So some of you were following my 45 gallon Coldwater build. Well I jumped of the deep end and traded my carpet anemone tank for a marineland lobster tank. I know I have the 4x4 build going also but I have a plan and so far I am out 40 bucks so I can do foam rocks. Here is the set-up, it is a 110 gallon display up top with a 30 gallon sump below. That's were the chiller "wire" runs in loops. It has a fiberglass grate covering this part and is slotted to allow for reverse flow so keep the bed free of detritus. It has a reserve area between it and the floor of the tank. I was think bio-ball in this area. I was going to put in pourous rocks but weight is a factor due to the flimsy fiberglass. For filtration it has two airlines that run up two tubes that lead to a media basket and out flows the water. Don't worry I will post pics tomorrow evening to show what I am saying. It also has a drain but I'm not sure where that's coming from. Or where it was leading to. Also the the tubes to the media basketconfuse me. I may just run power heads on the tubes. And have them spray water into the media basket and call it good. Rather than have an airpump do it. I filled it tonight to do a leak test and test the chiller. My living room is 78 right now and my tank ks sitting at I have it cranked down and it is at 41.1 after plunging my arm in the frigid water to mix up the cold water. Yep that's 140 gallons dropping 37 degrees below air temp. And with the double paned gas injected glass panels there is zero sweating oops quick update I just hit 40f lol.
