Hi, couple of questions - just starting a 125 litre tank, can I wash some sand substrate and leave it in the tank (without water) for a while say 2 weeks without there being any problems (tank is under stairs, and is shady, temp is about 25) ?Also building on from that, could I setup the tank fully (adding live plants) turn on the filter and heater and get the cycle going, but after about 1 week turn off electric (going away for 4 days) and resume cycle when back. Would tank be okay to continue without any probs?

The sand can be left in the tank without water with no problem. It'll be just the same when you do add water.
Why not just let the filter run while you are away? Once there are fish in the tank you'll need to leave the filter running then so just leave it running now.
