I seem to be slowly loosing zoas. I've been away from the tank for a while with work and found about 5 plugs empty. Seems that only the pricey stuff is vanishing :cry: A few have a brown/green film on them. The tank is a 50 gallon brute with 4 small powerheads (koralian nano 425's) and low light (4 T5s about 18 " up to 8" of water - PAR about 100 max) The light bulbs are old, probably a year. I'll get new ones ordered this week. I did a H202 dip on the king Midas - the original polyps are gone, only the new growth on the side remains. In another tank, the Galaxy's wont open, but look clean. Green cloves are melting and have a film on them. also did H202 on these.
I did miss some water changes and got caught up with a few larger ones (12% 3 times in one week). losses are still happening.
The tank is connected to the mixed reef which is doing great and ZOAs seem to fair better there (no loses if that is a measurement). The mixed reef has dual halides.
SPS look great.
KH- 11.5 (this crept up on me, usually 8.5. dropping about .5/day right now
Ca - 430
PO4 - 0 on hanna
NO3 - showing up yellowish instead of pink? usually between 0 and 1
Mg 1400
Salinity 35ppt against calibrated refractometer
If the flow is too low I can try to increase, I struggle with getting flow in the tank because its so shallow. any advice is appreciated!
thanks!
