How to clean an old or previously used aquarium with hard water stains, or calcium deposits

  1. Fanatic
    Okay, did you find an old aquarium for sale, but it turned out to be really filthy once you received it?
    Believe it or not, there are actually methods to make it look brand new, and it's really easy to do.
    If your tank has any mineral buildup or hard water stains, then this is a guide for you.
    I have included some of my go-to methods, as well as great recommendations from people I have spoken with in the past.

    Cleaning Agents
    There are many ways to do this, both organically and chemically, so please choose what sounds best and works for you.
    I have confirmed that all of the given methods are safe, and will not hurt your tank or fish in the future.

    • Pure Ammonia
    • Bleach
    • CLR (Calcium Lime Rust)
    • Fresh Lemons
    • Razor Blade

    WARNING: DO NOT MIX AMMONIA WITH BLEACH

    Reminder!
    Be sure to thoroughly observe your tank for cracks or damage, and do a proper leak test beforehand, then you can confirm that your tank is safe and can hold water.
    It's better to do this now than find out the hard way later on.

    Attention!
    If you are going to use rags or scrubbers to clean the tank, be sure not to scrub at the hard water stains, it can pose the risk of scratching your tank or worsening any preexisting ones.
    Instead, use the blade to remove the deposits, then scrub the glass until clear.

    Step 1
    First, get your tank into position, preferably outside away from the house as not to get the chemical smells into your living area.
    That poses a risk to other pets and animals.
    You can then prepare your cleaning agents to work on the tank.

    Step 2
    Next, once you have the tank and the chemicals outside, you can then get the razor blade onto the glass, and carefully scrape away at the stains until removed.
    You should wet the blade for ease of movement and removal, you can use the chosen chemical for this.

    Step 3
    If you aren't using lemons for cleaning, then please skip this step.
    You want to cut the lemon directly in half, then rub and squeeze it onto the stains with your best efforts, as long as you want until the removal has improved.
    I like this method, because it's easy, and smells great!
    This method may not be as effective as the abrasive chemicals, but it sure works well in a pinch.

    Step 4
    After you have removed the stains, you can then rinse your tank very well before bringing it inside.
    I recommend a hose for doing this, the water does not have to be treated.
    Be sure to remove all of the chemicals, it will be safe once rinsed.

    Okay, that's it for this guide, hope it helped, and if it didn't then please tell me why, and where it needs improvement.
    I have seen a lot of dirty aquariums and thinking that it needed a solution, this guide came to my mind.
    If you need help, don't be shy to ask me or anyone that knows about this topic.
