adding a fuge
Adding a refugium is a great alternative to downsizing.I put a 30g long under my 55 with a few baffles siliconed in , used an old aquaclear 300 HOB with a skimmer tube and bulkhead drilled into the bottom for the intake,and put an aquaclear4000 powerhead with a ball valve for the return.Easy cheap and looks good.The added h2o volume really helped with the water quality.Alsothe addition of more LR and another DSB combined with the look and benifits of macro algae make it a way more fun and enjoyable way to keep yourself busy along with enhancing the quality of life in the main tank.My kids really enjoy looking at all the life in the fuge.I added some polifera,razor and chaeto to it and my pod population exploded.There is tons of other life in there that was in the sand that never had the chance to populate in the 55.Micro stars,feather dusters,even sponges will start poping up everwhere.I even put a mantis shrimp in my intake side,he loves it!!Hope you give it a try!!!
