Well, some of it, like the changing lighting, sounds nice, but the whole
thing reminds me of computerizing a model railroad - takes all the fun out
of operating it :-).

And with the number of heaters I've had die on me, I'd be really leery of
building one into the canopy unless it was easily replaceable. In fact,
that would apply to most of the components you've imagineered.

I'm going to make a prediction that the next major leap in aquarium
design will be the canopy. I've watched technologies evolve, filters,
filter media, heaters, lighting technologies, feeding systems and water
parameter related equipment. Occasionally some of these technologies
have imbedded themselves into the canopy. For example, 8 years ago, an
Italian aquarium manufacturer had an auto-feeder built into a canopy with
T6 fluorescent lighting. They were a little ahead of their time.
Marineland has a line of tanks with their filters built into the canopy,
and the design has persisted, even with many drawbacks.

The canopy of the future will resemble what we have today, but will be
much bigger, possibly 8 to 12" thick. It will incorporate things like:

1. Filter system
- integrated biowheel, and sponge media which would be serviced through a
hatch in the canopy.
- backwash capability into overflows (see para. 7. below)

2. Storage
- nets, test kits etc

3. Heater
- why use precious aquarium real-estate for an unsightly heater

4. Food storage
- empty/mix all your dried fish foods, pellets, flakes, freeze-dried etc
into a compartment which is sealed when the hatch is closed.
- there is a screw-type feeder with rubber blades (to keep humidity away
from the food) operated/programmed from a keypad (integrated into the
canopy)
- level indicator (proximity switch) provides visual indicator of low
food levels (ie: by reversing light operation to get your attention)
- filters would automatically turn off for 10 minutes during feeding

5. Light System
- staged lighting, programmed from same keypad
- dawn/dusk lights, small halogen making a spot light effect, with
ripples shadowing the substrate, used to transition to/from nightfall and
daylight main lighting
- main lights (two CF groups, morning 1/2 on, mid-day all on, and evening
1/2 on again)
- programmed variability (cloudy periods) to reduce algae (currently done
with timers set to 1 hour off)
- twilight lighting (typically red or actinic) not programmed, set
manually, for those bottle of wine by the fire late evenings.

6. Ventilation & Cooling
- all that lighting will require that the ballasts are in a separate
vented area (separate from the air under the canopy)
- stainless steel tubing (with cooling fins) replaces conventional hoses,
allowing atmospheric cooling using a small fan triggered by a
thermocouple.

7. Water/Atmospheric control
- pH regulated through CO2 injected inside canopy (or skip to next item)
- low pH amber/tannic appearance through black-water concentrate pellets,
or processed/compressed leaf pellets
- kH regulated through baking soda pellets
- continuous monitoring of conductivity (TDS control)
- plumbed directly into home's DWV and cold water supply line (for
continuous water changes through a drip system)
- thermocouple (replaces thermometer), to activate dynamic cooling
(para.6) and reduce lighting to cool as required. (heater's thermocouple
would be a separate unit in-line with heating elements).
- backwash cycle which would pulse water in through the gravel, trapping
mulm in screens located near overflow pipes

8. Power distribution
- plug the canopy in and all peripherals connect to canopy's integrated
GFI protected power bar.

9. Water Purification option
- clear plastic bell fits on top of canopy (semi-integrated), housing
various bog/terrestrial plants whose roots would strip out any remaining
NO3 from non-planted tanks (silk plants would make a come back, but some
people will always want real plants).

10. Live Food option
- habitat section in canopy for growing small creatures (ie: white worms
in earth, feeding off decay from mechanical filtration stage, or mysis
shrimp hatchery etc). Hatchery occupants will randomly 'escape' into
main tank to be eaten.


Did I miss anything? Today, this equipment & electronics exist
separately, much of it in high volume consumer goods, except for:
a) the canopy itself (fairly straightforward mould with several options
and expansion panels to include odd sized aquarium dimensions).
b) the canopy horizontal filter (plastic moulds) utilizing twin
(redundancy) generic powerheads
c) the controller and fairly straightforward programming
d) integration of all the components

Alone, I could prototype this in about 6 years (it is that easy), so a
group of people could probably get one into pre-production testing in 12
months, and into production, 6 months after that.

The question is, would it sell. Would you buy one? Is it complete,

I would buy into this idea..particularly if the various components could be
modular and individually selected. All of what you say is perfectly
available now. In my situation, with severe space, weight, and maintenance
issues an integrated, modular system would be excellent.

I would buy a canopy that included your
items 1, 3, 5, 6, 8 but the other items either
I don't need or use, or they would seem to
make the unit too bulky to be self-contained
(e.g., the food storage items). I *really* like
the idea of the heater built into the canopy.

BTW I do have heavily planted tanks but don't
use CO2 injection and it seems to work just fine.

Perhaps manufacturers will offer a line of
canopies from basic (my needs) to complex.

Sounds good but there is one thing that I would add. This summer, as
some of you might remember, I came home from my holiday to face fish
soup in my Community Tank. Most of my fish had died due to toxic water
when the Fluval 304 failed to work (could have been for up to 2 weeks).
Unfortunately, noone had noticed :-(

Now, what I would like, and am researching implementing when I get the
new tank, is a warning system that would send a text message to my
mobile once certain thresholds are exceeded or drop too low. This would
give so many of us peace of mind....and most certainly would have saved
the lives of my fish while I was on holiday. I need to see what type of
monitoring stuff is out there right now as to how much development work
would need to be done - but I'm pretty sure it is possible to do. This
could look at water flow, mechanical workings of the pump, temperature
control, lighting levels and hopefully some essential diagnostic water
tests. Not only could it warn when things are becoming critical it could
also give trend information - say for example if temperatures fluctuate
greatly over a given time scale, or if the heat distribution is not
even.....all sorts of possibilites - I think this is going to be a fun
project :-)

Lighting alone is pretty expensive. Sounds like it would be very expensive
to make a hood with all these features. I could easily see it costing way
more than the tank it would go on. I know I am always looking for a deal, I
doubt I would buy something that was more expensive than the alternatives.
If you're aiming for the high end crowd, perhaps they use canister filters
etc that generally go below the tank. There appears to be a lot of
complicated stuff on your list, you would need a lot of customer support
that your competitors might not.

I would guess you'd make it for larger aquariums, my guess is the larger you
go the more non uniform the sizes of the aquariums will be. Odd sizes, bow
front, hexagon? I know the gap on the aquaclear 70 filter I bought was too
small to fit over the rim on my 75 gallon aquarium. Will aquarium dimensions
be consistent enough for you to market something that works well enough with
everything to mass produce. There's probably about 20 different sizes of
aquariums at petsmart and most of them have a specific canopy. My guess is
you'd have to sell it as a combo with specific aquariums, or get stores to
do so.

It seems you have two items devoted to food storage and automated feeding. I
would guess most aquarium owners would enjoy feeding the fish themselves.
And have the fish get excited when they come up to the tank. I would also
rather leave my food in the container it came in anyway. Though I suppose I
do not buy food in bulk.

What are the reasons heaters and filters are not integrated today? It seems
like a good idea, do heater elements burn out much more quickly than the
lifespan of your typical filter. Why not make a hob filter with space for a
heater component if that's the obstacle.

I didn't see an air pump on your list.

I think the temperature stuff would be no problem - electronic controls
are already available specifically for fish tanks and I would think one
of them will plug into your computer for the text messaging part of
things. I'm sure there's also non-fish-specific equipment that will do
this.

I've seen electronic pH meters as well.

For lighting, I'd bet there's something, but the easiest would be to
have something which senses a loss of power.... But then, how's it
gonna send you a message with no power? Perhaps program the UPS
software on your computer to send the text message when the UPS kicks
in (and again when it starts up again) - then you'd know your house
lost power. (This would require an "always on" internet connection -
make sure you've got good firewalls and anti-virus software in place.)

Don't look for stuff made for aquariums - it's not all gonna exist -
it's too expensive - look for stuff made for labs, plants and similar
industrial application - then pretty much everything will exist (for a
price). If you have specific questions, I'd be willing to run a few
past our metrology department (I work in a non-clinical testing lab -
in IT).

IMO, knowing if the power goes out, having redundant filters and
redundant heating would take care of the biggest concerns.

Well, some of it, like the changing lighting, sounds nice, but the
whole
thing reminds me of computerizing a model railroad - takes all the fun
out
of operating it :-).

That's very true. So automate the bad and keep the good, but that
balance differs by everyone's definition of good or bad. I'm perfectly
happy to never clean filters or do the daily feeding, as long as I get to
give the frozen food treats. Gravel vacuuming holds no interest, but I
don't mind cleaning a bit of algae and pruning live plants.

And with the number of heaters I've had die on me, I'd be really leery
of
building one into the canopy unless it was easily replaceable. In
fact,
that would apply to most of the components you've imagineered.

I'm also a big fan of redundancy and the use of commonly available
components. I imagine someone could make a fortune selling proprietary
heaters to fit this canopy, but a proper design would be to have 2
cavities where standard submersible heaters were installed. A small LED
indicator on the canopy could be optionally used to indicate operation (I
like very visual indicators), and the heater's current usage (amperage)
could be monitored (through the GFI circuit) so a no-current condition
(heater failure) could be flagged to the user.

Understood. It would be a bit of a paradyne shift. There is some
consumer demand to integrate terrestrial and aquatic flora & fauna, in
the push for more realistic slices of nature in our livingroom. Along
these lines, very tall sheets of glass could be used, such that a 48"
tall aquarium would only be filled halfway with water, leaving the upper
24" for small shelves (rock appearance) for bog plants, water elements
(small water fall), flowering aquatic plants (some need a lot of
headspace above the water), and terrestrial critters (some insects,
amphibians, reptiles etc as space allowed).

If this sounds attractive, there are many drawbacks i) the glass
thickness cannot be reduced for the upper portion (manufacturing
constraint) making a very heavy and expensive structure, ii) maintenance
access is horrific (our reach is only about 24" to reach the bottom of
the tank), and the upper terrestrial portion of the tank would tend to
have condensation negatively affecting our view.

The work around is a bit of a hybrid on the idea, by integrating some of
the nicer aspects into a canopy. This allows less expensive materials
for the terrestrial portion, better access (canopy sections open to more
easily reach the bottom of the tank) and the use of plastics which would
promote less condensation obscuring our vision.

The canopy becomes another biotope, and hides all the mechanics to
support both terrestrial and aquatic biotopes. It's just food for
thought ). Thanks for the feedback.
