...including old tanks and equipment with watermark. And pumps.
The simplest of all is white vinegar. You can get it economically at Costco. Some situations can be solved with a vinegar water solution, but when you've got a pricey piece of equipment that's been stopped or crudded up so it won't work, a gallon of vinegar straight is a cheap fix by comparison.
The other nice thing is --- even if a little gets trapped in your pump and sent into your tank, it's no big deal. Vinegar is benign so far as your reef is concerned, in tiny amounts, so no big sweat for washing it up---just a light tapwater rinse on newly processed equipment. If any straight vinegar hit your sump, it'd affect ph, but not catastrophically unless it was a LOT of vinegar.
Keep some on hand. If a pump stalls, just let it sit submerged in white vinegar for 24 hours. Might fix it. It also is great for getting the calcium deposit off your sink faucets and showers. Same stuff: it dissolves calcium carbonate.
