400 gallon project

[untamed]

Since December or so, I've been having my same old problems. Coral began slowly dying. Last time, I struggled for a year before finally replacing my skimmer and adding ozone. That solved my problems at the time, but I was never sure if it was the skimmer or the ozone.

I've lost all my gorgonians and the rest of the coral is slowly declining. Here's a couple of photos showing how unhealthy some look at the moment:



A few weeks back, I confirmed that my ozone generator was fried. I just installed this replacement unit... an Ultralife UZ360. This kind of generator doesn't require an air dryer and should be more reliable than my old unit.


If this doesn't work, I don't know what I'll do. I don't see the point in paying for all that electricity if the coral is just going to die in the long term. FOWLR here I come!!
