 If I want to use citric acid, in what concentration should I mix it?

 

20% is enough for most common uses

Actually when someone doesn't use an avatar the forum has a placeholder for that. Here there is a broken link on the image so it's a misconfiguration. If admin doesn't care I don't care either

I'm not sure what are water marks. Do you mean water limestone residuals?

 

In that case I would just use vinegar or, even better, citric acid (one small bag used of coffee machine cleaning). Just soak for few minutes your dome in a water diluited soultion.

If you use  Novus, N. 2 should be enough.

I used the NOVUS 3 and 2 on my Nauticam acrylic ports several times now.

You won't be able to remove huge scratches with it. Consider to start directly with 3 and then 2. Repeat the procedure four or five times. Wash with water between each step to remove Novus and to check how it is going on. 

Even if you do not remove completely the scratches they will be invisible underwater.
