Calcium and magnesium are low.....that may have something to do with it......or it could just be the way your corals "act".......I had a patch of gsp that would close up for weeks at a time, I kept thinkin it was dead....

Thanks for the replies, anyone else

If it is anything like the Devlis Hand leather it might be molting. Both my DH and TS seem to do it.

Ya actually my devils hand does it also good point thanks grizz. any ideas on how to keep my perimeters up. how would one dose when adding 5 gallons of top off every few days. i suck when it comes to figuring out how much of all the additives to add.

All I do and it seem to work well is mix your water/salt to match tank salinity. Then test the water for Mg, Ca & DKH, add your additive to bump to required levels. I have found once I had my Mg up to 1400 ppm that the Ca & Alk balanced out and stayed.

Start with a small amount of additive and record how much it bumps then you have an idea of how much you need to bump it to where you want it. Does that make sence to you?

Ya kinda, So I would add the additives only when I do a water change, or when I add my 5 gallon top off every other day...Sorry I am stupid when it comes to this ****.

oh and what test kits do you guys use
