I'm relatively new to being serious about the hobby of fishkeeping. I searched this forum, and the wise God google with only some topics brushing on my question. So I turn to you glorious gurus!
My question is, when I am doing 20-30% water changes in my 20 gallon H tank, with a PH of around 6.8, should I aerate the water while it sits before I add it to my tank?
I saw a lot of information for aeration regarding salt water, but not about freshwater. I currently have a heavily planted tank with no CO2 yet (I'm still waiting on my diffuser to arrive). I read that too much movement of the water may "push" the CO2 out of the water. But when I do a water change, I immediately fill the bucket, treat it with prime and then let it sit for about 3 days (right now as the tank is still relatively new) before I do my next water change.
I have a small heater that I put in the bucket to keep the water around the same temperature as my tank, but it has no movement while it sits. I do cover the bucket (with my "dirty water bucket") because any open water source in my house is free game for drinking water and pet hair.
There are currently 5 harlequin rasboras and a snail in the tank. Eventually it will house 5 panda cories, my betta, 10 rasboras a mystery snail or two and a small colony of shrimp.
So moving forward with the maturing of the tank, should I begin aerating the water change water? Or is what I'm doing ok to let it sit covered, treated with prime and a small heater.
