Here's an update on the cube: There was a heat-spike incident (heater stuck "on") that killed the anemone and abalone. I had removed the corals before that to the large tank at work as they weren't looking well. I thought for sure that the bicolor dottyback also was killed by the heat...

Ha ha!

Umm, unless you are a fish - you pee out your nitrogen as urea not ammonium.

If we require reading, we will have to assign grades too....;-) Anyhow, thanks Gresh. I'm glad you like the article.

You guys finding many porcelain crabs? Looks like you are having a fantastic time!

Hi Matt, I've asked numerous sources about getting some specimens. A few warm leads, but no slugs yet. Jonathon (Crabby)

I haven't tried the potassium permanganate treatment yet. I also haven't done anything with manual removal. They are eating one coral, which is dinnerplate sized, so it'll take them a lot of time to munch it all up and have left almost all of the other montis alone. I am going to try an...

Yeah - I'd remove all the montis and dip them. I fear that I wouldn't be able to get 100% of the monti coral out of the tank, as it's encrusted in places. Perhaps the nudis would eat what is left then starve? I'd have the corals in a temporary tank for 6 months or so... Potassium...

Has anyone tried to rid their tank of monti eating nudibranchs using the potassium permanganate treatment that Eric Borneman wrote about here? http://reefkeeping.com/issues/2007-09/eb/index.php I've lost a couple of monti frags already and they are munching on some, but not all of the...

Nice! Perhaps you have motivated a club member to make a 900 gallon tank - half for reef and half for kids.

If they are hard: foraminiferans. If they are soft: sponges. If they have no branches and a little red tuft: worms

That red purple stripe chalice looks great! Let's frag it!

Does the tank look better with LEDs? Maybe. It's way more shimmery, which at first gave me a bit of a headache. But, now I'm liking it a lot. The test will be whether the corals are happier. I'm noticing a lot more algal growth already, suggesting the tank is getting more PAR now than it...

I wanted to change something on the tank. Just felt the itch to screw it up. So, I ripped out the lighting and installed LEDs. Here's a photo of the process. All told, took me about 4 hours of work, and I was able to save the existing wiring on the hood. Next, I want to try growing high...

Here's the tank just after the last swap and the two PC bulbs I've been using: a 50/50 and an all actinic

Here are early pics of the tank after it had been up for about 2 years - before and after addition of a rose anemone. Sadly, about 9 months after the rose anemone was added it crawled into the korralin pump and got munched. I came home one day and the water was an opalescent pink. Did a...

I've been meaning to start a thread for my home aquarium - a JBJ 12 gallon DX nano cube that I started in early 2007. I ran the tank stock for several years. Then I added a korralin 3 pump for circulation. And last week I changed the lights from PC to LED using a kit from RapidLED...

How about a wave wedge at one end? Or a surge tank dump at one end?
