Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
:) Yes i liked the original Trilogy lot, but as you have said, I read it in 70's in elementary school. Then In 80's (HS, coledge), I read absolutely every SF book i could get my hands on. At the time I was more intersted at scientific ideas and scientific imagination, and was paying a little...
Assuming you are talking about the Isaac Asimov's Foundation, it is one of the most important, famous and fundamental work in Science Fiction. It received both critical and fan praises and awards. Of course, personal tastes could not be discussed, but that set aside, book in itself is not...
;D
I will have to pass this dive though :( With school starting for 3 kids, bunch of birthdays and aniversaries, my wife will find something really very efficinet for me to sink if I go ;)
This highly depends on the design of the sump and the placement of the skimmer. If your skimmer is inline with the return pup, then yes, if, on the other hand, it is offline (independent pump and flow for skimmer), then that is not true. Excess flow can at least be seen as a "semi-closed loop"...
Strictly speaking you don't need parabolic reflector. Any reflective surface shielding the back and partially the sides of the bulb will be sufficient. On the other hand, if you are more concerned with some easthetic visual effects and want to play with the tight focused beams of light...
2x150MH + 4x65PC over my 75 gives me quite a nice growth of SPS, and in some cases even too much light. If you go 2x250 over 55, you could have serious heat issue.
Sounds OK if the pump is not pumping it higher 6'. If you could manage to split the return from the sump into to or more outlets in the tank, it would be very helpful. However my concern is with the reviews of this pump. Did you read them before buying it? Many people complained about unreliable...
If it looks like Kenya Tree, it could be Dendronepthya sp. - Red Carnation Coral (most often in the trade) but it can also be Scleronephthya sp. or even the Nephthyigorgia sp. - Chili Cactus Coral. Dendronepthya sp, are definitively the ones that like (should be) hanging "upside down".
You can...
It is very difficult to tell what kind of crab it is, from that angle. Even if it is very small now (1/2", right ?), and seem to be scavenging in the sand right now, it could be a potential problem. I would try to capture it and keep it isolated until you determine what species it is. Try...
In general you should replace your bulbs every six months, and while you might not be able to notice the drop in light intensity and change in spectrum, it is there and will be very noticeable if you compare them by putting them side by side. That being said, you could certainly milk a month or...
Waste of money. Soda bottle is as good as that, if not better. Hatching brine shrimp is extremly easy and yo don't need anything fancy. Specially if you use San Francisco mixes. Just a air tubue with slow bubbles (big - no airstone), any kind of lightbulb and soda botle.
There are so MANY solutions. You could go with 2 smaler MHs (with downgrade in watage to 150 or 175). Some of the possibilites (and that is only up to letter G :) ) are :

Non-scientific division of corals in this hobby is usually in the following categories:
Hard corals - corals that build skeletons. They are further divided in the
SPS - Small Polyp Stony. Polyps (protruding part) are relatively small, anywhere from 1/16" to 1/2". Examples are Acropora...
mynd, unfortunately you have completely missed the point that I was making. I have never implied that nano tanks can't have "wow" effect. What I was saying is that in the system of that size you have to focus on a certain type of corals that will be in harmony. And if you have read the article...
