Hi guys.

I was wondering what you keep your alk at. I was maintaining a dkh of about 9, but I've been having hair algae problems. (I've tested water quality - nitrates are below 5ppm and phos isn't detectable. Using RO/DI water, ect.....). Someone recommended that I raise my alk - saying it might have a positive impact on the hair algae. I've raised my alk to 12 so far, and low and behold my hair algae does SEEM to be retreating (some of it is turning a yellowish brown). I was suprised that alk could have an effect on hair algae, but it seems to be working.

Sorry to ramble - back to the alk question. I've noticed my leather corals don't seem to be too happy. None of them are polyping out since I started with the higher amounts of buffer (Kent pro-buffer). So, I wanted to see what you guys keep your alk at and if you had any comments on the leather coral issue.
