Dieing SPS

[daniella3d]

I almost lost all my zoanthids when I changed to H2O salt. Other people have reported they lost a few of their SPS when switching to H2O salt, especially digitata. When I returned to IO Reef Crystal my zoanthids came back. I never saw any effect on my SPS though.

Just curious but what salt did you use before and why/what did you cange for?

I changed because I thought that I would not have to dose any more with a stronger salt but I was wrong..it was more expensive and I had to dose just the same. Why did you change?

I agree with Brett. Don't put your LED lighting over the tank until you have it stable.

I would look closely at the biopellets as a possible cause? If not directly, then perhaps indirectly. Low nutrient systems are know to be less stable. Your Alk is also high for a bioplellet system. Others have reported problems when their Alk climbs over 7.

I do have a question for the other posters - perhaps it will also benifit the OP. I changed salt about 3-4 weeks before my problems began. I'm not convinced the problem is the salt itself, but could the change in chemistry have caused the problems? Should I change back (another change in Chemistry) or should I ride it out?

Good luck with your tank Milad.
