I wouldn't add buffer. 7.8 isn't terrible and I'm not a fan of adding buffer to begin with. Adding directly to the aquarium can burn the gills of fish and is not good for coral. You would be better off testing your alk as that is a natural buffer.
Good to know. Thanks both.
Salifert ALK/KH test kit will be in hand on my way home today. The stuff I bought yesterday is Kent Marine Superbuffer-dkh. I have dosed once. Toss it?
You guys were right on it. We (me and it) are on the right track. I am raising KH slow and steady, but we are on our way to 9 and looking very good. Thank you for the help.
Be careful because I killed most of my xenia by accidentally overdosing part A of the 2 part and that made my alk so high it was sky blue and my xenia melted within the next 12 hours and some other corals suffered too.
Go to liveaquaria.com they have a nano fish section but I really like the catalina goby . And oh ok I gotcha sounds interesting. You have to have fish while cycling because they create a good bioload for your tank to finish cycling.
