Hey everyone. Just want to say thanks in advance, as a newbie I have had so many questions and everyone here has been so helpful and I'm very appreciative!
So, on Monday I will finally have my heater arrive. My question is, when doing 50% water changes, whats the best way to introduce the new clean water since the room temp is going to be a lot cooler than the heated water in the tank?
Do I slowly introduce the new water (if so, how long do I let it sit in before I add more?) Or do you just do the good old finger test and try to make the new water similar in temp to the water already in the tank?
