Hello everyone my name is Trey and I'd like to thank everyone already for all the help while a stalked the forum before joining! I'm a soon to be new reefer from Dallas, Tx. I'm currently in the process of planning my purchases…from tank to pumps, lighting, and etc. I’m currently, focused on a lot of the Red Sea equipment. I’m thinking about the Red Sea 170 but I can’t decide yet between the AIO system or the reefer system with sump. My only worry with them is the use of the metric system for plumbing. Hopefully, that won’t be too much of an issue?! Thank you so much in advance!
