I planned on getting an Oscar for my new 55-gallon tank. I put 50 lbs of rinsed pool filter sand in there and minimal decorations, a few rocks I tested with vinegar. I have the heater on 80 and the double bio filter running with old filter pads in it. I also have a few socks at the bottom stuffed with mature gravel from another of my tanks. I have yet to add any ammonia (not even sure how much to add yet), but I have two questions. One is, am I doing anything wrong with the above?...the other question is it a good idea to put my single male betta I have in there for the cycling?...I also have a 7-inch pleco I want to eventually add to the baby Oscar when I eventually get him (I'm aware that some people add plecos and some do not). Would it be okay to put that pleco in there now or a bad idea? What are some other things I can do to help speed the process? (in the vein of the gravel-filled socks, etc.) Thank you everyone for your feedback!
