I am about to add fish to this tank finally. its been cycling and has new ada amazonia in it so i have been dealing with ammonia for a few weeks.

i just want to make sure i have the proper electrolytes, calcium and magnesium in my water for cardinals and rcs. my gh and kh just measured to about 2 degrees so thats about 35ppm. is this too low of a value for the health of cardinals and rcs? my ph is 6.0.

if i need to bump it up what should i add?

man, that low kh doesnt buffer worth a damn. i just did a 50% WC and my ph went from 6.0 to 6.6...it will stabilize over the next few hours back to 6.0 because of my soil but these quick swings cant be good for fish...

another way around this is to just do more frequent but smaller changes. like 4 times a week at 10%.

mike, what is the name of that seachem product you use to add more calcium/mg to the water?
