I am in the process of converting my 30g nano reef tank into my sump refugium for my new 55g reef tank, I have done DIY skimmers and moonlights but this seems slightly more complicated. I love learning and want to do this myself instead of purchasing a sump, love to get my hand dirty! I am just unsure what is needed and what the best build is for my tank? Any and all help would be greatly appreciated and if I need to put in more info please let me know. Thanks
