At present I am considering doing away with all my tanks. This is
because I will be moving house for a short spell, and then moving again
(hopefully) into a newly-built house, considerably smaller than the
rambling farmhouse I have now. The new house probably will not be
connected to the grid and will have a generator to supplement a
photovoltaic array that will slowly increase as I get together the clams
to build it up.
This presents something of a challenge. Does anyone on the list have
experience in running a 12-volt system? Of particlular interest would be
information dealing with low temp. plants (for instance, it is said that
some echinodorus species require near freezing temperatures in their
cycle), or a way to heat a smallish (140 litre) tank without draining
the house batteries. It occurs to me that an automatic water changer
could possibly be used in conjuction with a small solar collector in a
closed loop driven by a small solar pump; what is defeating me at the
moment is a means to regulate the temp. of the tank i.e., if the tank
suddenly recieved a dose of water at 65 deg C the plants would probably
Does anyone have any ideas? The thought of having to do away with the
tanks is pretty depressing, especially as they have become pretty sexy
with all the help and ideas I've picked up from this list.
On the bright side, the property I'm looking at has a half million litre
dam on it. What a pond!
This is a pretty off-topic subject so perhaps responses should be sent
to my e.mail address.
Cheers, Chris Holloway.
Ps. If there's anyone on the list who lives close to Canberra Aust and
would be interested in some cheap second-hand systems drop me a line.
