Hello, I'm new here and new to saltwater. I've thought about saltwater off and on for a very long time and I've decided to take the plunge. I'm looking into learning all I can with the ultimate goal being a reef tank and a mantis shrimp tank. No doubt I'll want to make more as I go, but I'm here to read and listen to learn all I can to purchase and set up an appropriate tank for a peacock mantis. Currently trying to decide on an AIO vs jumping into the deep end and making my own acrylic with a sump. I'm thinking 36x18x16 if I make my own. I want maximum floor space for growing a peacock, a forever tank so to speak. If I decide AIO I'm thinking a 30 gallon minimum, most likely a 40 gallon. So let's hear it, as I Google and YouTube all the things I want to hear your tips and advice. Good brands for tanks, filtration, pumps, chemicals, substrate, heaters, thermometers, test kits for water parameters all of it. I'm here to learn!
