Here are some shots of my new cuttle rearing system. Mike (Coral Reefer) and David (lattehiatus) were instrumental in helping me get this together. I hope to start by ordering some cuttlefish eggs and live mysids after Thanksgiving. I am sure it will take a few trys to get this right, but I am excited about the journey. The Main Tank 125G custom acrylic built by ZeroEdge in Chicago. The lights are DIY LEDs. I still need to aquascape the rock. Plumping The drain is a BeanAnimal(ish) design: one full siphon, one open channel, and one emergency siphon. In a true bean animal the open channel should be able to go full siphon, but in my setup, this tube goes from 1" to 1.5" so I can Tee in the gravity overflows from the support tanks. If this goes siphon, it causes some water to push up out of the silencers in the support overflows. Everything drains out through the wall to the closet behind. You can also see the DIY LED power controller. Yes, I need to hope I don't spring a leak. This is the "ultra-flex" PVC from MarineDepot, although 1/2 of it is not what I ordered, so it is really a combination of regular spa-flex and ultra-flex. The gate value is for the full siphon. The trick to running the full siphons such a long distance is that the tubes must run continually go down. If they don't, they have trouble starting. The open channel and the return are the ones in the back going up and then down. In my setup the open channel won't go full siphon. The emergency drain will and it will make a lot of noise so I know the main siphon is clogged. The Sump 36"x16"x18". This needs some wire management . I will wait until it is all dialed in before making it more permanent: ATB 804v2 cone skimmer NextReef SRM biopellet reactor (far left in blue) BRS dual reactor for GAC and GFO Refugium w/Chaeto and Home Depot LED Two returns, one for the main 125DT and one for the two 20G and 29G tanks. ATO: line from 6-stage RO/DI unit, float switch that activates a solenoid, and a manual float switch that the RO/DI line runs through in case the float switch fails BRS 2-part Dosing Pumps (not shown and not yet installed - currently dosing manually since load is small) The Support Tanks The Blue are plumbed into the main filtration system for the 125G and the pink ones are standalone with a heater and a sponge filter.
