I am getting ready to start my first cichlid tank(46gallons). I am wondering what type of substrate to use? I was thinking sand because it is the most natural and it looks good, but I heard it is very hard to clean. What are your thoughts on which substrate to use and if you could also include what brand and specifics of the substrate that would be great. I don't want anything that takes a lot of work to clean. My last question is: how hard is it to really clean aquarium sand because I have heard it takes time and practice. Thanks
