but when i test the water before i put it in the tank the KH is normal, like 12 dKH ??? my fish are ok(except the picasso he died this morn for unknown reasons
) i guess i could use RO from the lfs or buy a unit i just never used it before and all my water changes are successful(except my first i lost practically everything)

If your tap is at 12, adding salt that probably has an alkalinity buffer in it (most salts do) is only going to make it even higher which is why I'm saying to STOP using tap water.

oh ok cuz i didnt understand oh and i forgot i do dose the water that i top the water off with i use marine buffer cuz the pH is low i also add it to the water that i do water changes with is the water. are the parameters in th RO water tank ready or does it have to be treated??
It depends on the quality of the RO that you're using, but it's going to be damn better than your tap.
If you have really high alkalinity and low pH, there is a major issue going on. Start using RO water for water changes and top off from now on. I'd do a major water change using RO to try to get the pH and the Alkalinity better under control.
What salt are you using?

This is what it sounds like you are doing wrong. Fresh water has a pH of 7 and there is no need to adjust it before adding it to the tank when topping off or doing water changes. So you should only be testing the tank water there is no need to test the top-off or the new saltwater. By dosing the top-off and new saltwater you are over dosing the tank.
Now if the tank had a low Alk then adding it to the top-off would be the way to go.

Just to reiterate - PH Buffers raise Alkalinity, that is the only thing they do - they do NOT fix a low PH long term.

pH-8.2
Specific Gravity-1.024
Temperature-76 degrees fahreinheit
i dont test for calcium or alkalinity, so i guess i shud b
KH or dKH is alkalinity (carbonate hardness).
You should not be dosing an alkalinity buffer or pH buffer without also knowing your Ca level.
