Hi there I'm starting a 40g reef tank. The tank itself is a 40g breeder (36x18x16). I have a 150 watt t5 HO light system. I am planning on keeping both corals and livestock. I plan on using fiji live rock.
This is my second system I am creating. My old one is 125 gallons and has been established for 8 years now. I have since moved from home and am currently attending university and have limited space which is why I am making a 40g tank.
That being said, it has been a while since I have started a tank and I have some questions.
Filtration is something I am debating about at the moment. My 125g uses a wet/dry system (I have done some browsing on this forum and have come to the conclusion that wet/dry systems are a taboo topic. I now understand why this is). The filtration system I am looking at for this system is a combination of a sump and refugium. So a 3 chamber sump system, 1st chamber for inlet and skimmer (maybe heater as well), 2nd chamber refugium, 3rd chamber return. Only problem with this system for me is finding a place that sells one I like. Would it be cheaper or easier for me to make one myself or have someone make it for me?
Something else that I'm not too sure on is sand. I have been told many different things by many different people about what sand to use. Live sand, argonite sand, crushed corals. Whats the difference and benefits of each?
My last question is, would an open-top be ok, or would I have to get a top?
Thanks for taking the time to read, and I appreciate any feedback.
