Hello everyone would like to introduce myself! I've got the bug after months of research I've decided to jump in on a tank of my own. I have a 36 gallon bow front tank. I bought it used with a marineland 375gph filter, and a titanium heater(not sure the brand) It came with a lid that has a simple LED light built in. I plan on starting with Fish and moving into Coral later on down the road. I'm about 3 days into starting the cycle. I was wondering if anyone could help guide me on what is the first things I should buy before buying fish when that time comes? Do I need a WaveMaker in the beginning or a oxygen pump of some sort? My filter moves water pretty well. I removed the 2 bio wheel filters from the Mairneland filter as people say they turn into "nitrite factories" but I'm still using the Carbon filters. I just want to make sure I have everything I need as we all know it gets costly very quick! I don't want to rush anything and plan on getting fish without the proper equipment. Thanks in advance for any advice I'm just trying to be a sponge and soak up all the knowledge I can!
