(discussion based on this poll on water changes...

I was most amazed at cracker's w/c's, being 30% every 6 weeks. Less than I thought and still a fantastic tank.

Another question about water changes: if you were to store a large quantity of water for several changes over several weeks (in my case, 1,000 litres for 10 x 10% weekly water changes) do you think it would be more beneficial to leave it "dead" or place a powerhead in there for continuous aeration and change it "live"? Would one method be better than the other? does it really matter?

I do the same thing Chim, Just leave it dead in a dark environment until you need it. (Ive had mine sitting for up to 3 months. No probs.

maybe that's the key :wink:

I run mine through an activated carbon filter before it hits the tank though.

you mean have all of it pass through a carbon filter before it hits the tank or have it under constant carbon filtration for those 3 months?

at what lph? would that be enough contact time? better than nothing i suppose. as i mentioned above, to do smaller but more regular water changes, i put a 1,000 litre container under my house (had to hack into the wall to get it in there and make a quick retainer wall for it :D ) for water changes. i gotta raise it up though as the tap at the bottom is lower than the sump at the moment.

does anyone know what type and where to get a fitting for the bottom tap on the 1,000 litre containers? ie these ones:

i see one dude has a fitting to attach a garden hose to it but it's $40 :-? must be cheaper fittings than that. i still have to get a ball valve in the sump room to ultimately control water to the sump when doing changes.
