While everyone has been having fun at Tonmo II, I was hand sawing wood in my bathroom building my new tank! It is a new 150 setup to hopefully house Sepia Officinalis. I didn't realize it was going to be such an undertaking and even though Ive done most DIY, Ive spent a good amount of money so far. I live in a loft with no garage and a concern for making too much noise, so much of the wood I had to hand cut. I'm going to start looking like a fiddler crab soon with the amount of exercise my right arm is getting. Here are the basics to the tank: -150 gallon display glass tank (Drilled the back bottom two corners to create two 1 inch overflows) I didn't drill the bottom for it was tempered glass. -AquaEuro Recirculating 265 skimmer (Plumbed external from sump for less heat) -30 Gallon sump with DIY trickle wet dry containing 1 cubic foot of biobale and a small refugium. -PanWorld 50PX-X (Externally plumbed With a fan modification dropping the tank temp 2 degrees) -Wavy Sea wave maker -Icecap Vortec pump for circulation and less heat. (I know expensive..Very nice flow, circulates water ALL over the tank without too strong a force or suction. Im incredibly impressed with it) -Dual 250 Watt MH and 4 36" T5 39 watt for lighting. (MH will only be on for a couple hours a day) -Custom made Stand and Hood I still have a lot of work to do, but thought Id share my project. Here are some pictures- Current State of the tank With an almost finished hood. (The Rock work is temporary for I'm waiting for some agrocrete shelf rocks i made to kure. All the rocks in the tank will be placed on top of the shelf rocks which will be 6-8 inches off the sand allowing for a lot of surface area for the cuttles to bury and play) Sump and Skimmer Return pump with Fan mod (Looks pretty Star Trekky) Inside the hood (Still need to add T5s) I was attempting to design the tank to have the lowest temperature possible. It seemed to be a good design for water temperature is usually 2-4 degrees above ambient. Sitting at 77-79. With a fan for evaporation, I was able to get it to low 70s upper 60s. Mostly, I wanted to post this to document and share my new source of joy and frustration, but if you have any questions or comments, they are greatly welcomed. I have a million pics from the process of my tank build also, so If you want to see something in detail, just ask!
