what is best for a reef tank...140 gallons. I will take either dkh or meq/l values. currently I am at 9.3 dkh and 3.31 meq/l

thats pretty much where it needs to be, most say 8-12dkh and 2.5-5meq/l

Right in the sweet spot. Mine's around 10, goes to 11 when I do water changes because the new water has really high alk if I don't let it sit for 2-3 days.

What salt and buffer do you use? That sounds lie a good reading, but if you use seachem products (especially budfer or salt) you can go a little higher.

What type of coral are you keeping?

I have both hard and soft though many more soft than hard. Mostly mushrooms and zoos. With a bottlebrush, montipora and mille. Oh and a merletti and acan.
