What is a HOB filter ?

It seems so obvious to you that I can't find it anywhere (I'm not a native speaker).

HOB - Hang on Back Filter

benigne 76 · 01-22-2008, 02:08 PM

Ok, thank you very much ! They're not very common here, and we call them gutter filters.

Yeah, we just call them Hang On filters, because, of course, you can hang them on the side as well. When I first heard the term HOB I thought it was like the hob you mount a stovetop or a bath on and it was some kind of swish built-in thing... I was a bit disappointed to find out it was a hang on.

CF = Compact fluorescents
PC = Power compacts
(are these the same?)

HO = High output

But when everyone talks about the wattage on a high output do they mean the power put in or its equivalent in incandescents (ie. if a 23W high output is equivalent to 125W of incandescent lighting)? Because it does seem really bizarre to base WpG on the power consumption of a high output light.

What does T5 and T8 mean?
(I've been thinking the T stands for something synonymous with "next gen")

K = Kelvins
nm = nanometers
lux = lumens per square metre (this isn't technically an abbrev. is it?)
CRI = colour rendering index
PAR = Photosynthetic Active Radiation/Photosynthetic Available Radiation

Also live food seems absent:
BBS = baby brine shrimp
BS = brine shrimp (or the other common usage)
mw = microworms
bw = blackworms
ve = vinegar eels

The terms high output (H/O), normal output (N/0), and very high output (VHO) are not referring to the wattage of the bulbs but to the frequency of the ballast that drives the bulbs.

On the "T" thing as you describe it the T is representative of the diameter of the bulb in eighths on an inch, for example a T-5 is 5/8" in diameter and a T-12 is 1 1/2".

What is BUMP? I see it in threads that noone has answered. Just curious.

Bert H · 04-01-2008, 04:43 AM

When noone has replied to a thread for a while it falls on the list of that particular forum. Bump merely is a way for someone to bump up the thread to the top of the list of threads in that forum hoping it will get more attention from folks looking at it. It's just a meaningless post for the thread to rise back to the top.

Thanks Bert

I honestly, for the most part don't like a lot of these "short cut" words. I don't feel like I should print out a list so that I can refer back to it to understand some subject matter. But then when I don't print one and I am gone from the forum for a while I come back and have a hard time, then I find my self back at this list, and that is quite annoying.

To have refer to a reference because people don't want to actual type a word out, what the heck. I thought typing was a faster form of writing already. What a side track!

I am sorry I just have a problem when I am engulfed into a story or leaning and then these capital letters come up that are not explained in parentheses, it's like being out of the loop so to speak, and/or not in the "click".

Just my to sense. (Thank you for the list though)

It would be thoughtful if people more often would use parentheses to label this kind of thing in the first place

EI
Estimative Index?
