Acropora tip burn

[Jason McK]

The Reason I asked about the Bacteria based systems is that I did not want to recomment UV or Ozone to someone running that kind of sytem. Both UV and Ozone would destroy the bacteria.

This is my thoughts as Well. I think Brad had a treatment for vibrio at one time

When I neglected to change the UV bulb, the bacteria came back and I slowly lost all of my Acropora.

Ya, went to the doctor and convinced him to prescribe an antibiotic. Seems to have worked. Can't recall what the med was, but I'll look it up.

tony, I'll talk tou you offline about the symptoms I had that put me in that direction.

These pieces pictured haven't died yet, they are pretty much as shown at the moment. However given past corals as a guide for what to expect, there is no hope of recovery at this point for the pictured corals. Well, maybe not the hoeksemai as yet per se, but I am greatly distressed to see the white starting to form on that piece, up until this weekend it had seemed to do really well. It did get knocked over the other day though so I suppose it could just be distress from the fall and landing on something, but ..... I suppose the more realistic explanation is that it's just this coral's turn now.

I'll consider UV or ozone at this point .. clearly me focusing on the parameters, hasn't really netted any results, so I have to broaden the scope of what to consider.

So it looks like J&L sells Coralife and Pentair Aquatics brand UV, and Ocean Aquatics sells Current USA. Are UV systems created more or less equivalent or should one steer away from the less expensive models? What about Ozone? Is that a better option? It looks like an ozonizer with controller will cost roughly double that of a UV. (Oof )
