I have 2 freshwater tanks already set up. A 37gal community tank and a 45gal cicklid tank. I will be making a 20gal long for my baby axies and I will be doind a water change soon. I was wondering ifI could just pull some water out of either or both of these tanks, check the water parameters, and if theyre alright, I wont have to cycle the tank? Correct me if Im wrong, but both of these tanks have been cycled and have been up and running for almost 2 years for the cichlid and about 6 years for the community. Correct me if Im wrong and thanks in advance. If I cant do this, could I fill the 20gal long tank up and swish around the filter pad from one of my established tanks to get some bacteria going and start its won cycle? I would love to just do a water change and already have a cycled tank, though. So this would be amazing. Thanks again.
