GH of flowerhorn tank and trace elements

[Ruturaj]

I am getting a flowerhorn tomorrow morning.

My GH of water is 3-4 degree which is very low for the fish. I have equilibrium and replenish but they don't seem cost effective. I am planning to switch to seachem cichlid lake salt.

1. What degree do I need to bring hardness to?
2. Do I need trace element from seachem as well?
3. Will I cause shock to the fish during water change? If yes, any idea to avoid. Add mixture of salt slowly while adding new water?

I would just use what you have. If you raise your GH, KH, PH you will have to match them when doing water changes which can be difficult.

My concern is lack of minerals affecting fish's health.

I don't personally use them, but I know products like CZ High Active and Koi Clay (Calcium Montmorillonite) are popular within the FH community.

I am going to go with seachem than other local brands. Same with food, nls or hikari, not flowerhorn specific food.
