How much discus buffer for 28 gal with hard water?

I agree it is a small tank for discus! I'm getting my 55 from home come xmas, i had a friend who all of the sudden got out of the hobby and needed a home for the fish =)

Back to the discus buffer! I'm asking bc I have a sick one who was always the dominant until now. The other two were pretty stunted as juvies and so are small but they are still doing fine. I tested my water, the readings were good and can be seen in one of my previous threads but the water was hard.
The tap water I use is usually soft but I think they may have added something to it for the time of year or something.
I got discus buffer bc it says on the bottle it also makes water soft. The friend I got it from swears by it but I didn't buy it at the time because I too usually stay away from chemicals like that as I find they usually aren't necessary/effective.

Any ideas??
 
If your tap water is normally soft it should still be that way. Deliberately increasing hardness is not a common action by a water company but it may be picking up something from within the plumbing and water mains.

Rather than guess, or think, testing your water is best before taking any action. It's the only way you're going to know for sure where your water lies in hardness value. You will then be able to add the correct amount of buffering. If the tank is planted, that is a big plus even though it's not a cure and in some system has no effect whatever.
 
just age your water and add some amquel. i use to use this stuff all the time, but you dont have too.
