Best Way to Clean Old Tanks

So I have several tanks that have been used in a greenhouse to keep pond plants over winter. They currently have some real tough hard water stains on them as well as dead algae on them too. I tried using soap/water and a sponge but to no avail. Whats the best way to get them nice and clear again?

are you a sink or source?

I have used vinegar to clear up those hard water stains and it works well.

Vinegar is your friend! Use a gallon. No really, it comes in gallon jugs. Dump the whole thing in there, fill the tank to the top, and let it sit overnight. You'll be able to wipe off the hard water stains and anything else that was in there with nothing more than a paper towel.

Vinegar is good! I use it to clean all the time My issue is these are medium size tanks (30 and 55), and that would be a lot of vinegar. So I was thinking of a stronger acid that might disassociate completely in water, and of a high molar concentration, that way i could just pour some down the sides (of course there would be water in the bottom cause you never add water to acids, you add acids to water).

What?

ETA: This is exactly what I did to clean out my 55: Get the hose running into the tank. Dump in the gallon of vinegar. Fill up the tank the rest of the way with water. Let it sit overnight. Wipe it all down with paper towels. Siphon out the vinegar water. Use tank. Total out of pocket for vinegar was $2.

What to what part? Never water to acid because the acid would splash. Basically I just think zherico wanted to use a stronger acid that would clean the stains quicker as opposed to soaking it over time.

I use vinegar and baking soda to clean out gunked up filter tubing. Works like a charm. Pour some soda in, shake it around to distribute, cap one end, pour vinegar in and cap the other end. Make sure you keep it contained and rinse afterwards. Nice clean pipes.

I used vinegar to get rid of hard water stains that had been on the tank for ten years, worked pretty good.

I use vinegar and a razor blade (glass tanks only, not acrylic). I don't soak the tank, I use a 50/50 vinegar/water mix in a spray bottle.

The lazy gal way: soak some paper towels with vinegar. Lay them on the bottom or side, whatever's down. Wait 10-15 min. Turn tank over; repeat. Works like a charm. This works great on glass tops that are cakey, too. Minimal effort. Just rinse it off.

I use CLR then wash with soap and water. Easy peasy.
