Hello

You can go for chloride process i.e Acid Zinc and on it you can do Black Triv pass. It gives very good results. All you have to do is that it requires some extra care.

Hope it will help!

Well, that's like asking is red or green "better." It's a matter of personal preference and experience. I use a chloride based trivalent chrome and we experience very few problems as long as we keep parts out of the bottom of the tank and we control our temperature closely. I have never used sulphate based trivalent chrome but I am sure there are relative advantages to each. In a situation like this, ask your current proprietary chemical supplier about the relative advantages of each, make some plant visits and make your determination from there.
