Ok so this is my first sw tank the names Danny. I'm going to pick up a Hagen 130 show tank in the next couple of days and a Fluval 205 swell as the 405 I'm hearing do not use the 205 due to no air pressure so I'm selling that at a discount to a buddy my main question is after I have bought my second 405 what would you recommend I buy. Not to sure about anything yet if anyone could point me in the direction of what I may need to get to house a reef and fish safely and friendly no aggressors keep in mind it's 130 gallons for this newbie I have tons more questions but this will do for now
