Hi Everyone ;-)
Well the "Fan is spreading the crises everywhere" so as far as I'm concerned I'm preparing a new system of 100g (350~380 litres) which receives direct natural sun light early in the morning (when there's no clouds and/or rain) during some one and half to two hours every day, perhaps reduced to one hour in winter (we shall see). If needed I can have it receiving 4 hours or more, but so far this is part of the plan. In addition to that I'm about to order this
solar pump for my KOI carp pond for try-out, already having in mind this
heavy duty solar pump from SHURflo to replace the conventional Eheim pumps that I use in the marine systems. Well this off course leaves behind so far the skimmers, heater and the lighting system of both tanks for the most part in one of them and so far completely in the other, but a window can be opened and then sun light will lit it as well. Any way I go step by step to make sure the thing works, and if not, then I'm able to perform the necessary adjustments, on a money wise/cautious application. With this I plan to reduce energy costs, provide the corals and fish some natural source of light and progressively change for
alternative renewable energy sources where possible to
apply. It'ill take time and things are not becoming easy economically and environmentally speaking, but will find a way, I try to think a bit like
Asterix and Obelix the
famous Gauls do

The worst thing that can happen to us, is the
sky falling on our heads, but since today it is not the eve of that day, will be all right

...I hope...off course the
world changes and it hasn't been always as we know it, and there was a time, four times to be more exact, that coral skeletons changed from aragonitic to calcitic and back again in relation to high or low CO2 levels in the atmosphere, as so well Ronald Shimek explained us here in Portugal recently in his presentation of The Rise and Fall of Coral Reefs, which I hope to bring here to Manhattan Reefs (I have it in my computer, 41.5 MB file, but must have permission form the author Ron Shimek to divulge it here).
