The Wonderlights (wide spectrum self ballasted mercury vapor
lamps) are marketed by the Public Service Lamp Corporation.

I have a copy of the spectral output in front of me

Peaks at 410,510,550,650 710 nm.  The spectrum is extremely
broad, with a lot of intensity between the peaks, unlike
many fluorescent bulbs.

There is no mention in the product literature of the absolute
light output.  They do mention that, due to the tungsten filament
ballast, that these bulbs are less efficient than remotely
ballasted mercury vapor lamps. 

I will be setting up a plant tank with my wonderlight and will
report on the results.  I don't know whether they  are better
than fluorescents per se, but they do have several advantages.

1.  They are a flood bulb with an internal reflector.  This 
couples more of the light into the tank.  The bulb does not
need to be inches from the water. Because the bulbs are compact
and emit a directed beam it is easier to get very high intensity
in a small area as compared to fluorescents.  Thus even if
the bulbs are not as efficient as tubes (which I am not at all
sure of), one can fit more light into a smaller space.



2.  The bulbs last much longer than fluorescents.

3.  If you use expensive wide spectrum fluorescents such as
vitalites or tritons then the perwatt cost of the wonderlight 
is lower.             

4.  The fixture is trivial to install and wire because it
is an ordinary incandescent socket.

   
   Disadvantages

   1.  I don't know if the total light per watt that the plants
   recieve compares well with a well designed multi tube
   fluorescent fixture.

   2.  The flood lamp is high profile and needs a lot of open
   space over the tank.

   3.  Nobody seems to know anything about them.


   I think that metal halides are the best bulbs for growing 
   plants, but the wonderlight setup is a fraction of the
   cost of metal halides.

   By the way,  metal halide setups for $169 are available
   from hydroponic grower supplies.  This is cheaper than
   that advertised in the aquarium rags.

      Thats all for now

Actually, I checked and Ca(OH)2 has a low solubility too, compared to CaCl2. It
is about 0.077g/100cc. I'll bet that CaCl2 would indeed be the easiest way to
add Calcium; since its solubility is so high,you may be adding far more than 
you need, indeed far more than you can possibly add with the hydroxide. Figure
out how much Ca you are adding with a saturated solution of the hydroxide and
then figure out the relative volume of saturated chloride solution  you need to
add to get the same amount. You probably shouldn't even saturate it.

Eric

P.S. Oops! I gave you the hot water solubility figures. The cold water figures
are at 20 or 25 degrees C, usually, and are CaCl2=74.5, CaCO3= .00153, and
Ca(OH)2=0.185. All figures in grams per 100cc. Yes, the hydroxide solubility is
higher in colder water; has to do with the enthalpy of solvation.

Just to clarify one point, the author of the article did withold some facts
according to Julian Sprung.  Julian gave a lecture at the San Francisco
Aquarium Society meeting last month in which he explained how he had
gotten some type of coral to spawn and gave pictures of the spawning
coral to the author but which the author failed to publish.  Julian
said that he had explained in great detail to the author how he had
gotten the coral to spawn but that when the article came out there was
no mention of the spawning, and in fact the author had stated something
to the effect that this same coral had never been spawned in captivity.
Julian did not state the name of the author or publication, so I'm only
guessing that this is the article which he was refering to.

Net folks,

I am in the process of setting up a 55 gallon marine tank which initially
will be a fish only aquarium, with the option of converting to a mini reef
in the future. For filtration, I am planning at this point on using only a
Eheim 2217 cannister (I also have a spare 2215) and maybe adding a
Sanders 350 protein skimmer. Although I don`t think I will need any
UGF/RUGF filtration, would it make sense to put in UGF grids now (before
the substrate is in) just in case. The expense is not a very big one,
but I'd rather not waste money if it is totally superfluous.
Any (and I mean Any) advice would be much appreciated.

Also, are there any marine aquaria books which are recommended for someone
who is not totally ignorant, but still setting up his first marine tank?
Any other sources of information (other than the faqs which I have
already read)?

Well, your starting to sound like a card carrying member of the NRA (gag!).
Green Peace killing baby seals?  I don't believe that.  (please enlighten
me there, so I don't think you're making unsubstantiated claims).  

Commercial industry is certainly not all about being honest and forthright
in never leading the public astray, etc.  If you want to criticize your
"eco-nazis" under those terms, you have to criticize all of society.  If
you have lost that much faith in modern civilization (not hard to do), then
let us know that is where your coming from.  You would then think there is
no hope what-so-ever to save the environment, thus everyone who does is a
screaming zealot.  

Nazism is not about fringe groups lobbying for what they believe in.  It
is about central dictatorial control of the entire society en masse.  It
is about exploiting hatred for power.  It is about genocide.  Don't use
the term anymore, please.  I promise I will make an issue of it every time
you mention it.  (Now I am sounding like a overzealous lunatic!  But I sure
don't feel like one).

I now admit that I may have over-reacted to the original Audubon article.  But
the gist is accurate.  There is damage being done to reefs, and we as a group
should be sensitive to the problems, instead of reactionary.

I've seen and heard references to a "Dutch" type of aquarium, specifically  
when discussing plant tanks. From what I could gather, I think a "Dutch"  
aquarium is one with no filtration, just aeration, densely stocked with  
plants, and having a substrate of sand and soil. In other words, a really  
natural aquarium.

Is this correct? Could someone more knowledgeable accurately define the term?

Knowing that many times "traditional" bio-filters are undersized, I asked
a clerk at That Fish Place about BioLife filters. He confirmed my 
suspicion that, at least for the tank size they rate them for, they are
inadiquate as a bacteria farm. He made no mention of their adequacy in

Hope this helps... and isn't too disappointing.

At the suggestion of some fellow *.aquaria readers I had a CA buddy
purchase a RO system at "Price Club" and ship it to me.  I've
installed it now, and it appears to be working very well.  The fit and
finish are excellent.  The system consists of a sediment filter,
carbon filter, TFC reverse osmosis filter, automatic shutoff, 3 gallon
pressurized storage tank, post storage carbon filter, and an "air gap"
faucet.  This complete system was $169.  This is much cheaper than I
have seen in the aquarium mags.

I haven't measured the output of the system but I'm guessing it is
producing about 12 gallons per day.  The system is manufactured by

Premier Manufactured Systems, Inc.
4737 North 43rd Avenue, Suite 1
Phoenix, Arizona
(602) 931-1977
(800) 752-5582

The fellow on their 800 number was very helpful in talking me through
a minor bug in my system.

We are using the system for our drinking/cooking water, to drive our
icemaker, and to produce water for weekly water changes in our 36
gallon aquarium.  The water tastes much better and I won't have to
make those trips to the grocery store for distilled water.

Also, the latest "Damark" catalog has a similar looking system for
$199.  I have no knowledge of its performance/quality.

Huh?  

One: how are you managing to get a protein skimmer to run on a freshwater
system?  (i.e. if it really works, what's the manufacturer and model and
price 'cause I will be getting me one!)

Two: how are you managing to decrease the nitrates level with a protein
skimmer?  I though protein skimmers only pulled organic carbons out of the
water and the idea was to get them out before they break down to ammonia and
get metabolized to nitrate by the bacterial beds...

I don't recall which magazine(s) did the greenpeace exposes a few months ago,
but I will attempt to find the exact publication (no guarantees).  The

greenpeace.  I think alt.activism or ACTIVE-L mailing list had something

Sorry about being so vague, but I did not at the time think to save the

screwy actions like stuffing the International Whaling Comission with 
land-locked 3rd world nations and filming a big-name movie star saving the
"life" of a stuffed baby seal did not bother me all that much in the past
because it was in the name of the "good cause".  But when they pay to
slaughter baby seals in order to film a propaganda tear-jerker...  

Fuck it.  I prefer to give my money to Earth First! because while they are a

This may sound strange, but I just thought of something...

Could you take one of those little plastic balls that have bells
in them that look like little cages?  You could cut a hole in the 
side to remove the bell and slip it over the end of the intake
valve.  This just came to me while taking "5" from studying for
