Zoas in trouble. help!

[rkelman]

Over the last 6 months my Zoas are getting smaller. The polyps are quite a bit smaller / less colorful. Almost every type I have. (6 I think) My other corals are healthy and growing. My KH Keeps dropping to 8 My calcium is ok. I keep the salinity at .026 Nitrates are 10-15ppm. The only other thing happening that is strange is my Chaeto growth has slowed to a creep. It was growing like crazy. I can't remember the last time I trimmed it. I have replaced the bulb in my fuge but that didn't help. I did get lazy on my water changes for a while but I've been doing them the last couple months and it doesn't seem to be helping.

Hmm I might have to Thanks. My polyps aren't closing though. They are acting like they aren't getting enough light and are shrinking. Maybe bulbs? My sps are growing though...

Any other ideas?

the opposite? too MUCH light, they may be retracting from it. If it wasn't enough, they'd be reaching for it.

ever feed them? they'll take cyclop-eeze

I do feed cyclop-eeze. My lights havent changed. I've had most of the Zoas for 2 years. Thanks for the suggestions
