Magnesium Sulfate upper limit

[Bill]

I have a 120g heavily planted tank with discus in it.

A couple of the discus are bloated and they need to be treated with Magnesium Sulfate.
The treatment is 1-2 teaspoons for every 10 gal of water.

My question is can I treat them with this much Magnesium Sulfate in the tank or will it harm my plants at such a high dose?

Thanks,
Bill

Re: Magnesium Sulfate upper limit

1 tsp per 10g will add around 14mg/l to your tank. 2tsp per 10g will add around 28mg/l.

The lower level shouldn't be too much of a problem. Not sure about the higher level but I don't think it'll harm. Maybe someone can give another opinion?

It will raise your GH by 4 to 8 degrees (if I remember the calculation correctly!).

First I've heard of using MgSO4 to treat fish.
