salt mix HELP NOW

[tommyfish]

Hello,
I just did a water change in my reef tank, 25%. I ordered some Reef Crystals, and bot am I sorry! I mixed up the salt saturday, so I could do the change on sunday. I have a 9stage ro/di with ultra violet unit on it. I did the change and my PH dropped to 7.8. I tested some of the new water that I had left.
PH=7.6
Alk-8.4
Ca=420
Mg=1200
Po4=0
I am using the salifert test kits and a pinpoint ph monitor.

alk and cal. look fine, remember reef crystals have highter levels of trace elements. they will be used up in your system and you will be fine

So should I use plain water to do changes with and just add aqua balance to get rid of chlorine?

 

[who dey]

no always use ro/di. you probably paid a zillion bucks for that 9 stage anyway. i use a ph buffer everyonce in awhile to keep ph up

Actually not, I got it at AirWater&Ice. I did add some buffer tonight, But I hate to do that.
