Yellow H. magnifica

Your tank looks very natural Minh. I really like it! Although anything with a big slobbering ritteri in it gets me excited!
 
An inverted 4 inches glass jar.
I got to get some rock and coral out of this tank. They are growing our of the water and I have to re-arrange to get them back under the water.
 
I just read through this whole thread. Amazing! I love the H. magnifica! My lfs has a few anemones too, but compared to your Orion, they look very sickly.

How often do you change water in your tanks? What are your nitrates at usually?
 
I try to change about 30 g every month or 6 weeks. This tank is in my office so I only use tab water to mix the salt (six 5 g buckets). We do have an RO drinking water station so I top off with RO water and mix salt with tap water. You should see my office the day before I change water. Water buckets everywhere. (I have three tanks in my office)
I used to added Kalk but lately I just use three parts additive from Bulk reef supplies to keep Ca, Mg and Alkalinity up.
The sand bed always keep Nitrate not detectable. For stability of the tank, IME, nothing beat a sand bed.
 
Are you referring to a DSB? Is there enough substrate in your tanks for a DSB? I may have to add some more live sand to my tank to achieve a DSB but I have been thinking about it.
 
I got about 4-5 inch sand bed in this tank. Mixture of fine sand and coral rubles. After 4 years or so, the fine sands are all in the bottom and the coarser stuff on top.
 
Amazing. How long does it tank a DSB to become mature enough to start reducing nitrates?
Very quickly. In days as the nitrogen waste built up, you will start to see nitrogen bubbles in the sand bed. If you don't grossly over feed a reef tank, you will not have detectable Nitrates in a tank with a DSB. Other micro nutrients will still continue to build up so water change is still need (Phosphorous export and replacement of micro nutrients) but you don't have to do it because of nitrates
 
Another question for you Mihn. I already have a small sand bed, about 1 inch. If I add 3 or 4 more inches to the existing sand bed, will I have significant die off? Is this a risk to my clowns? What would you do?
 
I would just add the new sand on top of it. There will not be significant problem. I would get he new sand, wash it or do whatever you want, then soak it in old tank water for a week or two then add them to your tank. Soaking the sand with tank water will help coated them with bacterial and get the water clear much quicker. Adding dry fine sand to a reef tank will cause you to have a very cloudy tank for days.
 
Got a new Magnifica, red base. Here he is:

Very nice Minh!!! Man, almost makes me want to try another. "Almost." :lol: I still remember how big mine got to and I don't have space like that in my 280g. (I call it "capped" with the two gigantea and one RBTA and one mini-maxi carpet.)

But I *do* love these red based magnifica's ..... sigh!!!
 
Looks gorgeous Minh!

Did you lose the other Ritteri? Cant remember exactly if you lost it due some sort of power issue or if I'm confused.

My apologies if I'm confused. You get some of the prettiest Ritteri's I've seen out in your neck of the woods...

I got greedy and added a hot pink tipped Magnifica that was sick (I did not know, it seem fairly healthy at the LFS but just came it). It died and transmitted what it got to my two other Magnificas. They died 2 weeks later.
The hot pink tipped Magnifica was so beautiful that I feel if I don't get it some one else will, so I got it off the bag as it arrived to the LFS.
From now on no new anemone will go into a system with other establish anemones until I am sure that they are healthy.
 
Ahh.....

Yeah did that once myself. I almost lost my brown based Magnifica due some sort of bacterial infection about a year into having it. I wound up pulling it from the display and treating it with doxicyclene. I did about a 12 hr dip IIRC and it pulled through. Looked like crap though.....

Sorry to hear of your losses Minh.

The anemone you have now is gorgeous!!!

A. percula color change with this Magnifica. This color shift was not observed with some of my other Magnifica. As the picture showed. The black become less back in some part and the border between black and orange is blurred and some of the orange part become black. This two pictures is of the same pair while with my Malu and then with my Red Magnifica. The fish (and the tanks) are healthy. Both time they are spawned regularly.

My Rod's Onyx went through a weird brown phase with my Brown Magnifica.

They've been with that anemone since I got it. But for some reason around one year in with it, they lost the black and went brown...

One month with Ritteri before being a mated pair 04-06:

Brown phase while spawning, at 1.5 years with anemone in Sept 07:

Same anemone and clowns for the entire series of pics....diet has been pretty much the same the entire time. Uncooked shrimp pieces, uncooked scallop pieces, occassional mix of PE mysis, Hikari mysid, Rod's food, spirolina enriched brine shrimp....

The female is now pretty much solid black....

Sorry for blowing up your thread with pics of my critters but I wanted to show you that mine went through that too and then darkened back up.

One thing I just realized while typing this is that the anemone "sting" did not affect me the first year or two I had it, which happened to be the same window the clowns went through their weird brown phase. The tentacles were sticky and the feeding response was good, but it didnt burn me.

After that two year period, and currently, the anemone will burn me and leave a nasty welt for a couple of hours, to a few weeks depending on where I'm stung by it. Hands, couple of hours, inner arm while cleaning the tank, weeks.

I know that Carpets are notorious for being fish eaters and having a potent "Sting"/powerful nematocysts. It is also documented that clownfish in Carpet anemones go melanistic and it has been hypothesized that the stronger nematocysts cause the clowns to get darker.

Could it be that it took my H.magnifica about 2 years to get back to full health and develop the more powerful nematocysts that will burn me and caused the clowns to go melanistic again?
