Below are some quotes from the TFH book "Light in the aquarium" by
Rolf Keubler (first edition 1968 with 1973 copyright for English
translation) regarding aquaria stocked with fish and plants. Some of
the things Keubler's written may have merit, and I'll continue to
slack off on maintenance for now. Comments?
d.
" The more favourable the biological "harmony" between water and plant
(the balanced aquarium), the more beneficial is the effect of good
lighting on the aquarium!".
"Some time ago one often spoke of the 'balanced aquarium', meaning
that the biological influences, e.g. bacterial activity... become
adapted to another and counterbalance each other."
"Someone who, for instance, with a powerful pump runs all the water of
the aquarium through a filter 10 to 20 times a day, certainly manages
to bring the water to an artificial nominal value." Comment, my main
aquarium has 2 big canister filters that probably recirculate the
water 4-5 times per HOUR!
"An example of this: two different tanks... after a year filtration
switched off... merely weak aeration via airstones, and also a partial
water change with humus extract every three monts... surprise
occurred: the water had acquired an extraordinary clearness... a year
after fitration ceased the (plants) more and more suffocated by the
excessive growths of green and blue-green algae...".
"... biological change of the aquarium water, unless constantly
encouraged artificially, only comes about very slowly... "
"...filtration must have only a weak effect in order to fulfill its
function".
Slack on, my friend. Whatever old tanks your syndrome.

If/when I have the time, I'd like to put together a self-maintaining
system (where the only artificial inputs are light, heat and water
circulation). Sailfin mollies might be a good candidate, being algae
eating, protein skimming omnivores, if only they wouldn't breed
themselves past the system's capability so quickly. That way I'd only
need perhaps 3:1 ratio (75g of plant/invertebrate culture).
Alternately, a small carnivore, but a much higher ratio of culture
would be needed (more animal like worms, shrimps etc and more plant to
filter the extra waste). Perhaps some Paradisefish in conditions
where their fry would not do well.
In any case, ymmv with old water/slack maintenance, depending on your
setup. I've seen tanks which were taken out of service (no
electricity, a few fish) and if they received sunlight and the bio-
load non-critically stabilized to a low point, the tank looked
pristine.

Tanks for the advice NM and MG. I'll watch for that old syndrome, but
as long as the pH is neutral or above it may not apply, eh?
My aquariums are heavily planted, even the little snail aquarium.
They've now all gone a month before maintenance, and the snails seem
no more smelly than usual.
Since rediscovering T. Barr's methods a year ago, I've been doing big,
fairly frequent water changes. Hopefully the slacker approach will
work too. Can you imagine 6 weeks, 8 weeks between major
maintenance??? That will leave time for gardening, barbeques, biking
and walking around town, camping trips... all the good things of an
Ontario summer :o) .

My karma ran over my dogma. And no, I'm not going to explain that one.

Maybe summer somewhere - we're still firing up the wood cookstove in the
morning.

Denizen, water changes are doctrine, even mantra for new hobbyists.
Here; knowledge teaches why, experience teaches why not, practice
teaches how much and wisdom tells us how far ;~)

My main aquarium is a heavily-planted, moderately-stocked 90gal. So
far the only drawback to letting it go a month is, that the floating
plants became thick and now my platy population is starting to
burgeon.
I'm undecided on maintenance routine for my smaller aquaria this
summer. Have let them go a month this time, but may step up
maintenance if they seem to go down hill.
d.
Experienced hobbyists can often see some sign with some of their tanks
(not all), but new hobbyists don't really have a chance of seeing
anything before it's too late (OTS, diseases, mutations, deaths, crazy
algae etc). Sometimes I like pushing the envelope and looking for
signs. Other times, I just drag the water-change pail out like
clockwork ;~)

This brings up a subject for another possible "how come?" thread. How
come there seem to be few newbies posting to TFA? New posters to the
group turn out to have kept fish for years, and/ or they work in an
aquarium store!
Are newbies' needs being met by web sites instead of discussion
groups? Is TFA not well advertised? I think it is, at least Google
finds it readily? Is TFA's natural domain the experienced fish keeper?
Possibly true - newbie problems are predictable and perhaps boring
because we all experienced them ourselves long ago...
Perhaps managers need a designated newbie-welcomer each week? A
simplified Krib? Or perhaps TFA isn't really for newbies...

Not here at southern hemisphere. ;) But even though is not that hot now
(it's a rather rainy autumn this year), today's temperature (27ºC / 80 F)
can look like summer to most of you.
About water changes: in the past, when I had FBF on my tanks, I used
to do only major maintenance on them on a period of aprox. 8 weeks.
After I learnt with my personal disasters, I changed filtration and now
I do water changes almost weekly, about 20% of tank's volume.

Back to the original topic - beginners. TFA members have been terrific at
giving tons of support and advice to beginners, advice that is customized to
the individual's equipment, budget, and expectations. Quick responses to
questions can take a beginner from a monstrous mess of a first tank to a
healthy and ever improving experience in a rapid exchange of messages - all
in a day's work. I don't see this level of interaction on other forums. I've
tested a few with questions of my own, and have waited days for a response,
and some have received no response at all. That doesn't happen on TFA.
My first forum was back in the days before the web and AOL. There was
Compuserve and there was Delphi. On my forum, we had a standing offer that
we would award $100 to any lurker that revealed themselves. Naturally, as
soon as a lurker stepped up for the prize, they had blown their lurker
status and disqualified themselves. You'd be surprised how many lurkers came
out of the closet, and became active participants in our ongoing silliness.

I think maybe TFA is mostly catching people who have been on basic
fish discussion groups in the past, like usenet and compuserve. That
means it would tend to attract people with more experience. I suspect
the newbies are going to the big phpBB style forums.

We try to our best to welcome all the new folks. Apologies to anyone

Yes, you're probably right - TFA attracts people with at least some
aquarium experience, people who're becoming serious aquarium
hobbyists. Therefore the technical nature of some of our discussions
is ok, and if a mom or dad who's aquired their first family aquarium
writes with a question, it'll be answered as simply and appropriately
as possible.
