I am wondering if someone can answer a couple questions before I put fish into my tank (hopefully this weekend). My water parameters seem to be testing out okay but I am going to have the guy at my local fish store test it and give me the numbers (he will do it for free) so that I have a second opinion before putting any fish in there. I did not have a powerhead in my aquarium for my cycling process and hopefully that does not mess things up. I have them in there now (as of the last couple days) but have no idea how to tell where to place them so for now they are just creating some flow. This brings up two questions for me.
First, should the powerheads have been in there during the cycling process and if so what adverse effects could that have caused to not have them in there?
Second, how do I figure out the best placement of my powerheads?
Thank you for any help you can give me.
