Aquarium Filter Size
Aquarium filters are critical components of both freshwater and marine aquaria.Leibel WS (1993) A fishkeepers guide to South American cichlids. Tetra Press. Belgium pg 12-14. Aquarium filters remove physical and soluble chemical waste products from aquaria, simplifying maintenance.
The relative extent of something; a thing's overall dimensions or magnitude; how big something is
Each of the classes, typically numbered, into which garments or other articles are divided according to how large they are
Extensive dimensions or magnitude
(used in combination) sized; "the economy-size package"; "average-size house"
cover or stiffen or glaze a porous material with size or sizing (a glutinous substance)
the physical magnitude of something (how big it is); "a wolf is about the size of a large dog"

The coolest thing is happening in my aquarium tonight! (+4 in comments)
It's around 2am Monday. I had just finished feeding the fish and watching them for a little while. I had noticed a couple of the snails were moving around under the sand. We have about 10 Lettered-Olive Snails. They're nocturnal and are usually buried under the sand. They only surface to eat.
Anyway, I turned the light out and sat there for a few, watching to see if they would come up while I was there (just ambient room lighting). One surfaced and went right back down. Suddenly the 2 fish started spazzing out! I didn't know what was happening. Was something wrong in the water? I turned on the tank light and couldn't believe my eyes!
Millions of little dots filled the water and about a hundred translucent egg casings the size of a pencil dot floated around. They're snail eggs & larvae. The fish are gobbling up everything they can so I don't know what if anything will survive. And my filter is going too, so some are getting sucked up.
From what I read this is extremely rare! I'm so excited!!! And a little nervous.
If they all die, will it pollute the water? If some survive, will it be too much of a strain on the tank, water, food, etc.? Dd this happen because they're happy or about to die? I don't know what to do now but it's soooooo cool! :-)
I tried to take some photos of the event. They're hard to see though.
The pride and joy of Osaka Aquarium--one of the world's biggest tanks, housing a breathtaking whale shark. He's one of only a handful of whale sharks in captivity in the world. The name whale shark comes from both his size and his crazy whale-like eating habits--he just opens his mouth all the way up and swims along, filtering out krill, plankton, and the like. Whale sharks are the largest shark in the world, yet they pose no threat to humans. Makes you stop and think about how we make such snap judgments like "sharks are dangerous." Stereotypes are bad, even for the animal world!
The name Marbles comes from Bret, who decided to name him while we were there :)
