Toilet cistern aquarium
Hardly a product a responsible reefer should use or endorse, but the concept is still pretty amusing.
But don’t worry - the fishes are isolated from the flush water and won’t be flushed away.

That's a relief.
Picoreef practicalities
Location isn’t the only problem with the picoreef, though. I really think that the tank is too small…or the rock in the tank is too big. I have a really difficult time changing the water or even testing the water because the rock takes up so much of the space in the tank. There’s about a half inch of clearance in the front and back and just 2-3 inches on either side. It’s hard to start a siphon, clean the glass or test the specific gravity without hitting the rock. If I had a bunch of invertes I’d damage them every time I did anything. I try to imagine a feather duster in that tank and realize that if I had one I wouldn’t be able to put either a siphon hose or a hydrometer into the tank without decapitating it.
Awesome acropora photos

Magnesium and its effect on coralline algae
Since magnesium is a component of the pigment chlorphyll, it is required for all pigmented algae. Magnesium is also required for the formation of the enzyme catalase (Round, 1965), which serves the protective function of breaking down hydrogen peroxide into oxygen and water. Magnesium is unlikely to be a factor limiting the growth of algae in seawater aquariums due to its high concentration in seawater.
Caught a coral larva in my tank today!
just wanted to share with you that I caught what I believe is a coral larva in my reef tank today. Judging by the color and shape, I am guessing it is a brown polyp larva (also since they spread all over the tank like crazy). I will attach a picture I took through a microscope so everyone can see my cool catch. There was more than one swimming in the tank, and I cought one and put it in its own bowl (or should I call it a nano reef?). If I am lucky enough, it will grow and I can observe it. If anyone has an idea on what species this guy is, please let me know!
Fishy Skybridge
Back in my FOLR+cheato days, I built this up to link my 90gal with my 55gal. The fish really seemed to love it, many would take the trip back and forth about 50-100+ times a day. They would actaully have fishy traffic jams in there occasionally, and eventually establish a little fish pecking order (the large trigger was generally not challenged much).
I mounted that little stopcock in the top for easily sucking the air out (and hence water in). I know, I know, red silicon was all that I had at the time, and on my budget, I just make do with what i have.
The lawnmower and snails would keep the tube clean for me, and it was really a blast to have the fish hanging out in the tube over your head watching you eat dinner.

A fun idea, however there is a negative pressure issue with this setup. The water in the highest part of the bridge is at a lower pressure than normal seawater. Having said that, we doubt the minimal height difference will produce enough of a pressure differential to disturb the fish. If the tube had risen to ceiling height then there might be a problem.
Engineer goby, jawfish, and small tankmates
have a 90 gal reef and planning to upgrade to a 210 gal. I like small and medium sized fishes as weel as crustaceans. I am interested in keeping a trio of jawfish or convict blenny / engineer goby. I am hesitating and would like the opinion and most of all experiences of other people regarding compatibility.
1-Would these species represent a threath to small crustaceans (small sexy shrimps, cleaner shrimps, small porcelain crabs, etc.) and to clown goby (gobiodon histrio and citrinis: 1&1/2”)?
2-Is it really a problem to keep them with LPS corals and clams sitting on the DSB?
3-Does their digging disturb DSB’s NNR methodology?

Cleaner shrimp question
I have one cleaner shrimp, and to my knowledge it has eaten 2 of my blue legged hermits!!! Maybe more. I have counted them and I used to have 10. Right this second it is in the process of eating one right now.
Is this normal? Should I not have crabs with cleaner shrimp?

Editor's note: the poser of this question is mistaken, common cleaner shrimp Lysmata Amboinensis are far too fragile to kill any kind of crab. Personally I would suspect that the poster is seeing discarded post-molt hermit crab carapaces.
