The best cleaning method for used tanks

I have 37 used tanks and sumps and bioballs that I want to clean before we put saltwater in them. They are filled with water and running but just for leak test.

what is the best way to clean them?

Thanks,

I use a 3:1 water bleach ratio to clean anything used. Works great and always comes out looking brand new.

 

vinegar works well too, read up on it

 

I like the vinegar option if you still have the test water in the system. Bleach would be a little worrisome because you would have to get all the water out of the entire system and let it dry out after.

 

so how much vinegar would you use.
The tanks are not real dirty.

Should I just add some to the water and let it run for a day or two?
or remove all the water and srub with vinegar and water?

 

vinegar will make it look new again.. It will remove all traces of algae and coraline making stuff look new again..

 

You would have to also remove all the vinegar from what I understand as well. Are you able to stop the water from running for a few days?

 

I plan on removing all the water after the vinager treatment.
I just dont know how much vinegar to dump in?

how much water do you have? I use a 10 to 1 ratio and it works for me..

 

I have about 1700 gallons
