Since my main tank is no where close to a sink, I have to do the bucket system.
Before I start my water change, I have to get the new water ready
~I have to match the temperature and treat it.
unplug the filter and heater.
drain the water to half way.
~once a month or two, I siphon out the waste build on on the substrate
pump the new water into the tank slowly
plug in the filter and heat
sit back and enjoy the tank
ALWAYS make sure the temperature of the water is within a reasonable range
Water your garden/lawn with the old tank water
