Brain cramp Alk question
 

My alk. is running a bit higher than I like it in my 190g (12.2 dKh). Do I turn up or turn down my C02 bubbles?

turning down your bubbles will lower your alk, turning down your effluient will lower your calcium.

Thanks Willow - that's what I thought but the more I thought about it the more I was unsure! My calcium is a little high as well at 460 so I will turn down both.
