Everything sounds good! Its ok if the solution touches the net pot a little. I usually make it to where the waterline is just below the pot and the surface bubbles touch it. When she starts to drink alot this will help with how much you have to add to the res. 65f is a good number to shoot for but I dont think you will be able to achieve it without some sort of cooling. Right at 75f is when things start to go bad. Good luck my friend and may the bud gods be in your favor
