I agree that ULNS plus high alk = bad... either drop the alk or stop the ULNS, id bet money it fixes your problem

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.

Well there ya go..... You've got ten different potential causes..... Hopefully that clarifies things for ya..... Aren't you glad you asked for advice

You just summed up the sps experience lol.

... and we still haven't scratched the surface on the variables associated with SPS, ha ha!

I might have missed it but has anyone addressed the fact that he's trying to grow light demanding coral under 150 watt bulbs? I wouldn't even attempt it. I know it has nothing to do with RTN but that's not much light for SPS.

I did see that but 150w even over my little solana started to not cut it. Can't imagine over a 180 unless they were those super bright iwasakis.

150watt HQIs are enought light, to low of light would tend to show up as browning and slow growth unless you go extreamly low light. people used to grow nice SPS under PC's and VHO's for some of you younger guys you might have to look thoes up

Depends on which 150HQI bulb is being used. My sps sucked under a bluer 150. Seemed ok under a cheapie 10k but not great. Now under led, growing like crazy with tons of colour.

However I agree with Steve. Not enough light would show up as he said, at least in my experience. My opinion on rtn, is just looking at them the wrong way causes it. Of course thats ridiculous but its how it seems.
