there are 2 schools of thought on that.
I leave mine 'down', and set it up with water from my tank as necessary.....
some leave one running all the time, but I already spend enough on my tanks![]()
My wife says she does in the morning, but I dont see anything. So they must be there. I am going to wait, because as many different stories I get for every question, the one thing I keep hearing is patients, When I eventually do a Qt tank do I start that now and always leave it set up, or do you set it up and maintain it before you purchase new fish?
I keep it running all the time, but if I'm planning on bringing something new in, I'll do a good sized water change on my main system and use the old water to do about a %75 water change on the QT system. This way the QT stays somewhat biologically active, but it also gets all it's parameters corrected right before the new addition.
