Hello

U can go for chloride process i.e Acid Zinc and on it u can do Black Triv pass. It gives very good results. All u 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 sulfate 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.
