Also get some Mg. I used Kent's product. Works well. The only test kit I could find was Salifert's at J&L. Don't know what AI has. BTW, AI is closed today

Damn...I forgot its a holiday for everyone...

Here's the Reef Chemistry Calculator to help you figure out how much Mg to add:

Make sure you use the link to the Tank Volume Calculator to get things right. Take inside measurements of your tank:

What kind of wonkiness did you have going on in your tank Danny?

I had low Calcium (200 or less) high Alk, over 12meq/L and high Ph 8.8 at one point. I don't know what my Mg was at but I can only assume that it was low as well. Mg makes you calcium bio-available so it is pretty important.

That sounds good. I know what I'll be doing tomorrow!

Thanks Bev!

Greg, if your Alk is really at 16 dKH then they will close up for a while, until things balance out again. Exactly what mine did a while back.

Greg,
GSP's as well as Gorgonians do this from time to time and it is perfectly normal. Encrusting or matting polyps and corals do this as a means of house cleaning, they close up for a week or two in order to shed a new layer of film off there mat's or to simply flush away debris that has accumalated over time. I wouldn't worry for now, when I use to keep GSP they would do this every 3-4 months in my tank. All three types of my branching gorgonians that are 8yrs old do this every few months for usually 3-4 days, with GSP this cleaning period is usually longer.

Thanks for the info. I'll wait it out and see if they come back. I'll try to get my parameters back in balance. I am not sure how but I am sure I'll get it sorted out.
Thanks,
Greg
