Too aggressive with Zeolites - the result

[Myka]

There is some tissue necrosis starting now Wilson. The Zeovit "pros" on the Zeovit forums have come to the conclusion that the corals have been shocked by nutrients being taken out too quick, as well as several other people commenting that their LPS have reacted the same way when Zeolites were introduced. So I am definitely believing this right now.

I know a mixed reef is a difficult thing to obtain. I never meant for SPS to get in this tank...don't know how they got there.

I have never been much of a fan of phytoplankton, always found it raised phosphate. Although it do notice it increases pods. My Assessor would like that...she eats ALL the pods.

I know there is food in the tank, I have diatoms and a small amount of cyano due to increasing the food type Zeo additives.

The tank is dosed with calcium, alkalinity, magnesium, Zeovit food additives (Coral Vitalizer, Sponge Power, Xtra), Zeovit Coral Snow (so-called biological facilitator), ZeoStart (bacteria food). The tank has Kent carbon, and the Zeolites in the sump, both are passively run.

The Zeoheads recommended I quit dosing Zeobac (bacteria), but to continue with the Start to feed the current bacteria. At one point they told me to stop dosing Coral Snow as it can be aggressive too, but now they told me I could start again. Maybe I should stop...I dunno.

The Zeo product that bleaches the corals is Spur2. I have used this a few times with great results. It affected most SPS (within 48 hours of dosing), but didn't seem to affect any LPS at all. My LPS issues didn't happen anywhere near the dosing of the Spur2. I haven't dosed Spur2 since Oct 18. The Favia started showing signs of trouble on Nov 17, the Symphyllia didn't show signs of distress until Nov 24.

I feel like ripping the Zeolites out and tossing them across the room.
