Well my QT system is still killing acro frags..
I took some good advice from Don (ReeferMedic)and placed some live rock into the sump of the QT system. However, I probably need more than what is currently in the sump (~30 pounds) I also have been doing water changes using water from my main system which is doing really well (except for algae problems which is another story). So far I lost the screaming teal acro frag ( my favorite new frag ). The tissue was quickly dissolving away from the skeleton over the last few days and I removed it today. One other small (1 inch) acro frag is going south and another larger frag (4 inches) is doing well. The green chalice is also doing well so far. I'm not sure why the larger acro and the chalice seem to be doing fine whereas the smaller acro frags (1 inch or so) have done poorly.
So far, I tried reducing the lighting by raising the 175W MH pendant, more frequent water changes (every 3 days) and adding some live rock. This problem has been going on for some time and I am really stumped at this point. Any suggestions or comments are welcome....I really need some good brainstorming to figure this out....I feel like I am out of things to try.
Details on the system:
40 gallon breeder tank
50 gallon rubbermade sump
HOB Prizm skimmer
175 W 14k MH pendant (on 12 hours/ off 12 hours - around 2.5 feet above water surface)
4 MJ200 PH faced towards the front glass to disperse the flow
30 pounds of live rock - I plan to transfer more live rock from my main system sump
DIY automatic top off system
PanWorld main pump
Temp: 78 degrees
Ca: 425
Alk: 11 dKh
P04: < 0.01
