[APD] Re: What is "low tech" by todays standards?
I think low-tech really referred to systems without artificial CO2
augmentation. If you use a natural soil, such as you might find in the
garden, and the lighting levels are not excessively bright, you can get very
good growth without CO2 injection, simply availing of the CO2 generated by
the decomposition of the soil. I would greatly recommend peat in this regard
because of its superior stability and low nutrient levels.
The classic definition of a "low-tech" tank from the mid 90's seemed to be a
tank that (1) did not use supplemental CO2, (2) did not use substrate
heating coils, and (3) in some cases used minimal supplemental nutrients.
Substrate was often mentioned too, but I always read "low-tech" to usually
mean minimal technical gizmos like the heating cables and CO2 (especially if
used with a controller).
I think now a low-tech tank is a tank without a CO2 *controller*, but
probably still with CO2. Substrate heating coils seem to have fallen out of
favor in recent years judging by the lack of posts regarding them on this
list. Lately substrate discussions often seem to be along the lines of "how
does substrate [x] compare to Flourite?", which implies that many think
Flourite to be the ultimate planted tank substrate for most applications. I
see a lot more talk about what used to be "advanced" light technologies too,
with PCFs seeming to be the standard now even for low-cost DIY setups where
everyone used to use T8 fixtures.
A higher percentage of people today seem to have what would have been
considered "high-tech" tanks some years back. I think what we're seeing is
just a natural evolution of the hobby as aquarists discover devices and
methodologies that work and those that don't, with those that don't or that
have a poor price/benefit ratio falling out of favor. Recent list years seem
to indicate more emphasis on nutrient balance than on tech gizmos, but some
of the earlier tech gizmos seem to now be more of a must-have item than
before (notably some kind of pressurized CO2 system). A "low-tech" tank
today would probably have been a mid-level tank of years past, with a
"high-tech" tank today adding a CO2 controller, maybe some fancy lights
(MH?), and possibly even substrate heating cables.
