I have a rather large 5' tank that I'd like to scrub up, has anyone here used Oxalic acid I watched this video a while ago and have being thinking about doing it but don't know where to get some

What do you guys think I have found Vinegar to not be so effective but maybe I'm not scrubbing hard enough

I did my used 450 L system with 90 litre vinegar and water, all equipment running for 3 days. Then with just tap water for 2 days. Then I took the pumps apart and gave them a rinse. Equipment, tank and sump..everything was done in one go with hardly any scrubbing
