 

Of course. There isn't a thing as too much filtration.

Life varmint said, just wait until your budget has or is close enough for livestock. Cycle your tank when you're close. No need to keep wasting ammonia for a long period.
