I will be honest with you, my tank looks like crap now. One year ago, it was awesome. It had been stable for years- zero ugly algae, and a very full and healthy looking tank with simple maintenance. But it's been a rough year for my tank. Here's what happened:

First mishap- heater malfunctioned and got stuck "on." Cooked the tank to about 98F and I lost a ton of coral and fish. Only the sarcophyton, gorg, red sea xenia, shrooms, and bubble survived. My colt shrunk from 9-10" across to one inch. Just melted away.

Second mishap- I moved. A lot of the coral fragments did not survive the move, as careful as I tried to be. Luckily I had a lot of fragments of each kind so I didn't lose anything that would not grow back.

Third mishap- I moved AGAIN. Again, I lost some coral, but nothing that wouldn't grow back. This time when I moved, I added a couple inches of sand to the bed (I know, I know). It is going through a sort of mini-cycle now, with unsightly algae that I haven't had for years.

Ok, one more mishap- My significant other dunked the lights into the tank. She even got a bit of a zap. Tank was without lights for 5 days or so. They were compact fluorescents, which I replaced with 250K MH.

Now that I have MH over the tank, the corals are bleaching, the bubble won't extend much and has been steadily shrinking, the sarco doesn't extend its polyps much, the xenia isn't growing like a weed, the blue shrooms are small and turning gray, the purple gorg has totally died and is covered with algae. I'm just depressed with the whole thing.

BTW, I realize that the lighting is more powerful. I raised the MH to about 14" over the top of the water, and reduced the photoperiod to about 7 hours per day. I have done lots of healthy sized water changes, and continue to drip kalk. I expected to see a rebound. It just sucks because my tank was just really great, and now it's blah. Fish are healthy and happy, but corals look like junk. I can't seem to get anything back to thriving.

Any suggestions would be helpful.

Thanks,
HD

Hey HD, check my thread "Trying to bring my tank back..." You will see you are not alone and maybe pick up some tips you can use.

How is your water flow? Mine has started to turn around since I upgraded my pump. I think my old one had lost more of its flow rate than I realized.

Do you have an old DSB?

I have quite a bit of flow and no dead zones.

Not an old DSB. I had a 2" crushed coral bed before, and when I moved the second time I added a couple inches of sand on top of it. Should have just stuck with the CC.

Interestingly, after I moved the second time and added the sand, I got an explosion of my pod population. For some reason, over the last two months, it seems to have dwindled. [scratches head] No shrimp, few crabs, and no pod-eating fish.

I would cut the MH lighting back even more. Try around 4 hours to start and work up from there. Moves tend to reak havoc. When I moved my tank last yeat it took 6 months for things to get right. I am mid move now and my holding tank is not doing well. I am hoping to get the new tank finished by the end of the month.

I think you are right, Waz. I've been cutting back the MH step by step, but maybe I need to start real short and go up step by step. I can always raise it up more too. It's pendant lighting, so no prob.

Thanks, bud. Good luck on your move!

Sorry to hear that, HD! Sounds like what you need is time...I have no doubt you will get your tank back to its original glory. :)

Yeah, time for sure, Chris. I figure I am going through a mini-cycle with the new sand, and just have to keep up with more frequent water changes like I did way back in the beginning to get the algae under control. Honestly, the algae isn't bad. Just a dusting of diatoms for the most part. I'm more concerned with the corals that just aren't bouncing back.

I think you're right HD and it's having a mini-cycle.

I also vote for cutting down the photoperiod and am thinkin' good thoughts for you.

I vote for moving the pendants further up and leaving the photoperiod be a normal one (12h).

Thanks, Mouse. That's what I'm hoping too. I think the reduced lighting schedule may already be having a positive effect.

I'm done moving now. I had sold my house in June and started building a house, but I had to move into an apartment for a few months while the new house was completed. It will be years before I move again, Lawd willin'.
