You will be in the range for what you want to do, especially for the tank size you intend to work with.
    Thanks mate. I will definitely be checking my mix with proper titration soon. I will create a simple non technical step-by-step tutorial and post to contribute back to the wonderful help I'm getting here!

    Also, got me some lovely lovely platinum coated titanium strips to hand the parts. Pics soon

      Hi everyone, again. I had to pause this project, but I'm back to it.
      Reading up ob the Caswell manual once over, I'm again plagued with some doubts.

      So I've seen loads of videos on DIY / hobyy anodising, and I've never seen anyone do this de-ox step.

      On page 8 where the whole process is topic'ed out real quick, item 3 says;

      3. Anodizing De-Oxidizer Dip the part for 1-3 minutes into the pre-mixed solution at 100 deg F. See the section on Aluminum De-oxidizer

      Well, there is no such dedicated section I believe.

      But it got me wondering, this step is essencial correct? … if aluminium does "seal" or "cure" by itself in contact to open air, one must always de-oxidise the part before anodising?

        Aluminum does not seal itself in open air. It will grow a very thin layer of oxide in open air, and that is what you are trying to remove by etching and deoxing.
        Process control doesn't give you good quality, it gives you consistent quality.
        Good quality comes from consistently doing the right things.

          Ok, got it. But since I'm going to be brushing heavily before anodising, and since I'm not looking for a mate finish right now, I can skip etch/deox, right?
