    Proper mixture of muriatic acid to clean DE filter

    I have a Hayward Perflex EC65 - I've always done the soak with dishwasher detergent, but never have done an acid bath...

    My question is how to get the proper mix ratio muriatic acid/water.

    the EC65 manual states 1:1 ratio of 20% acid....

    my acid is 30% and the bucket filled with water is pretty close to the full 5 gallons - so how much acid should i add?

    and how long should i let them soak? (I currently have them soaking in TSP, gonna do that for 4 hours)
