So I have to clean a large amount of coralline-encrusted egg crate and powerheads. This will happen indoors. I'm looking for a safe and cost-effective option. I have a 20-gallon tote for this purpose.
Currently on hand vinegar (not cost effective for 20 gallons), muriatic acid (vapor issue?), and powdered citric acid (I know nothing about it, other than it wasn't cheap). I would like to make a solution that I can leave in the covered vat, and reuse when needed. Not sure if any of these acids will evaporate and become useless?
I believe a 1:100 ratio of muriatic acid to water is still 25x stronger than vinegar. That doesn't sound safe.
Which should I use? What is a safe, but effective dilution?
