How to nuke a 300g SPS tank

O well my tank is not big as yours and I don't have much corals as you have. I think automating the process would take away my personal touch to my humble reef.

I hope your corals recover soon. Best of luck.

This is my second tank with a doser and the first one has worked flawlessly for years. This one was working fine too if not for the broken connector. It was a used doser and I would have found the issue out if I had kept up with the testing. Even if I had found it down around 3, I could have slowly raised it up over time and everything would have been fine.

Thanks Andrew.

Because I was away a lot then, didn't have time to closely monitor everything, and by the time I discovered the problem the damage was done. Doesn't sound as bad as yours though, as my alk just went below 6 (normally at 8 or 9). But I still lost some prized SPS.

Surprisingly, some corals (incl some SPS) were not affected at all. However, it took about 3 months to recover from that before my SPS was happy again, with good color and growth returning. And I should have known better, too, as I have to regularly watch that alk return line so it doesn't plug.

Thanks Walter. That was the biggest surprise for me. As the Alk was going down, corals continued to look great, it was only after the Alk spikes in the water change did anything happen. I can handle brown coral knowing things are good now and they will return to normal soon enough.

Actually mine got worse too after I corrected the alk, and then took 3 months to fully recover. Having said that I also had some other tank issues (high nitrates after I had disconnected my bio pellet reactor) just before this, and the low alk was the just final tipping point. But again, some SPS were never affected, and none of my LPS or soft corals even noticed anything amiss.

I think you are right, though, alk spikes make it worse. That's what did mine in, too, I think, when I raised it too quickly (didn't have time to fool around as I was not home a lot at that time).
